Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Nova Peptides. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at Nova Peptides
Read 29 September 2026 on the vendor's own pages
Nova's certificate chain checks out at the lab, its prices are open and its LLC is named — the same shape as most 8/10 vendors here. It loses the identity point for having no address and the claims point for an accreditation it asserts but does not evidence. A young vendor with a good vial record and a thin company record.

Where Nova Peptides ranks by compound
Nova Peptides appears in 2 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-298/10 — first assessment (rubric v2); not awarded: claims-consistent (unevidenced ISO/IEC 17025 claim), identity (LLC named, no address) — lab search code confirmed at the lab
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Nova Peptides: the caveat
No street address anywhere — an email only, 'phone support launches soon'. The site says every batch goes to an 'ISO/IEC 17025-accredited laboratory'; the lab on the certificates, Freedom Diagnostics, states no accreditation on its reports and none is cited, so the claim is the vendor's. Cloudflare challenges some visitors. A 15%-off welcome code and a $150 'guarantee' are marketing, not evidence.
