Peptide bioregulators
Peptide bioregulators are very short sequences - often two to four residues - studied for their interaction with gene expression and tissue-specific regulation. The range includes epitalon (Ala-Glu-Asp-Gly), thymalin, cortagen, cardiogen, crystagen and pinealon.
Their brevity makes analytical confirmation important: short peptides are easy to synthesise inconsistently and difficult to distinguish by eye. Every bioregulator product has undergone independent reverse-phase HPLC and mass-spectrometry testing.

Peptide Bioregulators, answered
- Why does purity testing matter more for very short peptides?
- Short sequences have low molecular weights and closely related synthesis by-products, so deletion sequences and salt content can be a large proportion of the mass without being visible. Independent HPLC and LC-MS testing provides objective product-level evidence of purity and identity.
- Has every peptide bioregulator product been independently tested?
- Yes. Every product has undergone independent HPLC and LC-MS testing, and certificates of analysis are available to view on the relevant product pages.
- How quickly are orders dispatched?
- Orders that clear payment before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery to the United Kingdom and the European Economic Area countries we serve.
- Can these compounds be used on humans or animals?
- No. Everything in this range is an unlicensed reference standard supplied for in-vitro laboratory research by qualified professionals only. Nothing we sell is a medicine, supplement or cosmetic.
