How we verify every batch

Every compound we sell is tested before it ships — and you can see the results for the exact vial you receive.

Standard: ≥99% by UPLC Testing: 3rd-party · U.S. Last updated Jun 2026
In short

Every tuned batch is tested by an independent U.S. laboratory for purity (UPLC), identity (mass spectrometry), and endotoxin — and ships with a batch-specific Certificate of Analysis tied to its lot number. Our standard is ≥99% purity. If a batch doesn't meet it, it doesn't ship.

01 — Why this page exists

For research peptides, quality is the whole game

With research compounds, the biggest real-world risk usually isn't the molecule — it's the material.

Two vials can carry the same name and be very different inside: different purity, the wrong compound entirely, or contamination that never shows up on a label. Published research is run on controlled, high-grade material; a lot of what circulates in the wider market is not. That gap is exactly what verification closes — so we test every batch and show you the proof.

02 — How we test

Four checks on every batch

Purity — UPLC

High-performance liquid chromatography separates the sample so any impurities show up as distinct peaks. The result is a precise purity percentage.

Standard: ≥ 99.0%

Identity — mass spectrometry

Mass spec measures the compound's molecular weight to confirm it's actually the peptide on the label — not a look-alike or a mislabelled substitute.

Result: identity confirmed

Endotoxin screening

Bacterial endotoxins are a common contamination risk in lower-grade material. We screen each batch and hold it to a strict limit.

Limit: < 0.05 EU/mL

Appearance & fill

Each vial is checked for correct appearance, the lyophilized (freeze-dried) state, and accurate fill before it's released.

Visual + weight check
The standard is a gate, not a target. ≥99% purity is the minimum to ship. A batch that falls short is rejected — it doesn't get sold at a discount or relabelled.
03 — Independent testing

Third-party, in the U.S.

Testing is done by an independent laboratory in the United States — not in-house. Independent results carry more weight precisely because they're not ours to influence, and U.S. testing means a consistent, accountable standard you can trace.

04 — Reading a Certificate of Analysis

What's on a CoA — and what each line means

A Certificate of Analysis is the lab's report for a specific lot. Here's a sample, annotated so you know what you're looking at:

  • Compound & lot — the exact product and the specific batch. The lot ties the certificate to the vial in your hand.
  • Identity — confirms (by mass) it's the right peptide.
  • Purity — the headline number; the share of the sample that is the target compound.
  • Endotoxin — contamination screen; lower is better, with a hard pass/fail limit.
05 — Where our research comes from

How we write about compounds

Our compound pages summarise published research, and we hold the writing to the same standard as the lab work:

  • Every claim is traceable. Statements about how a compound works trace to named primary sources — peer-reviewed papers and clinical-trial records — listed on each page.
  • We don't dress up community claims as science. Where the only basis for a figure is anecdote or community protocol, we say so plainly rather than implying a study exists.
  • We don't give dosing or medical advice. Research dose ranges are presented as what the literature reports, never as instructions. Tools like our reconstitution syringe are measurement aids, not recommendations.
  • We date our pages. Each page shows when it was last reviewed so you can judge how current it is.
06 — Limitations & honesty

What testing does and doesn't tell you

A CoA verifies what's in the vial — purity, identity, contamination. It does not establish that a compound is safe or effective for any use, and for most research peptides there is limited or no human safety data. These are research compounds, sold for laboratory research only — not drugs, and not for human consumption.

Reporting an error

If you spot something on a CoA or a compound page that looks wrong, tell us — accuracy matters more than being right. Contact us with the lot number or page and we'll review it.
