Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Ascend Amino. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
01
Where each vendor is stronger
Computed from the rubric, prices and review record — never curated
Purgo Labs
Names its testing laboratory — SteriGenix and Freedom Diagnostics named per lot
Certificates verifiable at the lab, not just the vendor — Verify-at-lab links to sterigenixanalytical.com / freedomdiagnosticstesting.com
Batch-specific COAs matched to lots — Lot numbers (e.g. PL-BPC-05) with test dates per batch
Publishes measured net content vs label — Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
COAs and pricing viewable without an account — COAs on product pages without login
Independent review base (50+ on an external platform) — 4.7 / 99 on Trustpilot (re-read 2 Oct 2026; was 4.7 / 95 on Trustpilot)
No contradictions among its own claims — No contradictions found across site claims (checked Aug 2026)
Only vials both vendors list at the same size, read on each vendor's product page on the date shown. "After code" is list × the code's stated discount — a calculation, labelled as one; stacking with sale pricing is not cart-tested.

What we found at Ascend Amino
Read 5 September 2026 on the vendor's own pages
We cannot tell you anything about Ascend Amino's testing because Ascend Amino will not show it to you until you register. That single design choice removes five of our ten criteria from play. Prices are clear and the review record, at 39, is small but positive. Treat the 'third-party tested' claim as unverified until you have an account and a certificate in front of you.

Could not verify · flags
?Anything about the certificates — the COA link redirects to an account-registration form, so the lab name, lot numbers and net content cannot be checked before buying.
?Address or phone — none on Terms, Contact or FAQ; email only.
?What 'AA - 1SM' and 'AA - 3RT' are — the vendor never states the compound.
!The Terms page names the company 'Ascend Supply Group LLC' in some clauses and 'ASCEND LLC' in others.
!Certificates gated behind account creation — the homepage says 'Certificate of Analysis available for every batch' but you cannot see one before you register.
!Brand-confusion cluster: several unrelated vendors trade as 'Ascend ___'; at least one Trustpilot reviewer of this site calls it 'Ascend Bio Labs'.
!Site blocks non-browser requests; everything here was read in a normal browser session.
Ascend Supply Group LLC d/b/a Ascend Amino · 2108 N St STE N, Sacramento, CA 95816 — both in the Terms (read 24 Sep 2026; the entity was also written 'ASCEND LLC' on the same page in Sep 2026) · cs@ascendamino.net
Ascend Amino appears in 2 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-062/10 — re-issued under rubric v2 (was 1/8); not awarded: named-lab, lab-hosted, per-lot, net-content, ungated, review-base, claims-consistent, identity
2026-09-243/10 — 2/10 → 3/10 — identity awarded: Ascend Supply Group LLC d/b/a Ascend Amino with a Sacramento street address, both on /terms-conditions/
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Ascend Amino: the caveat
The COA page redirects to account registration — certificates cannot be viewed before purchase, so lab name, lot matching and net content are all unverifiable from outside. 39 reviews. No address or phone. GLP products sold as 'AA - 1SM' and 'AA - 3RT' with no stated identity. The Terms name the company two different ways.
