So you can't tell the difference between test prop and tren by just looking at it? I will say that LM seems pure every time, but never had it tested. I've had different test e from different suppliers over the years and what I used to get years ago smelled way stronger and melted easier at room temp (not melting point test) than what I get theses days from multiple suppliers. I'm not sure if the processing is different now but I'm pretty sure it's a basic drug to make and cheap too so why step on it just to make a few extra bucks. I've tried PP years ago and the products seemed legit, got big and strong as fuck. I think most suppliers from china are legit but have always heard high priced items like var are either stepped on or actually another cheaper drug all together and I stay away from those products. I wasn't very impressed with masteron, was expecting some aggression mixed with hard dry gains but I bailed on it after about six weeks.
