Blank Peptides vs NextGenPeps: prices, COAs and track record compared
Side by side from public evidence and live prices, checked Oct 15, 2026. Neither vendor paid to be here, and we haven't lab-tested either, so this compares openness and price, not purity.
The short answer
- NextGenPeps scores higher on our six public-information checks: 57/100 against 55/100, ahead on domain age, business identity and published policies (Blank Peptides leads on buyer-protected payment). Unfinished checks score 0 (NextGenPeps: 5 of 6 checks completed).
- We can't compare prices: we have none for Blank Peptides, because its shop has no public product feed we can read.
- Both publish only generic or sample COAs, not batch-specific ones.
- Blank Peptides' domain was registered Mar 2026 (7 months ago); NextGenPeps' domain was registered Apr 2025 (17 months ago).
- Both say they ship to the US, and internationally.
- We haven't lab-tested either vendor, so none of this measures purity.
