The Hormonal Orchestra
Hormones are the master messengers of the body — chemical signals produced by endocrine glands that travel through the bloodstream to regulate virtually every physiological process: metabolism, growth, reproduction, immune function, mood, cognition, sleep, and the rate of biological ageing itself. They do not play the instruments of your biology — they tell every instrument what to play, when, and at what volume.
The endocrine system is not a collection of independent glands each doing their own thing. It is a deeply interconnected network in which every hormone influences the production and activity of every other hormone. Testosterone affects insulin sensitivity. Cortisol suppresses thyroid function. Oestrogen influences serotonin and dopamine. Growth hormone affects IGF-1. Melatonin modulates cortisol. This web of interactions means that optimising one hormone in isolation, without understanding the whole system, is like turning up the volume on one instrument and wondering why the whole song sounds wrong.
This is why SEVYN's approach to hormonal health is comprehensive — we assess the full hormonal picture and understand the interactions before making any intervention.

Protocols
- ◆Resistance training 3–4x per week (most powerful natural testosterone stimulus)
- ◆Sleep optimisation (testosterone is primarily produced during deep sleep)
- ◆Stress management (cortisol directly suppresses testosterone production)
- ◆Zinc 15–30mg daily (essential cofactor for testosterone synthesis)
- ◆Vitamin D3 to optimal levels (strongly correlated with testosterone)
- ◆Reduce alcohol consumption (directly suppresses testosterone and disrupts oestrogen metabolism)
- ◆Comprehensive hormonal panel (full thyroid, sex hormones, DHEA-S, cortisol, IGF-1)
- ◆Ashwagandha KSM-66 300mg 2x daily (clinically validated testosterone increase in men)
- ◆Tongkat Ali 400mg daily (LH stimulation, testosterone support)
- ◆DHEA supplementation guided by measured DHEA-S levels
- ◆Boron 6–10mg daily (reduces SHBG, increases free testosterone)
- ◆Magnesium glycinate 400mg (reduces SHBG, improves free testosterone)
- ◆Bioidentical HRT/TRT under clinical supervision with regular monitoring
- ◆Ipamorelin/CJC-1295 peptide for growth hormone support
- ◆Comprehensive thyroid optimisation (T3 therapy if conversion is impaired)
- ◆Oestrogen metabolite testing (DUTCH test) for comprehensive hormonal picture
- ◆Melatonin timing and dosing calibration
- ◆Quarterly hormonal monitoring panels
Key Biomarkers
- ●Total testosterone (men: target 600–900 ng/dL; women: target 20–60 ng/dL)
- ●Free testosterone (more clinically relevant than total)
- ●Oestradiol (E2) — men and women
- ●DHEA-S (target: upper third of reference range)
- ●TSH, Free T3, Free T4, Reverse T3
- ●IGF-1 (proxy for growth hormone activity)
- ●Cortisol (diurnal pattern via saliva)
- ●SHBG (sex hormone binding globulin)
