- Batch-specific COAs

Third-party reviewers report Janoshik-verified COAs for 23+ peptides plus heavy-metal testing. One of few suppliers whose COAs include Janoshik verification codes usable for independent validation.
Strengths
Operational excellence: widest payment menu in the category, 4.8/5 Trustpilot with ~93% five-star from 279+ reviews, free USPS Priority shipping over $200 with same-day processing, Janoshik-verified COAs. Strong operational foundation despite short operating history.
Concerns
Short operating history (founded 2023) means less track-record data. No public affiliate program found — would require direct outreach and custom terms.
