Sostanon 250 is the Mexican version of Sustanon 250 manufactured by Organon. Sostanon is in great demand because it comes in a "preload" 1 mg/ml, 250 mg Testosterone blend. This preload is considered safe because, until recently, counterfieting of such was non-existant due to the expense involved in counterfeiting the packaging. Unfortunately, the rise in the price of legit Sostanon is making it increasing profitable for counterfeiters to promote their versions of Sostanon and counterfeits are becoming abundant. 

Sostanon 250 Price: $10.50-$12 in Mexico, $15-$25 on the black market
