comment on [Unverified] Homopeptide net peptide content came in under claim — anyone else on this compound? in c/scamalerts · 78 points · 3 days ago

comment on how many independent tests before you trust a vendor. my number is three. in c/vendorvetting · 167 points · 5 days ago

comment on net peptide content vs purity — two different numbers, same vial, and only one is on your COA in c/coa · 118 points · 5 days ago

Cosigning. The slow route gets the outcome, the fast route gets you the side effects.
