Does the use of trenbolone cause old man face or the abuse of tren?
Also what amount would you consider abuse and what amount be considered conservative?
any heavy androgen use will make people look older. some people are effected worse than others, but tren and then masteron would be the worst. maybe winny too but i don't think i know of anyone who uses winny for more than a couple weeks.
high dose test also fits into the category of a heavy androgenic since it converts to dht.
it's entirely dictated by genetics though, look at pros like jose raymond compared to branch warren. they are all on gh and massive amounts of steroids so it's not their cycle compositions, but genetics that dictates how steroids will effect them.
