Peptides FAQ

Peptides are small chains of amino acids that serve as signaling molecules in the body. They regulate various biological processes, such as muscle repair, fat metabolism, and skin rejuvenation.

• Licensed Peptides: Some peptides, such as Semaglutide (Wegovy®), are licensed medicines in the UK and regulated by the MHRA. These products require a prescription.
• Research Peptides: Most peptides (e.g., BPC-157, GHK-Cu) are unlicensed and are available only for laboratory research purposes.

Semaglutide has been shown to produce significant weight loss in clinical trials, with participants achieving up to 15–16% weight loss over 1–2 years. It is licensed for obesity management in the UK.

Retatrutide is an experimental peptide currently in clinical trials, showing even greater weight loss potential (up to 24%).

In laboratory research, peptides are used to study a wide range of biological processes:

• Muscle repair and recovery: BPC-157, Ipamorelin
• Fat metabolism: Semaglutide, Tesamorelin
• Skin regeneration: GHK-Cu

• Look for transparency, including Certificates of Analysis (COAs).
• Choose a supplier that complies with MHRA guidelines.
• Verify customer reviews and third-party lab testing.

No. Most peptides sold for research purposes are not approved for human consumption in the UK.
