What are research peptides and how are they produced?
Research peptides are short chains of amino acids supplied for controlled in-vitro laboratory work. They are typically made by solid-phase peptide synthesis (SPPS), then purified and lyophilised to a dry powder. Apex Pharma supplies identified research compounds to laboratories from the UK. Format (vial or pen) and available sizes are listed on each product page.
Do your peptides contain mannitol or bulking agents?
No. Our vials contain lyophilised peptide only. No mannitol, excipients or bulking agents are added.
Why does my vial look almost empty or have very little powder?
Lyophilised peptides are low-density. A few milligrams can look like a thin film or faint residue. Appearance alone is not a fill check. Use the label quantity and, where listed, the matching external report.
