Overview

Peptide Sciences is a US-based research chemical supplier operating since approximately 2012, positioning itself as a mid-to-premium vendor selling peptides labeled strictly “for laboratory research only.” The company has built significant name recognition in the grey-market peptide space — arguably the most well-known US vendor — though that visibility has also attracted confusion with similarly-named competitors.

Testing & Quality

Score: 65/100

Peptide Sciences’ strongest asset is independent verification through Finnrick Analytics, which tested 12 BPC-157 samples between December 2024 and November 2025 and awarded a confident Finnrick A rating (“Great”) — average score above 7.0, no score below 6.0. This places them alongside Peptide Partners and Eternal Peptides in the top tier for BPC-157 specifically.

However, Peptide Sciences relies primarily on internal COAs rather than publicly displaying third-party lab reports. The company does not routinely publish batch-specific endotoxin or sterility testing data. Their site states products “have not been sterilized or tested by PeptideSciences.com for safety and efficacy.”

Transparency

Score: 50/100

Products advertise 99%+ purity but detailed supporting documentation is inconsistent. COA availability appears to vary — some customers report receiving COAs on request, others report difficulty obtaining them. No publicly accessible lab report archive comparable to vendors like Verified Peptides or Peptide Partners.

Pricing

Score: 55/100

Mid-to-premium pricing. BPC-157 and blends carry significant markups relative to competitors. Bulk “Bundle & Save” program offers 20-vial packages. Pricing is clearly listed on-site, which is a positive.

Reputation

Score: 55/100

Reviews are genuinely polarized:

  • Trustpilot: Mixed reviews, with long-term customers praising quality and newer buyers reporting issues
  • Sitejabber: 2.4/5 from 14 reviews
  • WorthEPenny: 4.0/5 from 141 reviews
  • Reddit: Generally positive historical reputation, though increasingly scrutinized

No refund/return policy — replacements only for wrong product shipped.

The Bottom Line

Peptide Sciences benefits from one of the strongest independent testing records in the grey market (Finnrick A for BPC-157), a decade-plus operating history, and fast US shipping. But the reliance on internal-only COAs for most products, zero refund policy, inconsistent customer service, and premium pricing without commensurate transparency prevent a higher grade.
