i have aquired about a years supply of test c if i only take one ml per week. of 200mg/ml which ive heard is a decent amount if you want to make some good gains. ive been more than satasified with the results thus far but i was wondering what otc stuff may help to enhance its effects as well as anything not otc( black market) but i prefer otc because its just a lot easier to get out here in my neck of the woods. i appriciate any advice that i can get on this matter
