Research peptides, proven batch by batch.
APS supplies lyophilized research peptides at ≥99% purity. Every batch is sent to an independent third-party laboratory for HPLC testing — and the results are published here, next to the batch your order ships from.
All products are sold for laboratory research and development purposes only. Not for human consumption.
NOW SHIPPING — VERIFIED BATCH
The Library
A focused catalog of research peptides. Every listing shows the batch currently shipping — with its measured content and purity — before you order.
Don't see what you need? Other products and other strengths from our supplier's full range are available on request — including additional GLP-1s, growth-hormone secretagogues, and vial strengths not stocked above. Ask through the wholesale & contact form and we'll source it for you.
Built on proof, not promises
APS — The Alpha Peptide Society — was founded on a simple frustration: research buyers were asked to trust purity claims nobody would show receipts for. So we publish the receipts.
Batch testing & purity standards
Every production batch is sampled and sent to an independent third-party laboratory for HPLC analysis covering identity, purity, and quantified content. Our release standard is ≥99% purity — a batch that falls short is rejected, not discounted. The batch code on your vial matches the report on this site.
Fast shipping & real service
Orders placed before 12:00 PM ET ship the same business day, packed to protect lyophilized product in transit, and a real person on our support team answers questions about orders, batches, and reports.
Radical transparency
Measured content, measured purity, test method, and test date — published for every batch, including the ones in our archive. If a number is on a product page, it came off a lab report, and the report is one click away.
Affordability & privacy
Volume and wholesale pricing is quoted per account — no coupon games. Orders ship in plain, unmarked packaging, and your information is used to fulfill your order and nothing else. We never sell customer data.
Test Reports
Every batch of every APS product is sent to an independent third-party laboratory and analyzed by HPLC for identity, purity, and quantification (measured content vs. label claim). Search by product or batch code to inspect the results for the exact batch an order ships from.
Analytical method: high-performance liquid chromatography (HPLC) with mass-spectrometry identity confirmation, performed by an independent third-party laboratory. Reported purity is the measured value for that batch — not a target, not an average.
