How BioSignal Works
Your BioSignal programme is carefully designed to give you complete certainty about your health and objective proof it is improving in as little as 90 days.
Week 1: The Precision Baseline
No clinic visits. A certified phlebotomist comes directly to your home or office. We run an extensive blood panel measuring the markers your standard GP ignores.
Week 3: The First Surge
Your dedicated coach deploys your custom routine. Expect a noticeable lift in your morning energy, deep sleep quality, and daily cognitive focus.
Week 6: Habit Lockdown & System Shift
Your customized protocols are automatic. Early tracked biomarkers have shifted, eliminating afternoon crashes and accelerating physical recovery. You begin to rediscover the "real you".
Day 90 Onwards: Retest & Optimise
We draw your blood again. You see the exact improvement in your hormones, inflammation, and key health markers. This becomes the baseline for "optimisation" and is where the real fun begins...
Dedicated 1:1 Coaches
Full Medical Team
At-Home Blood Draw
Re-testing Included
The Biosignal Guarantee
If your targeted blood markers haven't measurably improved by Day 90, we will coach you for FREE until they do.
You either get your energy, focus, and biology optimised, or you don't pay another penny.

Frequently Asked Questions
You'll find out a bit more about us below, but the best way to find out if we're a good fit is to book a no pressure, no obligation call with one of our specialist team.
Who are BioSigal and GC Biosciences?
GC Biosciences is a UK-based clinical health optimisation company operating from Harley Street, London. We are a registered UK company (Companies House No. 08346259). Our founders, Rob Corney and Calum Gore, are named consultants with verifiable professional backgrounds.
We specialise exclusively in blood chemistry, metabolic health, longevity, and healthspan using lifestyle interventions such as nutrition counseling, exercise prescriptions, supplement and medication recommendations. We combine clinical-grade diagnostics with personalised coaching to help clients understand and actively improve their health.
Are you a regulated healthcare company?
GC Biosciences is a registered UK company (No. 08346259), verifiable at companieshouse.gov.uk, we are also registered with the Care Quality Commission (Pending).
We operate from Harley Street, one of the most regulated private medical addresses in the world. All blood samples are processed by UKAS-accredited laboratories, the same accreditation required by NHS pathology labs.
Our practitioners have verifiable qualifications and professional backgrounds that can be researched independently
How is this different from just getting a private blood test?
A private blood test gives you data. GC Biosciences gives you a plan, a person, and proof.
After your results are interpreted by our clinical team, you receive a blood-matched nutrition strategy, a personalised supplement protocol, and a dedicated nutritionist who works with you for 90 days, weekly check-ins, WhatsApp support, and full accountability.
At the end of the programme we retest everything and show you in numbers what changed. Data without action is just noise.
How is this different from Medichecks, Thriva, or Randox?
Those companies send you a report and the relationship ends.
There is no interpretation specific to your situation, no nutrition plan, no coaching, and no accountability. GC Biosciences tells you what every result means for your health, builds a personalised plan around your biology, and coaches you through it with a dedicated nutritionist.
We also use a full venous draw rather than a finger-prick kit, which produces significantly more reliable data.
What does the 90-day programme include?
The programme includes: comprehensive blood testing with two at-home nurse visits, PhD-level clinical interpretation against optimal ranges, your personal 360 Health Blueprint, a blood-matched nutrition strategy, a personalised supplement and medication protocol where appropriate, a dedicated nutritionist with weekly check-ins and WhatsApp support for 90 days, and a full retest with before-and-after biomarker comparison at the end.
Investment and availability are discussed on your free consultation call.
What is the Biomarker Improvement Guarantee?
If your key biomarkers do not improve after completing the programme and following the protocol, we keep working with you at no additional cost until they do.
We measure our success by your results, not your enrollment.
