Founded by a scientist,
providing peptides you can trust.
Johnathon Anderson, PhD
Founder
Peptide Systems was founded to solve a serious problem in the research community: the lack of high-integrity, verifiably tested peptides suitable for advanced mechanistic and translational work.
Every batch we release is tested in independent, ISO 17025:2017-accredited, U.S. laboratories, never assumed, never internally self-declared. Our Certificates of Analysis include verification of:
-
Purity: ≥ 99% (HPLC-confirmed)
-
Sterility: Verified sterile-filtered
-
Endotoxins (LPS): Not detected
-
Trifluoroacetic Acid (TFA): Not detected (LC-MS)
-
Molecular Identity: Confirmed (LC-MS)
-
Content Quantity: Confirmed (HPLC)
We exist so researchers have a reliable, transparent, GS1-standardized source they can trust, free from gray-market relabeling and unverifiable claims.
Founder
Dr. Johnathon Anderson is a research scientist and Associate Professor at the UC Davis School of Medicine, specializing in regenerative medicine, stem cell therapies, and translational drug development. His experience spans the full arc from early-stage discovery through execution of multi-site clinical trials.
He holds BS and PhD degrees from the University of California, Davis, and has been awarded competitive research fellowships including the NSF GRFP, NIH T32, and NIH KL2. His peer-reviewed publications have been cited over 11,000 times, and he is co-inventor on patents in advanced stem cell and exosome-based therapeutic technologies.
He has conducted research training at the National Institutes of Health, Karolinska Institute (Stockholm), and Oxford University (UK), and outside the lab, he is a loving father and a Brazilian jiu-jitsu blue belt.
