Amino USA Review (September 2026): What the Texas Vendor States, What Is Verified

Amino USA is a Texas-based research-compound vendor that, like several names the Bureau has reviewed this month, exists on two domains at once. Aminousa.com is a Shopify-style store that says the company "was started to ensure researchers are getting what they paid for" and has shipped "60,000+ orders to researchers around the United States". Aminousa.us.com is a larger store under the same name and logo that gives an Austin address, a California phone number, a 105-item catalogue and a shipping policy that names a Houston warehouse. The two share products and prices down to the cent, and neither page the Bureau read mentions the other.

Both sites were live and taking orders in the first week of September 2026. Amino USA is not one of the five vendors on the Bureau's 2026 vendor scorecard, which weighs documentation, consistency, shipping and price, and the Bureau has not ordered from either domain, so what follows is a desk review built from the vendor's own pages, one domain-registration record, one removed review profile and the FDA's public database.

What Amino USA is and which site is which

Aminousa.com. The home page states that products come from "WHO/GMP and ISO 9001:2015 approved manufacturers" and that the company confirms "the purity of our products through third-party testing". It gives no address, phone number, email or entity name on the pages the Bureau could read; the FAQ, about, shipping-policy and refund-policy URLs all returned 403 errors to the Bureau's fetcher. A ScamAdviser record for the domain, fetched the same week, shows it registered on 25 July 2023 through Dynadot with WHOIS ownership hidden, hosted behind Cloudflare in the United States. The catalogue spans peptides, bioregulators (Bronchogen, Cardiogen, Cartalax, Chonluten and Cortagen at $45.00 to $50.00), nootropic powders (Aniracetam, Fasoracetam from $16.00) and research chemicals (Agomelatine $40.00, Enclomiphene $55.00).

Aminousa.us.com. The footer gives 5900 Balcones Drive Suite 100, Austin, TX 78731, a +1 (310) phone number and [email protected]. The shop lists 105 products in categories the site calls Aminos, Bioregulators, Modulators, Neuroactives and Peptides, advertises "Fast & Free Shipping on All Orders" and a 10% code, AUSA1, and states that it runs "third-party verification across three separate labs" using mass spectrometry for identity and HPLC for purity with a minimum of 98%. Its shipping policy, however, describes fulfilment "from our Houston, Texas warehouse" and charges for shipping, which the Bureau returns to below.

The PeptideMind directory, in a profile it says it last verified on 19 June 2026, gives aminousa.com as the official URL, Houston as the location, and names MZ Biolabs and BioRegen as the laboratories, with a QR code on each vial linking to the batch certificate. The Bureau reports that as the directory's description; it did not see those lab names on either Amino USA site.

What the vendor states about testing and COAs

Across the two sites the statements are consistent in substance. Aminousa.com's home page says purity is confirmed through third-party testing at approved manufacturers; its BPC-157 product page adds ">98% purity", "batch & lot tracking tied to publicly posted lab reports", and "independent third party laboratories", and gives the CAS number, molecular weight and a storage instruction of 6°C or below. Aminousa.us.com's home page says "Third-party tested for profile, purity, and mass" across three labs, with HPLC purity of at least 98% and concentration verification, and that certificates of analysis are accessible. The all-products page on aminousa.com marks "Certificate of Analysis" documents as available for most items.

What the Bureau could not do is open one. No certificate link, image, lab name, batch number or test date was visible on the BPC-157 page or the collection pages the Bureau retrieved, and the research page that appears in search results as the lab library returned a 403. So the practice is stated, and the vendor says the reports are public, but the Bureau cannot report a single purity figure, lab name or date from an Amino USA certificate and has seen no independent retest of an Amino USA vial. Compare the certificate the Bureau opened for Direct Peptides on the Direct Peptides review, which carried a lab name, two dates, a method and a number; that is the standard the peptide testing guide asks for.

Prices, with the scored vendors alongside

Amino USA prices are public on both domains and match where the Bureau could compare them. The peptide collection on aminousa.com listed 23 items; the table takes its figures from that page and the all-products page, with the aminousa.us.com figure noted where it differs. One inconsistency: BPC-157 5mg showed $30.00 on the collection page and $35.00 on its own product page when fetched in the same session. Scored-vendor figures are from product pages fetched in the first week of September 2026; Ascension's are September sale prices with the regular price in brackets.

Other aminousa.com list prices: AOD-9604 10mg $80.00, ARA-290 10mg $50.00, Epitalon 10mg $30.00 and 50mg $130.00, GHRP-2 5mg $20.00, GHRP-6 5mg $15.00, Ipamorelin 5mg $30.00, IGF-1 LR3 $70.00, NAD+ 500mg $125.00 and 1000mg $230.00, Oxytocin 5mg $35.00, CJC-1295 DAC 2mg $25.00; aminousa.us.com also listed 5-Amino-1MQ 50mg at $175.00 and Sermorelin 15mg at $100.00. On the recovery compounds Amino USA sits at or slightly above Apollo and above the Ascension sale and Amino Club floor prices; on GHRP-2, GHRP-6 and Ipamorelin it is cheap in absolute terms. To compare per milligram, the reconstitution calculator does the maths, and the GHRP-6 guide covers what the published data says about the cheapest listing on the page.

Shipping, payment and returns

The only shipping policy the Bureau could read is on aminousa.us.com, because aminousa.com's policy pages were blocked. It states that valid orders are "fulfilled and safely dispatched within 24 business hours", that orders placed before 12:30 PM CST Monday to Friday ship the same day, and that fulfilment is from a Houston, Texas warehouse to domestic US addresses only. Three services are listed: UPS 2-Day Air at $12.75 (free over $250), UPS Ground at $9.75, and USPS Priority Mail at $11.00 for P.O. Box and APO addresses, all subject to state tax. The company disclaims responsibility for parcels lost or delayed through an incorrect address and for parcels marked delivered by the carrier.

That policy sits under a home-page banner reading "Fast & Free Shipping on All Orders". The Bureau reports both statements and cannot tell you which applies at checkout; read the cart total before paying. Neither site's payment methods were visible on the pages the Bureau retrieved. PeptideMind records credit card, cryptocurrency and e-check; that is a directory's report. Return terms were not readable on either domain.

Reputation signals the Bureau could source

Trustpilot. The profile page for aminousa.com does not show reviews. It displays the notice: "The business you're trying to find goes against our guidelines and is no longer visible on Trustpilot." Trustpilot does not state on that page which guideline was involved, and the Bureau does not speculate; the removal is reported here because it is a public fact a buyer would otherwise not find. ScamAdviser's record separately notes "no reviews were found on commonly used review sites" for the domain and flags it, as it does for the category as a whole, as selling prescription-type medicines without a prescription check.

Directories. PeptideMind shows a 4.3 out of 5 from 18 reviews (20% five-star, 40% four-star, 40% three-star). Small sample, third-party.

Regulators and closures. A search of the FDA warning letter database in the first week of September 2026 returned no letter naming Amino USA or either domain. The August 24 2026 letters posted on 1 September went to Peak Performance Peptides, Royal Peptides, NuScience Peptides, Peptide Partners and TXP Innovations; Amino USA is not among them. The name appears on none of the three vendor shutdown lists the Bureau checked. Absence from a search is not a clearance.

Two domains. The Bureau found no page on either site acknowledging the other. They share a logo, a product range and prices, and they disagree on the address (none given versus Austin), the warehouse (Houston in the policy) and whether shipping is free. The fake vendor checklist explains why the Bureau treats a two-domain brand with a hidden WHOIS record as something to pin down before ordering, not something to assume is fine.

The Bureau's honest read

Verified from the vendor's pages: two live storefronts under one name and logo; public prices that match across them; a stated three-lab third-party testing practice with a 98% purity floor; an Austin address and a Houston warehouse on the .us.com site; itemised UPS and USPS shipping tiers with a 12:30 PM CST same-day cut-off; a 2023 domain registration for aminousa.com with hidden ownership.

Not verified: any certificate's contents; the laboratories; the legal entity; payment methods; return terms; whether shipping is free or charged; which domain is the original; and the reason Trustpilot removed the aminousa.com profile. The Bureau has not placed an order.

Who it suits. A US researcher who wants a wide catalogue that runs from bioregulators and GH secretagogues to nootropic powders in one cart, at prices in the same band as the scored vendors, and who is prepared to ask support for the certificate before buying. Who it does not suit. Anyone who wants to see the COA on the product page, anyone who wants a review record they can read, or anyone who needs to know which of two domains they should be typing. The scored vendors below all show the certificate in the open.

Where to buy instead, or as well

Disclosure and a line in the sand. Everything above this heading is about the vendor named in the title. Everything below is about the five vendors the Bureau scores on its 2026 vendor scorecard, and links to them may earn the Bureau a commission. All five operate on a single domain, publish prices without a log-in, and show or link a certificate from the product page.

• Apollo Peptide Sciences: the Bureau's top-scored vendor. Apollo Peptide Sciences LLC gives an Oxnard, California address, states its products are "routinely tested by the most trusted labs" with certificates of analysis available for review, ships by USPS Priority or Express within 48 hours, and on the product pages the Bureau fetched in September 2026 the compound behind each coded GLP name is spelled out (GLP-3 R is identified as retatrutide, GLP-2 T as tirzepatide). BPC-157 10mg was $59.99, free shipping over $200. Full review: Apollo Peptide Sciences review. Check price at Apollo Peptide Sciences
• Pantheon Peptides: the broadest catalogue in the Bureau's top tier, with a Lab Results page that promises every certificate of analysis for each peptide. The US storefront listed BPC-157 5mg at $60, shipping from Canada within 24 hours and free express post over $200 when the Bureau checked. Pantheon Peptides review.
• Amino Club: publishes "From" prices openly (BPC-157 from $39.99, TB-500 from $39.99, GLP-3 (RT) from $69.99, MOTS-C from $39.99) and states every batch is "8x tested by ISO 17025 accredited laboratories", covering HPLC purity, net peptide content, identity, appearance, a fentanyl screen, heavy metals, sterility and endotoxin. Free shipping over $100. Amino Club review.
• Ascension Peptides: under evaluation on the scorecard, but the product pages the Bureau fetched each carry two dated third-party COAs (Kovera Labs and MZ Biolabs) with batch numbers, and September sale pricing was the lowest of the set (BPC-157 10mg $49, R-10 $75, T-10 $80, MOTS-c 10mg $62). Free shipping over $250. Ascension Peptides review.
• Limitless Life Peptides: the long-standing Florida vendor, now trading as Limitless Biotech, with a 91-compound catalogue, COAs stated to be on each product page, and prices behind a professional log-in. Limitless Life Peptides review.

Whichever way you go, the Bureau's how to buy peptides guide and the peptide testing explainer cover how to read a COA before you pay. Nothing here is medical advice; these are research compounds and the Bureau does not advise anyone on using them.

Frequently Asked Questions

Which is the real Amino USA site, aminousa.com or aminousa.us.com?

The Bureau could not settle it from the vendor's own pages, because neither site mentions the other. They share a name, logo, catalogue and prices. Aminousa.com gives no address, phone or email on the pages the Bureau could read and was registered in July 2023 with hidden ownership; aminousa.us.com gives an Austin, Texas address, a (310) phone number and a sales@ email, and its shipping policy names a Houston warehouse. A directory lists aminousa.com as the official URL. Confirm the domain with support before paying.

Does Amino USA publish certificates of analysis?

It says it does. Both sites state third-party testing, aminousa.us.com naming three separate laboratories with HPLC purity of at least 98% and mass spectrometry for identity, and the BPC-157 page on aminousa.com describes batch and lot tracking tied to publicly posted lab reports. The Bureau could not open one: no certificate link, lab name, batch number or date was visible on the product or collection pages it retrieved, and the lab-results page returned an error. Ask support for the certificate for your lot before ordering.

What does Amino USA charge for BPC-157?

In the first week of September 2026 aminousa.com listed BPC-157 at $58.00 for 10mg and $85.00 for 15mg, with the 5mg vial showing $30.00 on the collection page and $35.00 on its own product page. Aminousa.us.com showed the 10mg vial at $58.00 reduced from $60.00. For comparison, Apollo Peptide Sciences listed BPC-157 10mg at $59.99, Ascension Peptides at $49.00 on sale from $74.99, and Amino Club from $39.99 in the same week.

Is shipping from Amino USA free?

The home page of aminousa.us.com says Fast and Free Shipping on All Orders, but the same site's shipping policy lists UPS 2-Day Air at $12.75, free only over $250, UPS Ground at $9.75 and USPS Priority Mail at $11.00 for P.O. Box and APO addresses. The policy also states dispatch within 24 business hours, same-day shipping for orders before 12:30 PM CST on weekdays, and domestic US delivery only from a Houston warehouse. The Bureau cannot say which statement applies; check the cart total before you pay.

Why does Trustpilot not show reviews for Amino USA?

Because the aminousa.com profile has been removed. The page displays Trustpilot's notice that the business goes against its guidelines and is no longer visible on the platform, without stating which guideline. The Bureau does not know the reason and does not speculate. Other sources are thin: a directory shows a 4.3 from 18 reviews, and a domain-check service notes that no reviews were found on commonly used review sites. Treat the vendor as one without a readable public review record.

Has the FDA or anyone else taken action against Amino USA?

The Bureau found no FDA warning letter naming Amino USA, aminousa.com or aminousa.us.com when it searched the agency's database in the first week of September 2026, and the name is absent from the three vendor shutdown lists it checked, the newest dated 5 September 2026. Both storefronts were live and listing products. That is what the Bureau found on the date stated; it is not a clearance, and the FDA's 2026 letters show the agency reviewing vendor websites for claims regardless of research-only labels.
