Vetted sources

Where to buy — our vetted sources

This is not a comprehensive vendor directory. It's a short list of sources we've personally vetted. Here's the deal, stated plainly:

Vetted means we reviewed the vendor's published COAs and have ordered from them ourselves. OHM does not lab-test products and does not sell or handle any compound.

Affiliate disclosure: OHM may earn a commission on purchases made through the links or codes on this page, at no extra cost to you. That commission funds this site. It does not change what we publish about any compound.

① These are affiliate partnerships

Every vendor below gives us an affiliate link or coupon code, so we may earn a commission if you buy through them — at no extra cost to you. We're telling you that up front, because radical transparency about our commercial ties beats pretending we have none.

② We only list vendors that clear this bar:

  • Publishes batch-level third-party Certificates of Analysis
  • States domestic manufacturing or accredited third-party testing (vendor's claim — OHM does not audit facilities)
  • Responsive customer service in our own orders

Everything sold by the vendors below is labeled research-use-only and not for human consumption. Nothing on OHM changes that labeling.

US Pure Peptides Vetted · OHM20

US Pure Peptides (West Palm Beach, FL) states that every batch is tested by ISO 17025-accredited third-party labs and publishes a COA with each order. Vendor claims are the vendor's; OHM has not audited their testing.

Code OHM20 at US Pure Peptides takes 20% off.

Supplies + supportive supplements

Everything else you need — from Amazon

The peptides come from the vetted vendors above. The injection supplies and supportive supplements that go alongside them are easier to get from Amazon — same affiliate-disclosure deal. You pay Amazon's price (no markup), and a small commission supports this site.

Injection kit — what's commonly used

One thing you DON'T buy on Amazon: bacteriostatic water. Order it directly from your peptide vendor (Alyve carries it). That's the simplest way to get pharma-grade bac water and it ships with your peptide order.

Supportive supplements — the foundation under specific peptide protocols

These aren't mandatory — they're targeted to specific peptide use cases. The Protocol Builder will tell you exactly which ones apply to your stack.

Not sure which of these apply to your stack? Run the Protocol Builder — it summarizes the supplies and adjunct supplements commonly reported alongside the peptides you're researching.
