Work with me
Consultations, programmes and testing, with me reading your results.
You complete your Case File first and I prepare your Health Status Report from it, so we start with your picture. Clear direction, a specific testing pathway, and an honest conversation about which programme, if any, is the right fit. The £145 is credited against the TDG programme, the Resilient Gut System or the Resilient Stress System if you go ahead within 60 days (not against single tests or monthly coaching). Not sure yet? The free 20-minute call comes first.

The Metabolic Natures Programme
For “every diet works for someone else”. A starting reading on two axes from a questionnaire, a food guide, menu plan and recipes for your plate, and a follow-up where the plan is checked against how you actually cook and eat. A starting point, not a test result.
Results & Plan
A full read of your test results with a consultation, a plan and a follow-up: a blood panel ordered through me, or GI-MAP, DUTCH Plus or OAT results.
Personal training
Personal training at home in the Edinburgh area or by Zoom, a training programme written for you, or online training coaching.
A written answer to one question, within 3 working days. Fill in a short form, attach anything useful (wearable screenshots, old results, what you take now), and I reply with what I think is going on, one or two things to try, whether a test would answer it, and anything that means your GP instead. One follow-up question within 14 days is included, and the £45 comes off a check-in, consultation, test or programme booked within 60 days. Prefer to talk? A check-in, £75. Everything for existing clients is on one page.
Individual specialist tests and paired investigations that answer specific clinical questions — available separately from the TDG five-test programme.

The TDG Clinical Manual
The reasoning behind Test, Don’t Guess: what each test measures and what it can’t tell you, how the body’s systems connect, and how a protocol is built from your own results. 13 modules, about 170 pages. Module 10 uses the older version of Metabolic Natures: read it as a starting point, not a tested rule. Not a dosing guide: doses are set after testing.
TDG Clinical Manual: Module 01
The first module, free to read: why generic advice fails, and the reasoning the other twelve modules are built on.
Metabolic Natures, Volume 1
Stephen’s metabolic framework and how to find your starting point. In paperback and on Kindle.
