What this page is trying to make easier
The goal is to weigh the genuinely strong public COA library against the payment terms, since the two point in different directions on how much reversibility a buyer has if something goes wrong.
Supplier review
Amino Science review
Amino Science (Amino Science Labs LLC) is a US-based storefront with public pricing, a large public COA library covering roughly 30 product/strength combinations, and same-day shipping before 5pm CT. The catch is checkout: the site's own Terms of Service state that payment is accepted only via Cash App, Venmo, and Zelle — peer-to-peer apps with no card-style chargeback protection, rather than a card processor.

This page is reviewed periodically so the notes stay current on COA library coverage, pricing, and checkout terms.
Why it stands out
Large Public COA Library
The dedicated COAs page lists roughly 30 product/strength listings, each linking to a PDF hosted on an independent third-party lab's own domain (Freedom Diagnostics Testing) rather than only a supplier-hosted file — a stronger setup than suppliers that only describe testing in general terms.
- Broad catalog covering BPC-157, TB-500, GHK-Cu, Semaglutide, Cagrilintide, GLOW/KLOW blends, and more
- Public pricing shown on every product card, no account required to browse
- Same-day shipping for orders placed before 5pm CT; US-only
Buyer fit
Who this may suit
Researchers who are comfortable paying via Cash App, Venmo, or Zelle and want to check batch documentation before ordering from a broad catalog.
Review summary
Where it looks strongest
Documentation coverage is broad and easy to browse without creating an account, and each COA links out to a lab domain separate from Amino Science's own site, which is more checkable than a self-hosted PDF alone.
Trust signals
What the page communicates clearly
A named LLC (Amino Science Labs LLC), public pricing, a clearly written refund policy, and a same-day-ship commitment with a specific cutoff time.
Potential drawback
What to double-check
Per the site's own Terms of Service, payment is accepted only via Cash App, Venmo, and Zelle. None of these carry the buyer-side dispute or chargeback protections a card payment does, so treat the purchase as final once funds are sent, regardless of what the refund policy states.
Ideal buyer
Who this page points toward
Someone who has already vetted the COA library for the specific product they want and is comfortable with peer-to-peer-only payment terms.
Catalog and documentation
What's listed
The catalog spans common compounds (BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, MOTS-C, NAD+, Semaglutide, Cagrilintide, Sermorelin, Selank, DSIP, PT-141, Glutathione) plus blends like GLOW and KLOW, in multiple strengths.
Where COAs live
Published per product/strength, hosted externally
The COAs page lists each product/strength with a direct link to a PDF on a lab-operated domain (Freedom Diagnostics Testing). It's not tied to an individual purchase's lot number the way some suppliers' libraries are, so confirm with support whether a specific incoming batch matches the posted COA.
Payment terms deserve a close read
Cash App, Venmo, and Zelle only — no card processing
The Terms of Service list only peer-to-peer payment apps as accepted methods. All three settle quickly and are difficult or impossible to reverse once sent, unlike a credit or debit card. Combined with the site's all-sales-final policy, this leaves a buyer with limited recourse beyond the seller's own discretion if an order goes wrong.
Refund policy is replacement-only
No refunds after shipment, 48-hour damage window
Damaged or incorrect items are eligible for a free replacement only, not a refund, and only if reported within 48 hours of delivery with photos. Packages marked delivered but not received are treated as a carrier issue, not the seller's responsibility.
Editorial take
Strong documentation, weak payment protection
Amino Science's public COA library is genuinely broad and hosted partly outside the seller's own domain, which is a real positive. But the combination of Cash App/Venmo/Zelle-only payment and an all-sales-final policy is the same pattern that lowers trust for other suppliers in this directory, regardless of how good the documentation looks.
Bottom line
Quick verdict
Worth a look for the catalog and documentation, but go in aware that payment is peer-to-peer only and effectively non-reversible — confirm order details carefully before sending funds.
