A vetted directory, not a marketplace.
We don’t sell peptides. We rank the people who do, on the criteria that actually matter for your safety: where their lab is, whether they publish third-party tests, and how they treat customers.
Four standards. No exceptions.
Sellers must operate or contract with US-based laboratories with verifiable supply chains.
Every product page must publish an independent certificate of analysis showing identity, purity, and concentration.
A real address, a real customer-service channel, and a written returns policy. No anonymous Telegram-only operations.
A seller’s ranking on this site reflects editorial diligence, not commission rate. We disclose affiliate relationships on every page.
Top three sellers we stand behind today.
These vendors clear our four standards, publish third-party COAs, operate from verifiable US-based facilities, and run affiliate programs we’ve evaluated for transparency.
Limitless Life Nootropics
The most rigorous third-party testing program of any seller we vetted. Independent verification through Janoshik and MZ Biolabs, every batch documented. Florida-based facility with a transparent supply chain. The benchmark for what we mean by "American-sourced, third-party tested."

Chemyo
The QR-code system is the most transparent verification method we have seen anywhere in the research-peptide space. Every bottle links to a batch-specific lab report. Their narrower catalog is a feature, not a bug — they only stock what they can stand behind.
- US labs

- COAs
- Every batch, QR-coded

Core Peptides
The most beginner-friendly experience in the space — clean site, easy navigation, fast US shipping. The tiered commission program (up to 20%) is generous, and our editorial diligence has not turned up red flags despite the shorter operating history.

Sellers worth knowing about.
These vendors meet a meaningful subset of our standards. They didn’t make our top three, but each has clear strengths we’ll continue to monitor.
Modern Aminos
Strengths. High transparency, strong presence in performance research.
Caveats. Stock levels fluctuate on high-demand items.
Sports Technology Labs
Strengths. Known for high stability and purity, excellent customer support.
Caveats. Marketing skews heavily toward fitness/SARMs audience.
Amino Asylum
Strengths. Lowest pricing in the market, broad catalog including niche compounds.
Caveats. Does not publish COAs for every batch. Customer support is minimal.
Pure Rawz
Strengths. Massive inventory including rare research chemicals; QR-code COA system.
Caveats. Frequent shipping delays; international sourcing raises supply-chain transparency questions.
Affiliate disclosure. Some links on this page will become affiliate links once Peptide Intel finalizes its vendor partnerships. If you click through and purchase, we may earn a commission at no additional cost to you. Commission rates do not influence rankings — verdicts are determined by lab quality, COA transparency, and editorial diligence. Sellers that fail our standards do not appear here, regardless of what they offer to pay.
