Amino Science Review: Pricing, COAs, Testing, and What We Found

An independent evidence review of Amino Science (aminoscience.io): its public single-vial catalog, regular vs. sale pricing, and a public certificate library whose reports resolve directly at Freedom Diagnostics under the Amino Science client name.

Amino Science is now a curated vendor on PeptideBenchmark. The reason is not a testimonial or a marketing purity banner. It is that the storefront pairs a clean, inspectable single-vial catalog with a public certificate library whose reports resolve directly at the issuing laboratory.

This review separates what we observed directly, what the documents report, what the vendor states, and what remains unverified.

Scope and disclosure. Reviewed August 5, 2026. PeptideBenchmark has no affiliate, coupon, sponsorship, or paid-placement relationship with Amino Science. The vendor sells research-use-only products; this is an evidence and commercial-transparency review, not human-use guidance or medical advice.

The short version

Amino Science (aminoscience.io) publishes a stock-aware catalog of single-vial research peptides and a public /coas library. The August 5, 2026 review found 44 catalog products — 36 single-vial peptides plus 8 multi-product research stacks — and promoted 40 comparable single-vial rows across roughly 32 peptide families onto the PeptideBenchmark pricing board.

On the testing side, the library carried 32 current certificates across 22 products. Every one links directly to a report hosted at Freedom Diagnostics, and PeptideBenchmark confirmed all 32 resolve under the Amino Science client name at the laboratory’s public accession lookup. Average reported purity across those reports was about 99.7%.

Pricing: regular price is the base, sale lanes stay separate

PeptideBenchmark uses each vial’s regular list price as the ranked base. Amino Science runs a sitewide 15% sale and buy-one-get-one-free offers on several vials. Those are real savings, but they are promotional lanes that come and go, so they are captured for context and excluded from the default ranked price rather than silently improving the vendor’s standing.

Multi-product research stacks, bacteriostatic water, the reconstitution kit, nasal sprays, and oral capsules sit outside the retail injectable-vial comparison and are not ranked as peptide vials.

Testing: a provider-verifiable Freedom Diagnostics library

The most useful part of the Amino Science record is that its certificates are not just vendor-hosted PDFs — they link straight to the issuing laboratory. Each library entry points at a Freedom Diagnostics report object, and each report resolves under the Amino Science client name through Freedom’s public accession lookup. That is provider-verifiable evidence, not a logo on an image.

What the reports support:

  • Identity, HPLC/LC-MS purity, and net content for the named sample.
  • An average reported purity near 99.7% across the 32 inspected reports.

What they do not support:

  • Sterility, endotoxin, or heavy-metal results — those panels are not present in these reports, so the storefront’s general purity marketing is not inherited onto them.
  • Blanket, per-strength coverage. Most products publish a certificate per listed strength, which is unusually thorough, but a strength-specific report is evidence for that strength — not automatic proof of every other strength or every future batch.

The coded product names

Two products use coded names. Their certificates settle what they are: GLP-2 TIRZ is tirzepatide, and GLP-3 R (“GLP-3 RETA” on the report) is retatrutide. PeptideBenchmark maps both to those canonical identities so they group and compare correctly.

What we did not verify

  • No physical vial was tested by PeptideBenchmark. A certificate describes the named sample the laboratory received, not the specific unit a buyer receives.
  • The published Fort Lauderdale street line is labeled a mailing address on the contact page; PeptideBenchmark maps that published signal and does not treat it as a verified warehouse or lab HQ. WHOIS remains privacy-protected.
  • Marketing purity claims on the storefront remain vendor-stated except where a linked report actually runs that measurement.

Bottom line

Amino Science earns its curated spot on the strength of an inspectable catalog and a fully provider-verifiable Freedom Diagnostics certificate for each listed strength. The caveats are the ordinary ones for a testing library of this shape: the reports cover identity, purity, and net content rather than sterility or endotoxin, and per-strength certificates are not a substitute for testing every unit.

Common questions

Is Amino Science legitimate?

PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. We confirmed a public storefront at aminoscience.io with a full per-variant product catalog and a public /coas library whose current certificates each link directly to a Freedom Diagnostics report that resolves under the Amino Science client name at the laboratory's public accession lookup. Those facts support an inspectable vendor record, but they do not independently establish the identity, condition, or safety of any physical vial.

Does Amino Science publish COAs?

Yes. The August 5, 2026 review found 32 current certificates across 22 retail products in the public /coas library. Each links directly to a report hosted at Freedom Diagnostics, and PeptideBenchmark confirmed all 32 resolve under the Amino Science client name at the laboratory's public accession lookup.

Are Amino Science COAs independently verifiable?

Yes, for what the reports cover. All 32 inspected reports resolve at Freedom Diagnostics and support identity, HPLC/LC-MS purity, and net content, with an average reported purity near 99.7%. The reports do not run sterility, endotoxin, or heavy-metal panels, so the storefront's purity marketing is not inherited onto panels the certificates do not report.

What are GLP-2 TIRZ and GLP-3 R?

They are Amino Science's coded product names. Their Freedom Diagnostics certificates identify the compounds as tirzepatide and retatrutide, respectively, and PeptideBenchmark maps them to those canonical identities on the pricing board.

Where does Amino Science ship from?

The storefront states same-day shipping on orders placed before 2 PM Eastern and free domestic shipping over $250. The contact page and organization schema publish 201 S Federal Hwy, Fort Lauderdale, FL 33301 as the mailing address. PeptideBenchmark maps that published mailing address as the operating-location signal; it is not an independent PB facility inspection.

Does PeptideBenchmark have an affiliate relationship with Amino Science?

No. At the time of this review, PeptideBenchmark had no affiliate, coupon, sponsorship, or paid-placement relationship with Amino Science.
