How We Scored Vendors
Our methodology evaluated 47 peptide suppliers across multiple categories over 8 months of testing. Here's how the rankings were determined:
Testing Protocol (100-Point Scale)
- Product Quality (35 points) - Third-party COA verification, purity testing (HPLC/MS), batch consistency, sterility standards, proper reconstitution
- Reliability (25 points) - Order fulfillment rate, shipping times, package arrival rate, product availability, customer service response
- Pricing Value (20 points) - Cost per mg of active peptide, bulk discounts, shipping costs, hidden fees, refund policies
- Safety & Legitimacy (15 points) - Business registration, payment security, data privacy, legal compliance, communication transparency
- User Experience (5 points) - Website usability, ordering process, packaging quality, documentation provided
Real-World Testing
We placed 127 orders across all vendor categories, sending samples to independent labs for verification. We tracked shipping times, communication quality, and actual product performance versus advertised specifications.
Community Validation
Cross-referenced our findings with 400+ verified user reports from research communities, testing logs, and third-party testing results. Excluded vendors with multiple scam reports or serious quality concerns.
Key Takeaways for 2024
- Quality beats price - The $30 you save on cheap peptides can cost you months of wasted protocols with underdosed or contaminated products
- Domestic sources dominate reliability - International suppliers offer value but add 2-4 weeks shipping and seizure risk that many find unacceptable
- Third-party testing is non-negotiable - Vendors providing independent COAs (not just manufacturer certificates) consistently scored 20+ points higher
- The middle tier offers best value - Value-tier US sources (#2 ranking) provide 90% of premium quality at 60% of the price for most common compounds
- Avoid the bottom tier entirely - Social media coaches and random marketplaces showed 70%+ failure rates for quality, delivery, or legitimacy
- Specialty compounds require specialty vendors - For rare peptides, paying premium prices (#4 ranking) is often your only legitimate option
- Medical supervision has value beyond legality - While expensive, peptide clinics (#7) provide protocols and monitoring that can prevent costly mistakes
- Community sources are high-risk, high-reward - Strong networks provide good value, but newcomers have no way to verify trustworthiness
