Most research-peptide vendors publish a single “representative” certificate of analysis and reuse it across batches. Bastion publishes the independent Janoshik result for every production batch — and this report aggregates them in one place, with a live verification link for each so you can confirm every number against Janoshik’s own database rather than taking ours on faith.
Research use only. All figures below are independent third-party analytical results for laboratory research materials. Nothing here is medical guidance, and these compounds are not for human or veterinary consumption.
Headline findings (current verified batches)
- Every quantified single-peptide batch tested ≥98.4% HPLC purity.
- 7 of 8 single peptides tested ≥99%. Mean purity across them: 99.34% (range 98.43%–99.66%).
- Every result is independently verifiable on Janoshik Analytical’s own domain — not a vendor-hosted PDF.
- Multi-peptide blends (GLOW, KLOW) were composition-confirmed by mass, and NAD+ was independently quantified.
- SKUs without a current independent result are labeled “Lab Analysis Pending” rather than carrying a reused or representative COA forward.

Live per-batch certificates and verify links are maintained on the Lab Results archive; this report summarizes the distribution.
How these numbers were produced
Every batch is submitted to Janoshik Analytical — an independent third-party laboratory in Czechia widely used across the research-peptide community — for:
- HPLC to quantify purity (percent of target compound vs. impurities), and
- LC-MS to confirm identity and mass accuracy.
Results are issued against the specific production batch (our Match-Batch process), not a representative sample, and each is published with a verification code that resolves to a record on Janoshik’s own servers — which is why a fabricated or edited certificate cannot pass the check.
Why publish the whole distribution?
A single 99% COA tells a buyer almost nothing about the batch in their hand. Publishing the full set — including the lower results and the SKUs still pending — is the honest version of “lab-tested.” It lets a researcher see the real spread, confirm each figure independently, and judge consistency across compounds rather than trusting one cherry-picked number.
How to verify any of these yourself (60 seconds)
- Open the Janoshik record linked in the table (or go to janoshik.com/verify and enter the task number).
- Confirm the compound name matches the row above.
- Confirm the HPLC purity and the identity (mass-spec) result.
- Confirm the date and batch reference. If anything doesn’t resolve on Janoshik’s own domain, treat the certificate as invalid.

Transparency on what isn’t here yet
At the time of writing, 15 catalog SKUs are marked Lab Analysis Pending on the Lab Results page — current inventory tested, next batch not yet independently re-verified. We flag these explicitly instead of copying an old certificate forward. This report will be updated as new batches clear Janoshik.
