Comparison checklist

How to read this checklist: ✓ Yes · ◐ Partial · — Not confirmed

Prescriber or medical oversight shownThe official trail names Dr Chia Tan and describes doctor-prescribed peptide treatment. His published GMC number now has a matching direct GMC record, while the clinic's CQC claim remains unconfirmed.
Consultation describedThe peptide page describes medical assessment before prescribing, but the full appointment workflow should still be confirmed directly.
Testing or bloodwork describedThe peptide page describes laboratory testing as part of the pathway, but test scope and timing should be confirmed directly.
Follow-up monitoring describedThe peptide page describes regular follow-up and monitoring, but the exact review schedule is not independently verified.
Pharmacy or dispensing route disclosedA dispensing route is hinted at, but not fully named.
Legal entity verifiedNo clear matching company record is visible.
Direct regulator record verifiedThe direct GMC record for Chia Tsyh Tan matches GMC number 6071104 published on his Harley Street MD profile.

Identity and regulatory checks

The reviewed public trail is materially stronger than a bare treatment page. Harley Street MD’s homepage embeds MedicalClinic schema, the site publicly names Dr Chia Tan as founder and medical director, the peptide page describes a doctor-led prescribing pathway with laboratory testing and follow-up, and the contact page shows a usable Wimpole Street address plus direct phone and email contact details.

Dr Chia Tan’s official profile publishes GMC number 6071104 and links to the regulator. The direct GMC record names Chia Tsyh Tan, shows the same reference number, and showed registration with a licence to practise when checked on 2 August 2026. The clinic's CQC claim remains unconfirmed because no direct matching CQC record was safely attached; the named GPhC dispensing trail and Companies House match also remain open.

This record now includes a direct GMC clinician match. A direct CQC clinic match, dispensing-pharmacy trail, and legal-entity match still need independent verification.

Questions to ask before booking

Before booking, these are the main public-trail questions still worth clarifying:

  • Which legal entity operates Harley Street MD?
  • Which clinic or provider record, if any, is the relevant CQC match for this service?
  • Which pharmacy dispenses the prescribed peptides, and is it GPhC-registered?
  • Which peptide compounds are prescribed on-label versus off-label in the clinic’s pathway?
