About BioSim Peptides
BioSim Peptides supplies research peptides to laboratories, universities and independent researchers. Every product we sell is intended strictly for in vitro and laboratory research. We do not sell products for human or veterinary use, and we do not give guidance on using them in people or animals.
Our catalog covers several areas of study, including neuropeptides, growth hormone secretagogues, mitochondrial and metabolic research compounds, tissue repair peptides and reproductive-axis research tools. We also carry research blends and laboratory supplies such as Hospira bacteriostatic water in 30 mL vials. Each product page lists the compound, the amount per vial and the key specifications researchers need to plan an experiment.
We keep our approach simple: accurate listings, independent testing of every lot, quick dispatch and direct support by email.
What We Do
Reproducible research depends on knowing what is in the vial. Our job is to supply well-characterized research materials and to make the supporting documentation easy to find, so researchers can spend less time checking a supplier and more time on their work.
We focus on a small number of commitments and keep them consistent across the catalog:
- 99%+ purity across our research peptides
- Every lot third-party tested, with identity confirmed by mass spectrometry
- Certificates of analysis published on our COA page
- Orders shipped within 2 business days
Testing and Certificates of Analysis
Every lot of every research peptide we sell is tested by an independent third-party laboratory. Testing confirms the identity of the compound by mass spectrometry and checks purity against our 99%+ standard.
We publish certificates of analysis on our COA page, so you can review the results for the material you are ordering at any time. Certificates are not included in the package with your order; the COA page is where they are kept and is always the most current source. Our guide on how to read a certificate of analysis explains each section of a certificate, and our Quality and Lab Testing page describes the process in more detail.
