About Pepti7
The Top 7 Magazine for research peptides. We curate, evaluate, and publish the most comprehensive independent vendor rankings and peptide guides in the industry.
Our Mission
The research peptide market is noisy, unregulated, and full of vendors who prioritize marketing over quality. Researchers deserve better — a single, trusted source that cuts through the noise with honest, independent evaluations.
Pepti7 exists to be that source. We independently evaluate peptide vendors, create comprehensive peptide research profiles, and publish editorial guides that help researchers make informed decisions. No vendor pays for placement. No ranking is for sale.
Everything we do revolves around the number 7. Every list is a top 7. Every vendor is scored across 7 criteria. Every guide delivers exactly 7 key insights. This constraint forces clarity — if we can't distill it to the 7 most essential points, we haven't done the analytical work.
All content on Pepti7 is presented for research and educational purposes only. We do not sell peptides, we do not provide medical advice, and we never make therapeutic claims. Our editorial voice is grounded in published, peer-reviewed literature.
The 7 Criteria
Every vendor in our rankings is evaluated across these 7 criteria. Scores range from 1 to 10, with the overall score calculated as a weighted average.
Purity
HPLC purity levels as verified by third-party Certificates of Analysis. We look for consistent 98%+ purity across the full product catalog, not just flagship products.
Price Value
Cost relative to quality delivered. The cheapest vendor isn't the best value — we evaluate what you get per dollar spent, including purity, packaging, and documentation.
Product Range
Breadth and depth of available peptides. We value vendors who cover major research categories while being honest about what they do and don't carry.
Shipping Speed
Order processing time, delivery speed, packaging quality, and temperature considerations. Research timelines don't wait for slow vendors.
Customer Service
Response time, technical knowledge, problem resolution, and overall professionalism. We test support with real technical questions, not just order inquiries.
Website UX
Ease of finding products, clarity of information, COA accessibility, and checkout process. A well-organized website reflects a well-organized operation.
COA Transparency
How proactively and thoroughly a vendor publishes Certificates of Analysis. Batch-specific, third-party COAs published on product pages is the gold standard.
Why 7 criteria? Seven is enough to capture the full vendor experience without diluting the analysis with marginal factors. Each criterion maps to a real decision point that affects research quality and researcher experience.
Editorial Standards
Independence
No vendor pays for placement in our rankings. Our revenue comes from affiliate relationships, but our editorial judgments are independent. A vendor can be our top affiliate partner and still receive a critical review if their quality doesn't meet our standards.
Research Framing
All peptide information is presented within a research context. We reference published, peer-reviewed studies and clearly distinguish between in vitro, animal, and human research findings. We never make therapeutic claims or suggest compounds for human consumption.
Transparency
Our methodology is published. Our criteria are defined. When we update rankings, we explain why. We believe the best way to earn trust is to show our work.
Continuous Evaluation
Rankings are not static. We re-evaluate vendors quarterly, place test orders, verify COAs, and monitor community feedback. A vendor's position in our rankings today reflects their current quality, not their historical reputation.
