I can't tell if this is a serious post or not. Different PEDs do different things.
-Endurance Enhancement - EPO, Candarine
-Strength/Muscular Endurance - Test, Tbol, the steroid list goes on and on. You also have sarms such as Ostarine, these come with the added benefit of increasing mineral bone density whereas steroids lower your collagen. Ostarine and other sarms and also great for injuriy recovery especially muscle belly injuries.
-Recovery, collagen production etc - HGH, GHRP's such as Ipam, Mk-677 (oral ghrp) I have taken, Ostarine and Mk-677 together and felt like I could train multiple times a day, it was truly incredible.
