How We Ranked the Best Peptide Providers
Finding a trustworthy peptide provider is challenging. The market is filled with providers ranging from legitimate medical practices to questionable online vendors. We created The Peptide List to bring transparency to this space.
Our rankings are based on objective criteria: verified pharmacy relationships, pricing transparency, patient reviews, and quality standards. We don't accept payment for rankings or use affiliate links—our only goal is helping you find legitimate providers.
What to Look for in a Peptide Provider
1. Verified Pharmacy Sourcing
The most important factor is where a provider sources their peptides. Look for providers using 503A or 503B compounding pharmacies. These facilities are regulated and must meet quality standards. Avoid providers who won't disclose their sourcing.
2. Transparent Pricing
Legitimate providers publish their prices or provide clear quotes. Be wary of providers who hide pricing until after consultation or add unexpected fees.
3. Proper Medical Oversight
Peptide therapy should be prescribed and monitored by licensed medical professionals. Look for providers with board-certified physicians or nurse practitioners.
4. Third-Party Testing
Quality providers can show Certificates of Analysis (COAs) from independent labs verifying peptide purity and potency.

Frequently Asked Questions
What makes a peptide provider trustworthy?
Trustworthy peptide providers have verifiable pharmacy sourcing (503A or 503B), transparent pricing, third-party testing with Certificates of Analysis (COAs), proper licensing, and consistent positive reviews from real patients.
Should I use a telehealth provider or local clinic for peptides?
Both can be legitimate options. Telehealth providers offer convenience and often lower costs, while local clinics provide in-person consultations and easier follow-up. The best choice depends on your location, budget, and preference for in-person vs. virtual care.
How do I verify a peptide provider is legitimate?
Check their pharmacy licensing, look for verifiable addresses and contact information, read independent reviews (not just testimonials on their site), ask about their peptide sourcing, and request to see recent Certificates of Analysis.
Why are some peptide providers so much cheaper than others?
Price differences often reflect sourcing quality. Cheaper providers may use overseas peptides with less quality control. Premium providers typically use US-based 503A/503B pharmacies with rigorous testing. Always ask about sourcing before choosing based on price alone.
What questions should I ask a peptide provider before starting treatment?
Key questions include: Where do you source your peptides? Can I see a recent COA? What is included in the consultation fee? How do you monitor patients during treatment? What happens if I have side effects?
