Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Nexaph. 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 Nexaph
Read 19 September 2026 on the vendor's own pages
The certificate is as good as it gets — a Janoshik report on the lab's own site, four measured vials, batch-matched. The company behind it is a Shanghai entity with no address and a shipping policy that contradicts its homepage, selling in $150+ kits with no returns. Excellent vial, hard-to-reach seller.

Could not verify · flags
?A street address — none on the About, Refunds or product pages read.
?Single-vial pricing — everything is sold as a 10-vial kit, so the per-vial figure ($15.20 for BPC-157 10mg) is arithmetic, not a listed price, and the kit is excluded from our single-vial price index.
?Which shipping policy is current — see contradictions.
!The shipping policy page (effective 20 May 2024) says U.S.-only delivery and fulfilment within 2 business days; the homepage says orders ship within the United States and UK in approximately 5–7 business days (read 18 Sep 2026).
!Kits only — minimum spend for a single compound is $152. No returns accepted ('due to our rigorous quality control standards and the fragile nature of our products, we cannot accept returns'); cancellation only by email before shipment.
!Age-verification overlay and, on some listings, a 'please login to view products' prompt; prices were readable logged out on 19 Sep 2026. 'Pay with crypto — save 5%' offered.
Shanghai Nexa Pharma Co — About page (19 Sep 2026). No street address, no phone.
2026-09-198/10 — first assessment (rubric v2); not awarded: claims-consistent (shipping policy vs homepage), identity (no street address)
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.
Nexaph: the caveat
Sells in 10-vial kits only — the BPC-157 10mg kit is $152 (list $178), so the minimum spend is high and our single-vial price index cannot place it. The legal entity is printed as Shanghai Nexa Pharma Co with no street address anywhere on the site. Its shipping policy page says US-only and fulfilment within 2 business days while the homepage says US and UK shipping in 5–7 business days. Some listings show a 'please login to view' prompt though prices were readable logged out on 19 Sep 2026. Crypto payment earns a 5% discount; no returns accepted.

Where the evidence points
Purgo Labs 10/10
We earn nothing from Nexaph. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — with a live, independent review record.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. Nexaph is stronger on 2 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 Nexaph legit?
Nexaph scores 8/10 on our rubric, has an independently viewable rating of 3.9 (73 reviews), and names its lab (Janoshik Analytical). Caveat: Sells in 10-vial kits only — the BPC-157 10mg kit is $152 (list $178), so the minimum spend is high and our single-vial price index cannot place it. The legal entity is printed as Shanghai Nexa Pharma Co with no street address anywhere on the site. Its shipping policy page says US-only and fulfilment within 2 business days while the homepage says US and UK shipping in 5–7 business days. Some listings show a 'please login to view' prompt though prices were readable logged out on 19 Sep 2026. Crypto payment earns a 5% discount; no returns accepted.
Which is cheaper, Purgo Labs or Nexaph?
We do not yet have a like-for-like price pair for these two vendors; the Peptide Price Index has each vendor's dated readings.
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders; we earn nothing from Nexaph. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
