Sarms stack together extremely well.
Running osta and GW is mostly a performance/endurance stack. I found (for me anyways) my HR went up 10 beats within a day from osta.
GW is stealth kick in the ass.
There are additional things you can stack that have additional benefits.
If you are looking to add lean muscle and strength, add S4. Want more muscle, add rad140. Wanna seriously kick ass, add LGD.
Sarms stacked are the only way to go, its matter of what you want out of it, and how much you wanna pay to do it.
Just for an example, my first cycle of lgd/rad/osta/gw amounted to almost 12 pds of muscle, and thats to an old guy at 59 years old. I did this as a bulk. Had I known then about the
synergy of S4 and LGD, I would have added it as well.
My upcoming cycle is a recomp using lgd, S4, Osta, Rad, GW and SR (for fat loss). I've hired a nutritionist to help me with my recomp after reading Dylans words of wisdom on recomps.
You've come to the right place, only use sarmsx (site sponsor), other stuff is bunk or prohormones (seriously no bueno).
