Trusted Lab Tested Peptides – 99%+ Pure – HYB Peptides

Lab Tested Peptides – Full Transparency & Third-Party Verification at HYB Peptides™

At HYB Peptides, we understand that serious researchers demand serious proof. That’s why every single peptide we sell is lab tested by Janoshik Analytical — the gold-standard independent laboratory trusted by the global research peptide community.

We don’t just claim high purity — we prove it. Every batch of lab tested peptides comes with a complete, publicly available Certificate of Analysis (COA) performed by Janoshik Analytical in ISO-17025-accredited facilities. These reports are dated, signed, and include the exact batch number printed on your vial label, so you always know the document matches the product in your hands.

What exactly do our lab tested peptides reports include?

• High-Performance Liquid Chromatography (HPLC) showing actual purity — typically ≥98%, with most batches testing 99%+
• Mass Spectrometry (MS) confirming correct molecular structure and molecular weight
• Amino acid sequence verification when applicable
• Residual solvent analysis
• Heavy metal screening
• Endotoxin testing on request

Janoshik Analytical uses fully calibrated equipment and follows strict GLP (Good Laboratory Practice) standards. The reports are impossible for us to alter, giving you 100% confidence that the results are genuine and unbiased.

Why we only sell lab tested peptides (and never in-house tested ones)

Many suppliers cut corners by performing “in-house” testing or skipping third-party verification entirely. We refuse to do that. Every new batch of lab tested peptides is sent to Janoshik before a single vial is bottled. If purity falls below our strict ≥98% threshold, the entire batch is rejected and destroyed. No exceptions.

This commitment means you receive only the highest-quality research compounds available anywhere in the world.

How to read and verify your Janoshik report

1. Find the batch number printed on your vial label (e.g., BPC-240312)
2. Scroll through the table below or visit the individual product page
3. Click the matching Janoshik PDF
4. Verify the batch number, purity percentage, and test date match your order

It’s that simple. Full transparency, every time.

lab tested peptides
Every research peptide sold by HYB Peptides is independently verified by Janoshik Analytical with full third-party certificates of analysis. All batches undergo HPLC purity testing and mass spectrometry, routinely achieving ≥98% purity, with results published for complete transparency. Researchers receive the exact Janoshik report matching their vial’s batch number. We never use in-house testing or altered documents — only genuine, dated COAs from Janoshik. Popular compounds including BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide, and others are all sent to Janoshik before release. If a batch does not meet our strict purity standard it is rejected and destroyed. Reports include HPLC chromatograms, mass spec data, residual solvent screening, and heavy-metal results when applicable. All products are intended strictly for licensed laboratory research and in-vitro studies only, never for human or animal consumption. HYB Peptides ships worldwide with discreet packaging and tracked delivery to the United States, Canada, United Kingdom, European Union, Australia, and dozens of other countries. Full documentation is available on every product page and in our centralized report database.
