A-50 – 50mg 10ml/vial GOLD USA

Hello, how much to inject depends on your level of experience and goals. 1 ml of this product is going to offer 50 mg of Oxymetholone. You need to inject it on a daily basis, and better - split dosage per day. This means that if you want to use 50 mg/day, it's better to use 25 mg in the AM (0.5 ml) and 25 mg in the PM (0.5 ml) for example. There's no ester attached, that's why you can't see it mentioned. That's why it needs to be administered daily. How many vls for a cycle depends on the amount you use. If you use 50 mg/day you need 1 ml. It means that 1 vial is enough for 10 days. Considering that, you need 5-6 vials for a 6-8 week cycle. But you may need more or less depending on the dosage.
Also, I would not really recommend Anadrol to a 50yrs old, especially if you're battling with gyno. Anadrol is liver toxic (even in injectable form) but the problem is that you're very likely to experience gynecomastia from Oxymetholone (Anadrol). And Adex won't help with gynecomastia from Oxymetholone because this steroid doesn't convert into estrogen. You need Nolvadex (Tamoxifen) to deal with gynecomastia from Oxymetholone.
Anyway, for all these reasons, most people go for oral Anadrol pills instead of injections. Although some believe that injection is safer and a stronger version than oral pills - there are no studies to prove that.
