Blank Peptides vs Peptide Plugs: 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

- 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); Peptide Plugs' domain was registered Dec 2025 (9 months ago).
- Blank Peptides says it ships to the US, and internationally; Peptide Plugs says it ships to the US.
