It really depends on how you respond to SARMS. If you're only mildly/moderately suppressed using SARMS you won't need Test and it will be much easier to recover. However if you get suppressed significantly using SARMS I recommend a Test base. Remember suppression varies between individuals and this is something you learn with experience and blood work.
Those are just 3 of the bigger ones but there are a ton of other brands that are out there that are/could be suspect.
I use sarms.forsale personally so i can vouch for them. There may be other legit companies out there when you roll the dice know that more than likely 9 out of 10 companies out there are fake/use compounds other than sarms.
