We rate Dual Aminos 8/10. PeptidePrices retained nine complete public reports and matched six to exact Freedom Diagnostics records. Five current product-and-strength rows receive verified controls. Tesamorelin 10mg, AHK-Cu 50mg, and GHK-Cu 50mg receive neutral View COA controls because their complete reports and vials identify Dual Aminos, while their issuer lookups returned no document.

Evidence summary
Why Dual Aminos is rated 8/10
Our conclusion
Dual Aminos is an operating US research storefront with nine inspectable public reports, six exact issuer matches, eight current certificate controls, current stock, clear shipping terms, several payment methods, and a verified 15% customer code.
Dual Aminos earns 8/10 from the owner-set factors. Three reports do not resolve in the issuer portal, and the AHK-Cu and GHK-Cu documents share one identifier. Those retained files remain available through neutral View COA controls with the lookup result and conflict disclosed.
Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
COA coverage and verification
Dual Aminos publishes seven certificate figures on its central COA page. PeptidePrices also inspected every gallery on all 17 live product pages and found two additional certificate identities, Retatrutide 20mg and GHK-Cu 50mg. The retained library therefore contains nine complete one-page reports across eight Freedom Diagnostics search codes. Six reports matched exact official records. Five current rows receive exact verified controls: Retatrutide 10mg and 20mg, Tirzepatide 30mg and 60mg, and NAD+ 500mg. Tesamorelin 10mg, AHK-Cu 50mg, and GHK-Cu 50mg receive exact retained View COA controls. Their reports and vial images identify Dual Aminos, but Freedom Diagnostics returned no document for code Dual2604270275 or shared code Dual2604060327. The AHK-Cu and GHK-Cu viewers disclose that shared-code conflict. The April Retatrutide 10mg report remains historical.
PeptidePrices did not establish a mature exact-domain independent customer-review aggregate during the September 14, 2026 review. The storefront product pages showed no customer reviews. The owner set the reputation factor at 6/10; that decision remains separate from the store's laboratory claims.
03
Shipping, payment, and checkout
The live store listed 17 products. 16 comparison-ready rows across 12 product pages have a reliable compound and vial quantity, and all 16 were in stock. The Tesamorelin product gallery establishes the current 10mg vial. Reconstitution solution is excluded. AOD9604, BPC-157, KPV, and MT2 remain outside price comparison because their current pages do not disclose a vial strength. Checkout was limited to the United States and offered card/Stripe, Zelle, and Venmo/Cash App. Shipping was $10 on the tested cart and free over $150. Orders placed by 1 PM Central on business days usually ship the same day, although processing can take one to three business days. Code peptideprices reduced a $49.99 BPC-157 cart by $7.50 to $42.49 before shipping. No order was placed.
04
