Fighting misinformation with analytical data

Most people buying research peptides today have no reliable way to verify what they received. Vendors provide Certificates of Analysis, but these are almost universally self-issued — produced by the same party selling the product, from a batch they selected themselves.

This creates obvious information asymmetry. A COA supplied by a vendor cannot, by definition, be independent. It tells you what the vendor wants you to believe about their product. The result is a market driven by influencer reputation, forum word-of-mouth, & recycled documents — not by verifiable analytical data.

Misinformation in this space is not just commercial. Wrong-compound results — samples that are not what they claim to be — circulate without any public record. Users attribute effects (or the absence of them) to the wrong substance. That misattribution compounds over time and becomes received wisdom on forums & social media.

Drug checking services like saferparty.ch do excellent harm-reduction work — but they are built for recreational substances, not research peptides. Their methods (colorimetric tests, thin-layer chromatography) are well-suited to detecting the presence of small molecules in street drugs, but they cannot identify a peptide by mass or quantify synthesis impurities at the level that matters here.

Research peptides require ESI-TOF mass spectrometry for identity confirmation & RP-HPLC-MS for quantitative purity assessment. No consumer-facing service offers this for the peptide market. Certipep was built specifically to fill that gap.

Certipep is a consumer-facing analytical testing service. You purchase a verification, we mail you a collection envelope, you send us your sample anonymously, & we run it through ESI-TOF mass spectrometry at a Zurich-based analytical lab. Every result is reviewed by a PhD-level analytical chemist. Methods follow ICH Q2(R1) validation guidelines.

We report two things:

Analytical testing has real limits & we want to be honest about them.

• Biological activity. A peptide can be analytically correct (right mass, high purity) & still be biologically inactive due to incorrect folding, oxidation, or degradation. Mass spectrometry cannot confirm efficacy.
• Sterility testing. We do not test for sterility. Endotoxin testing & a heavy metals panel are available as add-ons, but full sterility assessment requires a separate certified test.
• Sequence confirmation. ESI-TOF-MS confirms molecular weight. It does not sequence the peptide amino acid by amino acid. For most common peptides the mass match is sufficient; for novel or modified peptides it may not be.
• Regulatory submissions. We are not a GMP or ISO 17025 accredited facility. Results are not intended for regulatory filings.

The critical design decision behind Certipep is who submits the sample.

We only accept submissions from end users: the people who purchased the peptide & received it. We do not accept submissions from vendors, suppliers, or distributors. A vendor could trivially select their best batch, run one clean test, & use that report on everything they sell. That defeats the purpose entirely.

When a customer submits a sample they personally received, the report reflects what is actually being sold & shipped, not a curated showcase batch.

By default, every submission is made public. Customers can opt out at submission time, but open publication is the default. That is the point.

Every result is published to a public ledger. Over time, this builds something more valuable than any individual test: a community database of real-world peptide quality, by supplier & batch.

Suppliers with consistently clean results become visible. Suppliers with repeated failures or wrong-compound results become visible too. No rankings, no ratings. Just raw analytical data, openly published.

The goal is not to police the market. It is to make information available that currently is not.

Certipep was founded by a Zurich-based organic chemistry PhD deeply involved in strength training, ultra endurance & triathlon. The access to analytical instrumentation at Zurich research labs, the understanding of what the data actually means, & first-hand experience with the research peptide market are what make this credible — not a marketing arrangement.

That background is also why the scope of what we claim is deliberately narrow. A chemist knows exactly where the limits of a technique are.
