How can we help?

All major credit and debit cards — Visa, Mastercard, American Express, and Discover. Every transaction runs through a secure, encrypted payment gateway.

Orders can be changed or cancelled within 1 hour of placing them. After that they enter processing and can't be modified. Email support@aminobay.com right away with your order number and we'll do our best before it ships.

Declines happen for a few reasons. First, make sure your billing address matches your card exactly. If it persists, try a different payment method or contact your bank to authorise the transaction. You can also email us and we'll help troubleshoot or offer alternatives.

Everything ships in discreet, unmarked packaging with each vial securely cushioned to prevent damage in transit. Our peptides are lyophilized (freeze-dried), so they stay stable at ambient temperature during standard US shipping.

We're sorry about that. Email support@aminobay.com right away with your order number and photos of the issue — photo evidence is required for all claims. Once verified, we send a one-time replacement within 24 hours at no cost (one replacement per order, subject to review).

Every peptide is made to a 99%+ purity standard, and each lot is tested by an independent lab using HPLC (purity) and mass spectrometry (identity). The exact numbers for your lot are on its Certificate of Analysis — scan the QR on the vial or check the product page.

Store lyophilized (powder) peptides at -20°C for long-term storage, or 2–8°C (refrigerator) for short-term use. Keep them out of light and avoid repeated freeze–thaw cycles. Once reconstituted, refrigerate and use within the timeframe noted for that peptide.

Lyophilized peptides keep for 2+ years when stored properly at -20°C. Each product carries a lot-specific date on its Certificate of Analysis.

Our research peptides are synthesized in US-based facilities following documented quality procedures, and every lot is independently tested before it's listed. Orders ship from the US.

Yes — every lot is tested by independent, accredited laboratories: HPLC to verify purity and mass spectrometry to confirm identity. Results are published as a Certificate of Analysis on each product page, and the QR on your vial opens the report for your exact lot.

Every vial carries a QR code — scan it to open the batch-specific Certificate of Analysis (COA) for that exact lot, confirming purity, identity, and quality. You can also view the COA on each product page or in your aminobay dashboard (COA vault). Questions about a COA? Email support@aminobay.com.

COAs are on each product page, and every vial has a QR code that opens its exact lot's report. To see your order's lot-specific COA, log in to your aminobay dashboard and open the COA vault. Can't find it? Email us your order number and we'll point you to it.

We reply to every email within 24 hours on business days (Mon–Fri, 9am–6pm EST). For urgent order issues, put your order number in the subject line for priority handling.

We can't provide medical or therapeutic advice, but our team can help you understand the specifications, purity levels, and research applications of our peptides. Email us your research focus and we'll point you to the relevant product data and published studies.
