How we work

The incentives, on the table.

Most peptide sites are vendors with a blog attached. We’re the opposite. Here’s what that actually means.

We don’t sell peptides.

We rank vendors who already sell them, by purity testing and policy.

Vendors can’t pay to rank higher.

Order is determined by COA quality, refund policy, and shipping reliability.

We don’t hide regulatory flags.

RUO labels, anti-doping status, and import flags surface on every compound.

We don’t gate the quiz or guides.

Re-run the quiz, browse the library, and compare vendors as much as you want.

What serious users value most

Researchers, coaches, and operators use PeptidePros to compare evidence, spot risks early, and make more defensible decisions.

Finally a peptide site that starts with evidence and red flags instead of pushing random stacks. I can compare options fast without feeling sold to.

Lauren Mitchell

Strength Coach

The vendor notes and compliance warnings are the reason I keep using it. Most sites bury that information or pretend it does not matter.

Kevin Liu

Independent Researcher

I wanted a cleaner way to research recovery peptides without hype. The directory and goal hubs make the tradeoffs obvious.

This feels closer to a decision platform than a store. The risk labels and stack warnings save time and keep the research process honest.

Daniel Chen

Performance Consultant

The best part is seeing what not to combine. Most peptide content online skips that entirely.

Sofia Ramirez

Wellness Clinic Operator

I used the goal pages to narrow the field quickly, then the vendor section to see who actually documents what they sell.

It is one of the few sites in this category that treats regulation, WADA status, and evidence quality like first-class data.

The planner gives me a much better starting point than generic forum advice. It feels structured instead of random.

Ethan Brooks

As soon as I saw the cautions, exclusions, and route notes in one place, I knew this was built for serious research rather than impulse buying.

FAQ

Honest answers, first.

Do you sell peptides?

No. We don't ship, fulfill, or hold inventory. We help you compare what's already out there — vendors who do sell — by surfacing purity testing, refund policies, and regulatory flags side by side.

How do you make money?

Affiliate commissions when you click through to a vendor and buy. Vendors don't pay us to rank higher — order is set by COA quality, refund policy, and shipping reliability.

Is this medical advice?

No. Everything on the site is educational and research-reference only. Not for diagnosing, treating, curing, or preventing disease. Consult a qualified healthcare professional before starting anything.

Is everything really free?

Yes. The quiz, stack builder, compound pages, and the full guide library are free to use. The site is funded by affiliate commissions when you click through to a vendor and decide to buy — not by anything you pay us directly.

What does RUO mean?

Research Use Only. It's the regulatory category most peptide vendors operate under — the products are sold for laboratory research, not human consumption. We surface RUO status on every compound page so you know what you're looking at.

Can I trust the vendor recommendations?

Trust them as one input, not the final word. We weight third-party testing (Janoshik, independent COAs), refund policy, and customer-reported shipping reliability. We don't have inside knowledge of any vendor's supply chain — verify the COA on whatever you receive.

PeptidePros provides educational and research reference information only. This is not medical advice. Not for diagnosing, treating, curing, or preventing disease. Products referenced may be labeled Research Use Only (RUO) by vendors and are not approved for human or veterinary use. If you are subject to anti-doping rules, many peptide hormones and growth-factor-related substances are prohibited. Always consult a qualified healthcare professional.
