Disclosure: Purgo Labs is our affiliate partner, and so is GigaCompounds. 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.

What we found at GigaCompounds
Read 5 November 2026 on the vendor's own pages
Three points are withheld. Checkout takes Venmo, Zelle, crypto and same-day bank payment and nothing a buyer can dispute, and a 5% discount steers you toward Zelle and crypto. The terms name GigaCompounds LLC with Virginia law and a Fairfax County venue but no street address. And although every batch carries a Janoshik report with a verification QR, our lookup at janoshik.com was blocked on 5 November 2026, so the lab-hosted point waits on a completed lookup. The testing itself is the strong part: one report per batch with purity, measured net content, quantitative endotoxin and microbial counts across five vials, a failed batch left on the page, and 65 Trustpilot reviews at 4.8. GigaCompounds is an affiliate partner of ours since 5 November 2026, read the same day; the score does not read that.

Two-page PDF served from gigacompounds.com (ordered 18 May, received 20 May 2026). 11.89 mg is the net content printed on the lab card; the lab-tests card also prints 1.875 EU/vial endotoxin and TAMC/TYMC pass. Page 2 is the Janoshik test report with a QR verification code we could not run on 5 Nov 2026 (janoshik.com blocked the lookup), so verifyUrl is left empty until it completes.
Where GigaCompounds ranks by compound
GigaCompounds appears in 18 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
5 Nov 20267/10 — first assessment (rubric v2); not awarded: lab-hosted (Janoshik QR verification page in the PDF, lookup blocked on 5 Nov; re-run), identity (GigaCompounds LLC, Virginia law, no street address), clean-record (Venmo, Zelle, crypto and same-day bank only; no card rail; 5% off for Zelle and crypto)
Purgo Labs: the caveat
Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
GigaCompounds: the caveat
No card rail: checkout offers Venmo, Zelle (5% off), crypto (5% off) and same-day bank payment only, none of which a buyer can dispute, so the clean-record point is withheld. The terms name GigaCompounds LLC but no street address (Richmond facility, Fairfax County venue), so identity is withheld. The Janoshik report's verification page (page 2 of the PDF) carries a QR code we could not run on 5 Nov 2026, because janoshik.com blocked our lookup; lab-hosted is withheld until that lookup completes. All sales are final; damaged or wrong items must be reported within 48 hours. Several GLP listings are coded (GC-RT, GC-TRZ) and we did not open their reports.

Where to order
Our pick
Purgo Labs 10/10
Certificates checkable at the lab, measured net content per lot, the deepest GLP-1 catalog we track.
Purgo Labs, on the evidence: 10/10 rubric points against 7/10. GigaCompounds is stronger on 3 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is GigaCompounds legit?
GigaCompounds scores 7/10 on our rubric, has an independently viewable rating of 4.8 (65 reviews), and names its lab (Janoshik Analytical). Caveat: No card rail: checkout offers Venmo, Zelle (5% off), crypto (5% off) and same-day bank payment only, none of which a buyer can dispute, so the clean-record point is withheld. The terms name GigaCompounds LLC but no street address (Richmond facility, Fairfax County venue), so identity is withheld. The Janoshik report's verification page (page 2 of the PDF) carries a QR code we could not run on 5 Nov 2026, because janoshik.com blocked our lookup; lab-hosted is withheld until that lookup completes. All sales are final; damaged or wrong items must be reported within 48 hours. Several GLP listings are coded (GC-RT, GC-TRZ) and we did not open their reports.
Which is cheaper, Purgo Labs or GigaCompounds?
On the 12 compound-and-size rows where we have dated prices from both, GigaCompounds lists lower on 5 and Purgo Labs on 7. Purgo's list prices drop 20% with code HEALTH; GigaCompounds's drop with code CR10 (10% off your first order).
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders, as we do from GigaCompounds. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
