How We Rank Providers
Every provider on this site is evaluated using a transparent scoring system we call the Trust Score. Unlike other directories, we don't accept paid placements and our methodology is fully public.
What We Measure
The Provider Score measures quality and trustworthiness — not what services a provider offers. A high-scoring provider who doesn't offer peptides is still a great provider. Peptide coverage is tracked separately.
4 Categories, 9 Criteria
Clinical Credentials
How qualified the clinical team is.
- 1.5xBoard Certification — Relevant specialty board certifications
- 1.0xYears in Practice — Established track record
- 1.0xCredential Transparency — Bios, licenses, and credentials visible on site
Transparency
How open the provider is with information.
- 1.0xWebsite Quality — Professional site, pricing visible, clear consultation process
- 1.0xPeptide Specialization — How many peptide compounds the provider offers, with confirmation status
Community Visibility
How established the provider is in their community. Low visibility is not a red flag — many excellent clinics are simply newer or smaller.
- 1.0xGoogle Reviews — Rating, volume, and recency
- 0.5xCommunity Presence — Education, social media, events
Compliance
Safety and regulatory checks we perform independently.
- 1.0xPharmacy Verification — Uses an accredited US compounding pharmacy
- 1.0xComplaint History — Clean record with state board and BBB
How Scoring Works
Each criterion is scored 0–10 by our research team (AI-assisted with human review). Within each category, criteria are combined using a weighted average — weights are shown on the badges above. The four categories are weighted equally.
Why scores start around 50
Every provider listed here has already passed our pre-screening — they're licensed, use a US compounding pharmacy, and have a clean complaint record. The Trust Score doesn't ask "is this provider legitimate?" — it asks "how much better is this provider compared to others who already met the bar?" To reflect this, we apply a floor adjustment that compresses raw scores into a ~50–100 range. A score of 55 means a provider passed screening but we have limited data. A score of 90+ means strong signals across all categories.
What the Colors Mean
Each category uses a simple color system to communicate signal strength at a glance:
What About Missing Data?
If we can't evaluate a provider on a particular criterion, it's excluded from their score — they aren't penalized with a zero. Their category score is calculated from available criteria only. This is why newer listings may show lower scores: fewer data points, not necessarily lower quality.
Peptide Coverage
Separate from the Provider Score, we track which of 10 common peptide compounds each provider offers. Each compound is classified by confidence level:
US Compounding Pharmacies Only
We only list providers who source peptides from US-based compounding pharmacies. No gray market, no "research chemical" suppliers, no overseas vendors. If a provider cannot name a US-based compounding pharmacy, they are not listed.
Independence
This is an independent, passion-driven project. No provider pays to be listed or ranked. If sponsorships are ever introduced, they will be clearly disclosed and will never influence rankings.
Data Freshness
Every provider listing shows a "Last verified" date. We regularly refresh our research to keep data current. If you notice outdated information, use the "Report an issue" link on any provider page.
