Blank Peptides vs PS Peptides: 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

• Blank Peptides scores higher on our six public-information checks: 55/100 against 22/100, ahead on naming an independent lab, business identity and buyer-protected payment. Unfinished checks score 0 (PS Peptides: 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); PS Peptides' domain was registered Nov 2025 (11 months ago).
• Blank Peptides says it ships to the US, and internationally; PS Peptides says it ships to the US, Canada, the UK, the EU and Australia, and internationally.
• We haven't lab-tested either vendor, so none of this measures purity.

Before you order from either

• Pay by card or PayPal where you can: both can be disputed if an order goes wrong.
