The Optimal Health Manifesto
Verified sources

Where to buy — our verified 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:

When you use my coupon code to buy peptides with these sellers, you enjoy a discount off retail price, and I make a small commission which helps me to continue to offer this peptide educational site to you for free. I only have affiliate relationships with peptide manufacturers that show evidence that their peptides are 100% manufactured in the US, 3rd party lab tested for purity, transparent COAs posted on their websites, and that have good customer service.

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:

  • Highest-quality research-use-only (RUO) material
  • 100% US-manufactured
  • Heavy third-party lab testing with published Certificates of Analysis (COAs)

Supplies + supportive supplements

Everything else you need — from Amazon

The peptides come from the verified 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 you actually need to inject

One thing you DON'T buy on Amazon: bacteriostatic water. Order it directly from your peptide vendor (Alyve and BioLongevity both carry 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 walks you through the peptides you're running and surfaces exactly the supplies and adjunct supplements that match.
