I had to make an account just to reply to this. IRC.bio is g2g and I’m actually curious where you got your mixed reviews from? They have very extensive testing of their product and are highly regarded on reddit. I have personally taken their s-4 and stopped because of vision sides.
I have never heard 1 bad thing about irc.bio. Believe it or not there are other companies with 99%+ purity and not just Dylan pushing expensive sarms and calling everything else fake lol.
