Hey guys I just got a quick question for you guys! I am currently running into my 8th week of test E @ 600mgs a week every 3.5 days 2x a week! My question is this... My source doesnt have the same manufacturer as the current test that I am running and was wondering if switching would make a difference as long as its the same compound and I run the same mgs per week. I know this might be a stupid ? but I just wanna make sure before I make my purchase!! Let me know guys!!
