Name: Peptide Therapy London — Doctor-Led Consultations
Creator: Dr. Ethan Hausman-Marquis

Question 1

What are peptides?

Accepted Answer

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, inflammatory signaling, and metabolic function. At The Catalyst Clinic, all discussions take place within a private medical consultation with a qualified clinician.

Question 2

Is peptide therapy legal in the UK?

Accepted Answer

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.

Question 3

What is the safest peptide clinic in London?

Accepted Answer

Safety in peptide therapy is determined by the clinical process surrounding it, not the compound alone. The safest peptide 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. At The Catalyst Clinic, mandatory bloodwork, pharmacy-grade compounds, and monthly clinical reviews are non-negotiable standards applied to every patient.

Question 4

What is the difference between peptide therapy and HGH?

Accepted Answer

HGH is a direct hormone replacement that introduces synthetic hormone into the body, bypassing the pituitary and suppressing natural GH production over time. Peptide secretagogues such as CJC-1295 and Ipamorelin signal the pituitary gland to produce its own growth hormone naturally, preserving the body's regulatory feedback mechanisms. The Catalyst Clinic does not offer HGH — only peptide-based approaches that work with your biology.

Question 5

How much does peptide therapy cost in London?

Accepted Answer

At The Catalyst Clinic, programs 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.

Question 6

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

Accepted Answer

The Catalyst Clinic is the only clinic in London where every program 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 before any consultation and pharmaceutical-grade compounds from GMP-certified, EMA-regulated pharmacies are non-negotiable standards at The Catalyst Clinic.

Question 7

Are the peptides at The Catalyst Clinic pharmaceutical grade?

Accepted Answer

Yes. Every compound discussed within a Catalyst Clinic program 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. The Catalyst Clinic does not source from unregulated vendors or grey-market suppliers.

Question 8

Is bloodwork required before a peptide consultation?

Accepted Answer

Yes — mandatory. Bloodwork establishes your baseline hormone levels, inflammatory markers, metabolic function, and organ health. Without this data it is not possible to design a safe, clinically appropriate program. This standard applies to every patient at The Catalyst Clinic regardless of age, health history, or stated goals.

Question 9

Can I access The Catalyst Clinic remotely?

Accepted Answer

Yes. The Catalyst Clinic offers remote consultations for patients across the UK, Europe, the UAE, Australia, Canada, and the United States. The clinical standard — mandatory diagnostics and ongoing monitoring — remains identical for all patients regardless of location.

Question 10

Does The Catalyst Clinic serve patients in Europe?

Accepted Answer

Yes. The Catalyst Clinic operates clinics in London (96 Kensington High Street) and Zürich (Bahnhofstrasse 10), and offers remote consultations for patients across the UK, Europe, UAE, Australia, Canada, and the United States. All programs follow the same mandatory diagnostics and clinical oversight standards regardless of location.
