About Life Link Research
Who We Are
Life Link Research is a US-based research peptide company founded on one premise: that researchers deserve the same quality documentation for their peptides that pharmaceutical manufacturers produce for drug substances. We synthesize peptides at our US-based facility, test every batch through a six-panel independent laboratory protocol, and publish every Certificate of Analysis publicly — batch number, test date, all six results — before a single vial ships.
We are not a rebranded overseas supplier. We are not a dropshipper. Our peptides are synthesized in the United States using Fmoc solid-phase peptide synthesis, purified by reverse-phase HPLC, and tested by Janoshik Analytical, the most-cited independent peptide testing laboratory in the research community.
Why We Built This
The research peptide industry grew rapidly with almost no quality infrastructure. For years, “testing” meant running an in-house HPLC on your own equipment and printing a number on a PDF with your own logo. There was no independence, no standardization, and no accountability.
The regulatory enforcement wave of 2025–2026 — which shut down Amino Asylum, Paradigm Peptides, Science.bio, and Peptide Sciences — was the inevitable result. Every one of those closures involved vendors who had cut corners on quality documentation, drifted into human-use marketing, or both.
We built Life Link Research to be the vendor we wished had existed — one that treats researchers as professionals, publishes real data, and operates as if an FDA inspector might walk in tomorrow. That’s not performative. It’s the only sustainable model for this industry going forward.
Our Standard
Every batch we ship is tested for six things by an independent lab:
- Identity (LCMS)
- Purity (RP-HPLC, ≥99%)
- Residual solvents (GC, ICH Q3C)
- Heavy metals (ICP-MS, USP <232>)
- Bacterial endotoxin (LAL, USP <85>)
- Sterility (USP <71>)
Most vendors test two of those six. The most rigorous test three or four. We test all six, every batch, and the results are on the COA library for every customer to review before and after ordering.
What We Don’t Do
- We don’t market our products for human use. Every product page carries a clear “for research use only” disclaimer because that is what these products are.
- We don’t inflate purity numbers. We don’t have in-house COAs. Our testing is done by a lab that doesn’t sell peptides and has no financial incentive to make our numbers look better than they are.
- We don’t hide failed batches. If a batch fails any test, it is quarantined. It does not ship. Period.
Our Lab Location
We synthesize and test from our US-based facility. [City, State]. We are not a virtual storefront — we have a physical address, a real lab, and a team that answers support emails.
Our Testing Partner
Our COAs are issued by Janoshik Analytical, an independent analytical laboratory based in the Czech Republic that is widely recognized as the most credible third-party testing partner in the research peptide industry. Janoshik tests for vendors — they don’t sell peptides — which means their results are not subject to the conflict of interest that exists when a vendor issues its own COA.

For Researchers
Our products are sold strictly for laboratory research use. They are not intended for human or veterinary consumption. The statements regarding our peptides have not been evaluated by the U.S. Food and Drug Administration. Our products are not intended to diagnose, treat, cure, or prevent any disease.
We sell to qualified researchers who understand what they are purchasing and operate in compliance with the laws and regulations governing research chemical handling in their jurisdiction.
