Peptides are short chains of amino acids that act as biological messengers within the body. They occur naturally — insulin and GLP-1 are peptides — and scientific research is exploring how synthetic versions may interact with cellular repair pathways, hormone regulation, tissue regeneration, and metabolic function. At The Catalyst Clinic, all discussions take place within a private medical consultation.

Is peptide therapy legal in the UK?

Yes. Peptide compounds are not licensed medicines under the Human Medicines Regulations 2012, which means GMC-registered physicians can legally discuss and advise on them within a regulated private medical consultation. The Catalyst Clinic operates in full compliance with MHRA, ASA, and CQC guidance.

How much does peptide therapy cost in London?

At The Catalyst Clinic, programmes start from £600 per month, which includes mandatory pre-consultation bloodwork, a personally designed protocol by Dr. Ethan Hausman-Marquis, pharmaceutical-grade compounds from GMP-certified pharmacies, and ongoing monthly reviews. An initial consultation fee applies from £150.

How is The Catalyst Clinic different from other peptide clinics in London?

The Catalyst Clinic is the only clinic in London where every programme is designed and overseen by a physician with a PhD in Cell and Genomic Biology (Karolinska Institute) and nearly 20 years of peptide-specific research experience. Mandatory diagnostics and pharmaceutical-grade compounds from GMP-certified, EMA-regulated pharmacies are non-negotiable standards.

Are the peptides at The Catalyst Clinic pharmaceutical grade?

Yes. Every compound is sourced exclusively from GMP-certified, EMA-regulated, and FDA-registered compounding pharmacies. Each compound is accompanied by a certificate of analysis confirming identity, purity, and potency.

What is the safest peptide clinic in London?

Safety in peptide therapy is determined by the clinical process, not the compound alone. The safest clinic is one supervised by a GMC-registered physician, based on comprehensive pre-consultation bloodwork, using pharmaceutical-grade compounds from GMP-certified, EMA-regulated pharmacies, with ongoing monitoring throughout.
