20% off with disclosed code
Code benchmark takes 20% off, confirmed at checkout July 17, 2026. It applies after VAYN’s sale prices and its repeating 3-unit and 10-unit block discounts, so the code comes off the already-reduced subtotal.
PeptideBenchmark has a disclosed affiliate relationship with VAYN. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.

Rebranded from His & Hers to VAYN with the same products and formulas. Now at vayn.co with a clean public storefront and a public /coas/ archive — one page per batch. About half the archive is live-verified Chromate (RP-HPLC purity + identity); most of the rest resolves as Freedom Diagnostics provider objects with purity, identity, and net content. Reported purity averages around 99.3%.
Readers who want a rebranded vendor with clean product-page pricing and a public, mostly provider-verifiable purity trail on the new domain.
Rebranded in 2026 from His & Hers — same products and formulas. Prefer batches that carry a Chromate verify link or a Freedom-resolved report, and inspect the tested-panel chips for the exact batch: endotoxin appears on only 4 retained certificates, while no current document reports sterility or heavy metals.
Public COA archive with Chromate and Freedom provider verification
VAYN publishes a public /coas/ index of batch-level pages. 45 retained reports identify Chromate and 40 identify Freedom Diagnostics; 85 certificate origins currently resolve through provider-controlled routes. Most documents report purity and identity, Freedom reports also carry net-content results, and 4 certificates report endotoxin. No current sterility or heavy-metals panel is inferred where a document does not report one.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
