Sustaxyl 350 is an oil based injectable testosterone blend that is containing 4 different testosterone esters that includes: testosterone isocaproate (84 mg), testosterone propionate (42 mg), testosterone decanoate (140 mg) as well as testosterone phenylpropionate (84 mg). This product might be better known by its other more famous trade name – Sustanon and there’s no difference between the 2 products.

With this being said, Sustaxyl is made to offer a fast but in the same time an extended release of testosterone, usually, this is requiring injections once only every 3 to 4 weeks in the clinical settings. It is considered that this is a great improvement from the standard testosterone esters such as enanthate or cypionate that is providing only a shorter duration of activity after is administered.

Since Sustaxyl 350 is made all out of testosterone, it is obvious that exactly as with all other testosterone products, Sustaxyl is also very strong anabolic compound with some pronounced androgenic activity. For all these reasons, Sustaxyl is most commonly being used in bulking cycles as is providing exceptional gains in the strength and in gaining muscle mass.

By purchasing this product from Kalpa Pharmaceuticals, you are expected to get 350 mg/ ml of Testosterone mix (Testosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate, Testosterone Decanoate) U.S.P. (10 x 1 ml amp) with an active life up to 3 weeks but detection time can be more than 3 months. This is one very famous steroid that is widely used by bodybuilders.

Below you are going to find some important questions such as: What is Sustanon (Sustaxyl)? How To Take Sustanon (Sustaxyl)? and Where to Buy Sustanon (Sustaxyl)?

Estrogenic Side Effects of Sustaxyl 350 (Sustanon)

As everyone know (or should know before using such products), testosterone is readily aromatized in the body to estradiol (estrogen). The aromatase (estrogen synthetase) enzyme is being responsible for this metabolism of the testosterone. This means that by using testosterone you are most likely going to have elevated estrogen levels. But, high estrogen levels for a man can offer side effects and it is widely known that many steroid users are often fighting with the high estrogen levels and their side effects which are including: body fat gain, increased water retention (which can lead to high blood pressure) and gynecomastia.

But remember that testosterone is only considered a moderately estrogenic steroid if comparing to all other steroids available. Usually, an anti estrogen like for example clomiphene citrate or tamoxifen citrate may be required in order to prevent the estrogenic side effects. There are the least sensitive people who may not require anything at all, but it greatly depends on the sensitivity and on the dosage used.

Most men would find that an anti estrogen should be enough to fight off their estrogen related side effects however others might need an alternative medication, the use of an aromatase inhibitor like for example Arimidex (anastrozole) which is a product that is much more efficiently controlling the estrogen levels by completely preventing its synthesis. Even though this product is much stronger in dealing with estrogen related side effects, it is not for everyone as aromatase inhibitors can be pretty much expensive by comparing them to anti estrogens and plus to that, they may also have some negative effects on blood lipids either.

Remember that the estrogen related side effects would occur mostly depending on the dose that you administer. It is obvious that with higher doses (higher compared to the normal therapeutic doses) of Sustaxyl (or Sustanon) 350 is more likely going to require the combined use of an anti estrogen or aromatase inhibitor as the higher the dose gets, the higher the chances of getting side effects would be. Due to the fact that water retention as well as loss of muscle definition are common side effects with the higher doses of testosterone, this drug is most commonly considered to be a bad choice for dieting or during the cutting phases of training as people tend to lose the water retention and keep muscle definition during this period.

But this product, on the other hand, is extremely helpful for bulking phases, especially since it has a moderate estrogenicity which can help, compared to other steroids that do not have it and that’s because the added water retention is going to help and support the muscle size and raw strength and it is also going to support the growing of a stronger anabolic environment.

Androgenic Side Effects of Sustaxyl 350 (Sustanon)

Testosterone is the primary male androgen which is responsible for maintaining secondary male sexual characteristics. The elevated levels of testosterone are more likely end up in androgenic side effects where usually they are including: acne, oily skin as well as body and/ or facial hair growth. in addition to that, those men that are predisposed (genetically) for hair loss (androgenic alopecia) they also may notice accelerated male pattern balding either. This may not be an issue for those who are not predisposed to this side effect, but this can be a real concern for those who are predisposed to it and are concerned about it.

As a recommendation here, those people who are being concerned about the hair loss they are recommended to search for nandrolone decanoate and that’s because they might find it a much better option for them since this product is a much less androgenic steroid which therefore have much less chances of offering this side effect.

In addition to that, women are warned of the potential virilizing effects of any anabolic/ androgenic steroids, but they are especially warned when considered to use a strong androgen like for example testosterone (Sustaxyl 350). Except for the fact that testosterone is a really strong androgen, Sustaxyl which carries 4 different esters of testosterone is really long lasting which is even more dangerous for a woman. Usually, the virilizing side effects include: menstrual irregularities, facial hair growth, a deepening of the voice, clitoral enlargement as well as changes in skin texture.

Usually, these side effects disappear as soon as the drug is discontinued. However, they disappear only if the drug is discontinued at the onset of the first symptom. In case the symptoms are ignored and the drug is kept on using further, there’s a chance the symptoms would become permanent.

In the androgen- responsive target tissues like for example the scalp, skin and prostate, the high relative androgenicity of testosterone is highly dependent on its reduction to dihydrotestosterone (DHT). The 5-alpha reductase enzyme is being responsible for that metabolism of testosterone. The concurrent use of a 5-alpha reductase inhibitor like for example the dutasteride or finasteride is going to interfere with the site specific potentiation of the testosterone action and this is going to be lowering the tendency of the testosterone drugs to produce the androgenic side effects.

Also, I find it pretty much important to remember here that the anabolic and androgenic effects are both being mediated via the cytosolic androgen receptor. The full separation of testosterone’s androgenic and anabolic properties is just not possible and that’s even with the total 5 alpha reductase inhibition.

Hepatotoxicity Side Effects of Sustaxyl 350 (Sustanon)

As it has been discovered, testosterone is having absolutely no hepatotoxic effects and for this reason, liver toxicity is very unlikely to happen while administering Sustaxyl 350. There’s a study out there  which has examined the potential for hepatotoxicity with high doses of testosterone by administering 400 mg of this hormone per day (which means it has been administered a total of 2,800 mg per week) to a group of male subjects.

The steroid has been given orally so in this way higher peak concentrations would be reached in hepatic tissues compared to the intramuscular injections. This hormone has been given every day for a total of 20 days and even so, it has produced barely any changes (nothing significant) to liver enzyme values including alanine – amino – transferase, bilirubin, serum albumin as well as alkaline phosphatases.

With all of this being said, even the most sensitive individuals, hepatotoxicity should not be a problem. Keep in mind that testosterone alone doesn’t give any liver toxicity, however if this product is being taken alongside a product that might stress the liver – Sustaxyl definitely won’t be helpful in such a case. Liver enzymes should be regularly checked in such a situation.

Cardiovascular Side Effects of Sustaxyl 350 (Sustanon)

The anabolic/ androgenic steroids can have some really negative effects on the serum cholesterol, some of them might have a more negative impacts others less, but in the end the result is the same – they all have negative impact on serum cholesterol.

Usually, this is including a tendency to reduce the HDL (good) cholesterol values and in the same time to increase the LDL (bad) cholesterol values, and these changes are really bad as it could change the HDL to LDL balance into a way that can greatly increase the risk of arteriosclerosis condition. If you’re thinking about using a steroid remember that the relative impact on an anabolic or androgenic steroid on the serum lipids is depending on a few different factors, some of them are: the dose you are using, the route of administration (either is oral or injectable), on the level of resistance to hepatic metabolism as well as on the type of the steroid (either is aromatizable or non aromatizable).

But in the end, if you have some cholesterol issues, it is not recommended to use any steroids at all. Keep in mind that anabolic/ androgenic steroids can also have a negative impact on the blood pressure and on the triglycerides, they may reduce endothelial relaxation, they may help with left ventricular hypertrophy and all of this can increase the risk of getting cardiovascular disease as well as myocardial infarction.

Talking about testosterone itself (Sustaxyl or better known as Sustanon) about the cardiovascular impact, it has been noticed that it tends to have a much less negative effect on cardiovascular risk factors than the synthetic steroids. it has been discovered that this is due in parts to testosterone’s openness to metabolism by the liver and this is allowing it to have less effect on the hepatic management of cholesterol. The aromatization of the testosterone to the estradiol (estrogen) is also helping here to avoid the negative effects of androgens on the serum lipids as those steroids that are non aromatizable are known to be much worse for the cholesterol than aromatizable steroids like Sustaxyl.

There’s a study which was done where 280 mg of testosterone ester (enanthate) per week has been given and it had only a slight but definitely nothing statistically significant effect on the HDL cholesterol after keeping this protocol for 12 weeks, however when it has been taken the same way but with an added aromatase inhibitor then a really strong decrease has been noticed (a decrease of 25%). Those studies that are using 300 mg of testosterone ester (enanthate) per week for a total of 20 weeks without an aromatase inhibitor has shown a decrease of only 13% in the HDL cholesterol.

Then, when the dosage has been higher – 600 mg per week, then the reduction has reached 21%. There are other steroids out there which are offering a lot much less negative effects than these. The negative impact of the aromatase inhibitors also should be taken in consideration before someone would decide to add it to the testosterone therapy. In case you already notice cholesterol issues while being on testosterone alone, it is strongly recommended to avoid adding the aromatase inhibitor to your plan.

Because of the positive effects of the estrogen on the serum lipids, tamoxifen citrate or clomiphene citrate are being much more preferred to aromatase inhibitors for those people who are being worried about the cardiovascular health and that’s because they are giving a partial estrogenic effect in the liver. This is allowing them to potentially improve the lipid profiles as well as to offset some of the negative effects of the androgens either.

With the doses that are as high as 600 mg or less of testosterone per week, the impact on the lipid profile, although is still noticeable, is definitely not dramatic and that’s why, in most cases, an anti estrogen (for cardio protective reasons) is most likely unnecessary. Even though there are people who might still need it, usually – more sensitive individuals.

In addition to that, doses of 600 mg per week or less than this also have failed to give any statistically significant changes in the LDL/ VLDL cholesterol, in the C reactive protein, triglycerides, apolipoprotein B/C-III as well as insulin sensitivity, all of which is indicating a pretty weak impact on the cardiovascular risk factors, although they still shouldn’t be excluded. When the steroid is being used in moderate doses, the injectable testosterone esters are most commonly thought to be the safest of all the anabolic/ androgenic steroids out there.

In order to help to reduce the cardiovascular strain, it is being recommended to start having a cardiovascular healthy lifestyle. This includes a cholesterol friendly diet as well as to keep an active cardiovascular exercise program. Usually, this is not an issue for those searching for steroids for physique and performance enhancing reasons but except for exercise program, a cholesterol friendly diet is exactly as important.

Here includes: minimize (or completely exclude if possible) the intake of saturated fats, cholesterol as well as simple carbohydrates. In the same time, it is important to supplement with omega fatty acids (fish oils – 4 grams per day at least) as well as to add a natural cholesterol/ antioxidant forums to your diet, a good example is Lipid Stabil but you could also add anything else that has comparable ingredients to this product.

Keep in mind that both the cardiovascular exercise program as well as the diet should be kept at all times during the active administration with Sustaxyl or any other steroid you’re on. This would greatly reduce the risks of cardiovascular diseases and cholesterol issues. If you have any of these issues before starting using any steroids, it is recommended to avoid the administration of any of them.

Testosterone Suppression Side Effect of Sustaxyl 350 (Sustanon)

It is very well known that every anabolic or androgenic steroids that are being used in doses that are enough to offer muscle gain are being expected to suppress the natural endogenous testosterone production. Testosterone is the main male androgen and is offering some pretty strong negative effects on the endogenous testosterone production.

The testosterone based substances, will, likewise, have a pretty strong effect on the hypothalamic regulation of the natural steroid hormones. By not offering an intervention of the testosterone stimulating substances, the testosterone levels should return back to normal within a period of 1 to 4 months after the drug has been discontinued.

However, it can sometimes last to a year or so. This doesn’t apply if the pre use levels were already low. The users are recommended to include a Post Cycle Therapy (PCT) plan in order to make the testosterone levels return back faster and therefore to have a better/ faster recovery. It is important to note here that the prolonged hypogonadotrophic hypogonadism can occur thanks to steroid abuse and this is going to necessitate medical intervention.

Sustaxyl (or Sustanon) will suppress natural production but since it offers testosterone, it is obvious the user won’t fall into low testosterone condition. This might occur after the drug would be discontinued since the natural testosterone production is going to be greatly suppressed and that’s why is important to implement a PCT plan.

General Administration of Sustaxyl 350 (Sustanon)

Very often it is said that testosterone propionate is being regarded as a painful injection. As it has been discovered, it is due to the very short carbon chain of the propionic acid ester and this can be irritating to the tissues at the injection site.

For this reason, a lot of the sensitive individuals decide to completely avoid using this steroid since their bodies are negatively reacting to it with a really bad soreness and low grade fever that can last for some days after each administration with the injection.

Administration of Sustaxyl 350 (Sustanon) for Men

In order to treat the androgen insufficiency condition, the prescribing guidelines for Sustaxyl 350 is calling for a dosage of 250 mg every 3 weeks. Even though this product is considered to be active in the body for a longer period of time, Sustaxyl 350 is usually being injected every 7 to 10 days for the muscle building reasons.

People decide to administer it more frequent compared to how much time is active in order to keep stable levels. This is the schedule that would allow for the higher doses most commonly be applied by athletes and also more stable elevations in the hormone level. It is said that the common dosage among the male athletes is in the range of 250 mg to 750 mg per injection and is being taken in cycles anywhere between 6 to 12 weeks in length. As much as it has been noticed, this dosage is just enough for the most users to start having amazing gains in the muscle size and strength. It is obvious that the higher the dose the better the results, but this dosage is considered safe enough while offering benefits enough.

As it was said, you won’t find Sustaxyl 350 a good steroid for cutting cycles, however it is being most commonly used into the bulking phases of training, in the time when the added water retention is going to be of a little consequence, for the individual who is being more concerned to get raw mass than definition.

Nevertheless, there are still some rare situations where people are using this steroid into the cutting phases either, however usually it is being used in much lower doses (for example, the most commonly known dosage protocol for this purpose is 125 to 250 mg every 7 to 12 days) and/ or when it is being accompanied by some aromatase inhibitor in order to keep the estrogen levels under control, otherwise Sustaxyl is going to offer effects that are not suitable for cutting cycles. Also Sustaxyl 350 is considered to be an extremely effective anabolic substance and that’s why  is often being used alone with amazing benefits either.

However, on the other hand there are some users who would find the need to stack it with some other anabolic or androgenic steroids in order to get a stronger effect, like for example, in this case an additional of 200 to 400 mg per week of boldenone undecylenate, nandrolone decanoate or methenolone enanthate should be enough to offer some noticeable benefits/ results while having no significant hepatotoxicity and generally keep the side effects low. But then again, this depends on each individual’s sensitivity. In the end, testosterone is considered to be very versatile which is great as it can be combined with a lot of other anabolic / androgenic steroids in order to pursuit the desired effects/ results.

There are some bodybuilders out there that have been known to use some really high doses of this steroid (excessively – they went to 1000 mg per week or even more than that), and that’s even though this type of practice is generally not being recommended. That’s because there are few individuals who can well tolerate such a dosage, if any. That’s all because at the dosage that are above 750 mg per week, the water retention is most likely going to account for more of the additional weight gain than the new muscle tissue. With this being said, such doses are more detrimental without further benefits.

Generally, the practice of “mega dosing” is considered to be inefficient (and not to mention that is also dangerous) as anything that is abused is dangerous, and especially when we are talking about anabolic/ androgenic steroid. That’s especially when we are going to consider the fact of typical high cost of Sustaxyl 350. Most commonly, this type of practice is simply not being justified outside of aggressive bodybuilding regimens.

Administration of Sustaxyl 350 (Sustanon) for Women

Sustaxyl 350 is a steroid that’s very rarely used with women in clinical medicine and that’s for good reasons. There are much safer alternatives for women. For all these reasons, it is not being recommended to use this product for physique or performance enhancing reasons either. Women should search for other alternatives, or that’s what it is being recommended.

However, when Sustaxyl 350 is being applied, it is most often used in order to induce masculinization in female to male transsexuals. If that’s an effect that’s not desired by a woman, Sustaxyl 350 should be avoided. It is not recommended to use it for physique or performance enhancing purposes for women because of its really strong androgenic nature, high tendency to produce virilizing side effects as well as slow acting characteristics (which is making the blood levels pretty difficult to control).

Women are recommended to avoid Sustaxyl 350 and find safer alternatives.

Why Buy Sustaxyl 350 | Where to Buy Sustanon?

Although this product is not recommended for women as they might get “virilizing – masculinization” effects, Sustaxyl 350 is an anabolic steroid that can be really helpful for men. Generally, the product is rarely used for cutting cycles but it can be extremely beneficial for bulking phases of training.

It is made out of 4 different testosterone esters and this makes it a great product for those who need to elevate their testosterone levels. It can offer side effects, but they can be controlled with moderate use and knowledge of how to avoid the side effects and keep them under control. Sustaxyl 350 is among the top list of most used steroids and I guess that’s for a good reason. Buy Sustaxyl 350 from Kalpa Pharmaceuticals and you won’t regret it.
