Research Peptide Supplier Directory
PepPal’s supplier directory lets you compare research peptide stores by testing documentation, COA access, location, shipping terms, payment methods, and current discount information. Open a supplier’s full review for detailed testing, policy, and checkout notes before ordering.
PepPal does not manufacture, sell, or ship peptides. Supplier listings are educational comparisons based on public information, supplier documentation, and independent data when available.
Some outbound links are affiliate links, so PepPal may earn a commission. Paid placements are labeled. Referral pay and discount codes do not decide editorial tiers.

How to read the tiers
The tiers are a practical shortcut, not a guarantee. We rank suppliers by the signals a buyer can actually verify: public COAs, independent testing history, business transparency, checkout reliability, fulfillment, support access, and product-level documentation. Codes and shop links are shown when available, but they are not ranking factors.
Are you a vendor and want to be considered for PepPal? See our vendor partnerships page.
Tier S
Start here first. These are the strongest current fits for most PepPal readers.
Tier A
Strong backups with clear advantages, but not quite the first stop.
Tier B
Useful options when the product fit is right, as long as you verify the batch.
Tier C/D
Context and watchlist suppliers. Read the review before treating them as a real option.
Supplies and research planning
Supplier choice is one part of research planning. Use this short list to keep batch documents, vial details, and basic supplies organized.
