Third-party testing

Publishes COAs
Third-party lab
Not consistently named on COAs
Batch-specific COAs
Verification codes

Supplier claims HPLC and MS testing at 99%+ purity, but many COAs do not name the specific testing lab. Some COAs appear to repeat across batches. Mass-spec data is not consistently provided.

Strengths

Arguably the broadest catalog in the category (peptides + SARMs + ancillaries). Strong brand recognition. Highest confirmed commission rate (20%) in our survey.

Concerns

Affiliate Terms of Service include explicit coupon-site ban with commission forfeiture and a brand PPC bidding ban with forfeiture penalty — language that gives the program unilateral discretion to terminate editorial-adversarial sites. COA transparency gaps: some COAs recycle across batches and do not name the specific testing lab.
