Powerful research, backed by science.
Our commitment is simple: provide researchers with the highest-purity peptides and compounds, backed by transparent testing and quality standards we never compromise.
47 research compounds · 44 certificates, published openly · based in Florida
Researchers deserve materials they can trust completely.
KratoLabs was founded on a simple conviction. Too often across the industry, purity is assumed rather than demonstrated, and sourcing is left poorly documented. We built our company around the opposite principle — verifiable quality and full transparency at every step.
Our compounds are tested by independent laboratories, and the Certificates of Analysis are published openly. We believe that dependable, well-characterized inputs are the foundation of reproducible science.
Demonstrated, not assumed. Here’s one.
This is a real report from our archive, unedited. Every ILS Laboratories certificate for a KratoLabs lot is laid out the same way — these are the parts worth checking.

From synthesis to your bench.
How a compound gets to you — and the parts of it you can check for yourself.
- 01 / 05
Synthesis
Compounds are synthesized using tightly controlled processes built for molecular accuracy, and held to research-grade purity specifications before they move on to outside testing.
- 02 / 05
Independent testing
Batches go to independent third-party laboratories. Depending on the lab, the certificates in our archive report:
- HPLC purity
- Area-normalised at 214 nm
- Identity
- Retention-time match to a reference standard
- Net peptide content
- Measured mg in the vial
- Fentanyl screen
- Immunoassay, 50 ng/mL cutoff
HPLC purity · every KratoLabs lot so far - GLP-3 RT RT000198.52%
- GLP-2 TZ TIRZ000198.45%
- Tesamorelin TESA000198.67%
- BPC-157 BPC000199.87%
- SS-31 SS31000199.44%
- Glutathione GLUTA000196.96%
All tested by ILS Laboratories. The scale starts at 90% so the differences are visible.
