if you talking about oral winny and it was GTP, the yes you most likely had a very bad reaction because of the piss poor qaulity controlled UG it came from. It it wasn't GTP but some other UG -then same probably applies.
If the oral stanz came from a reputable pharm then its less likely to get acne.
As for gear that won't cause any acne or barely any noticeable sides: Human Grade PRIMO. But don't expect to grow that much.
