I have been reading about Clen , i am trying to learn which each chemical does as well as pills so I can understand which does what and which is best for this and that. I noticed clen is majority of the time used for cutting but i keep seeing people asking about a clen/test 3 stack or cycle. What is test 3? i am familiar with test cyp, test prop, and test e. but i cant find exactly what test 3 is for this stack. Someone wanna educate me on it por favor?
