Actually, to be quite honest, i haven't been able to really come up with too many cons... As far as i can tell, S4 is legal for research use, correct? No pins, no PCT required, as the pharmokinisis doesn't show any type of suppression or liver damage. I guess one con would be the chance of prostate enlargement if taken at a super high dose..and of course another con: can't seem to find it ANYWHERE! SARM-x or SARM xfactor certainly isn't the real deal, lol. The main question i want to clear up is what kind of GAINS are people seeing with S4 and at what dosage? 3mgs ed? 3mgs @ 4x ed?
