I mix it up.
Ostarine is nice when cruising

Superdrol and epistle are two of the designers that I think are worth using.

Then AAS is the best and most versatile category.

for bodybuilding purposes, the only AAS one needs in their arsenal to look their best, is test, tren, masteron, eq, and anadrol. all these drugs do something specific for a bodybuilder and his development. other drugs can be played with (npp, dbol, ect.) but the ones i listed do everything one needs and does it the best, imo. whatever yout goal is, if test, tren, drol, mast and/or eq cant get you there then nothing will. of course adding gh is a whole nother ballgame.

id save my money and not spend it on bs like PHs or SARMS. stick to what works and is proven. but most gymrats, who dont make $ off their bodies could really accomplish any minor fitness goal with just test.

Really junior?
This Queation(s) is beyond broad and doesn't make much sense as a whole.
You take different drugs for different results. Those results are affected by diet, exercise, sleep, age, etc. If you want specifics for each drug, spend some time narrowing down your questions and doing some research on each one. Otherwise we just have a mess here. Good luck.
