Verification Resources
Don't Trust. Verify.
Four ways to know what's actually in your vials — without taking anyone's word for it.
The PeptideSciences collapse was a reminder that even large, trusted vendors can disappear overnight, and their quality documentation goes with them. Independent verification isn't paranoia. It's basic due diligence. Here are the four best options available right now, from cheapest to most rigorous.
Janoshik Analytical
The Gold Standard
Site: janoshik.com
What It Does
Independent third-party HPLC + mass spectrometry. Batch IDs publicly queryable on their own database.
Cost
~$30–$60 per sample
Turnaround
5–10 business days
Best For
Verifying a new vendor before committing to a protocol.
"If your vendor doesn't use Janoshik, ask why. If they say 'we use our own lab,' that's your answer."

Community Batch Testing
Crowd-Sourced
Site: r/Peptides
What It Does
Community members submit independent tests of specific vendor batches. Results posted publicly.
Cost
Free to read. ~$50–$100 to contribute a test.
Best For
Cross-referencing before a new supplier relationship.
"Noisy but useful. Weight posts with more than one corroborating test. One negative result from one anonymous user is a data point, not a verdict."

Eroids Vendor Ratings
Community Intelligence
Site: eroids.com
What It Does
Long-form vendor reviews, lab test postings, community trust scores built over years.
Cost
Free
Best For
Longitudinal vendor reputation — who has been consistent for 12+ months, not just this month.
"The market post-March 2026 is flooded with new vendors. Eroids history predating the Peptide Sciences shutdown is the most trustworthy signal you have."

Telehealth / Compounding Pharmacy Route
The Premium Path
What It Does
Physician-prescribed peptides from licensed 503A or 503B compounding pharmacies carry USP standards and pharmacy board oversight.
Cost
3–10x the grey market price
Best For
Anyone who wants zero regulatory risk and can afford the premium.
"It's the right call for some people. It's also $400–$900/month for semaglutide vs. $120–$250 elsewhere. That math is part of the decision."
