The Oestrogen Effect

Product Description

Your cycle is not working against you. It is the most sophisticated performance periodisation system available.

The Oestrogen Effect is the definitive performance guide to oestrogen — the hormone that shapes the menstrual cycle, the connective tissue, the brain, the cardiovascular system, and the body composition that all female performance depends on. This is not a general women’s health guide. It is a performance guide that uses hormonal biology as a competitive advantage.

Who Is This For

Women of any age who want to understand and leverage their hormonal biology for performance — from cycle-periodising athletic training to navigating perimenopause with evidence-based tools.

========================================== HPS G4 — The Thyroid Performance Protocol PRODUCT TITLE: The Thyroid Performance Protocol PRICE: $47 CATEGORY: Performance SHORT DESCRIPTION: The complete evidence-based guide to thyroid hormones — the overlooked metabolic regulator controlling energy, body composition, cognition, and every other hormone in the system. ========================================== LONG DESCRIPTION:

The thyroid is not just a metabolic regulator. It is the conductor of the hormonal orchestra. When it’s off, everything plays out of tune.

The Thyroid Performance Protocol is the definitive guide to understanding and optimising thyroid function for performance. Thyroid hormones set the metabolic rate of virtually every cell in the body. They control energy, cognition, mood, muscle function, body composition, and the sensitivity of cells to cortisol, insulin, testosterone, and oestrogen. When thyroid function is suboptimal — even subclinically — every system slows.

✓ Complete HPT axis physiology — TRH, TSH, T4, T3, and the conversion cascade ✓ Reverse T3: the thyroid’s emergency brake — what drives rT3 and how to calculate the T3:rT3 ratio ✓ The complete thyroid panel: TSH, fT4, fT3, rT3, TPO-Ab, TG-Ab — what to order and why ✓ Thyroid and VO2max, strength, body composition, cardiovascular function — the performance mechanisms ✓ Hypothyroid symptom checklist and the outer-third eyebrow test ✓ Hashimoto’s thyroiditis: autoimmune management with selenium, Vitamin D, and lifestyle ✓ Subclinical hypothyroidism: the grey zone that standard testing misses ✓ The conversion problem: how cortisol, caloric restriction, and selenium deficiency suppress fT3 ✓ Nutrition for thyroid health: iodine, selenium, zinc, iron, tyrosine — with specific doses ✓ Postpartum thyroiditis and thyroid across the lifespan ✓ Body temperature as a thyroid proxy — how to track BBT and interpret it ✓ Supplement evidence: ashwagandha (specific thyroid RCT data), selenium, zinc, Vitamin D ✓ Levothyroxine vs T3 combination vs DTE — the medical management options explained ✓ The 12-Week Thyroid Optimisation Protocol with month-by-month tracking calendar ✓ Thyroid-hormone interaction guide for cortisol, testosterone, oestrogen, and insulin

Who Is This For

Anyone experiencing unexplained fatigue, brain fog, weight gain despite diet and exercise, slow training adaptation, cold intolerance, hair thinning, or cognitive slowing — particularly those who have been told their thyroid is “normal.”

========================================== HPS G5 — The Insulin Intelligence Guide PRODUCT TITLE: The Insulin Intelligence Guide PRICE: $47 CATEGORY: Performance SHORT DESCRIPTION: The complete evidence-based guide to insulin — metabolic flexibility, insulin resistance, performance nutrition timing, CGM interpretation, and the 12-week insulin optimisation protocol. ========================================== LONG DESCRIPTION:

Insulin resistance is not a disease waiting to happen. It is a performance impairment happening now.

The Insulin Intelligence Guide is the final and foundational guide in the Hormonal Performance Series — because insulin is the metabolic context in which all four preceding hormones (cortisol, testosterone, oestrogen, thyroid) operate. Insulin is the most anabolic hormone in the human body. It drives muscle protein synthesis, glycogen storage, fat metabolism, and brain glucose signalling. When insulin resistance develops, every system slows: body composition stops responding, training adaptation blunts, cognition dulls, and hormonal optimisation becomes significantly harder.

What’s Inside (60+ Pages)

✓ Insulin physiology: beta cells, GSIS, the signalling cascade, and GLUT4 — the molecule that determines insulin sensitivity ✓ The biphasic insulin response: why the first-phase response is the most sensitive early marker of insulin resistance ✓ Metabolic flexibility: the capacity to switch between fat and glucose — how to test it and how to build it ✓ Insulin resistance mechanisms: IRS-1 serine phosphorylation, visceral fat, inflammation, and the self-perpetuating cycle ✓ CGM interpretation: post-meal peaks, time in range, glycaemic variability, dawn phenomenon — the complete practical guide ✓ HOMA-IR, fasting insulin, HbA1c, triglycerides — the complete metabolic assessment panel ✓ The food order effect: the 20-40% glucose spike reduction from eating vegetables and protein before carbohydrates ✓ Time-restricted eating protocols: 12:12, 14:10, 16:8 — evidence, implementation, and performance considerations ✓ Exercise for insulin sensitivity: Zone 2, HIIT, resistance training — specific protocols and post-meal walking ✓ Berberine, inositol, alpha-lipoic acid, chromium, Ceylon cinnamon — the supplement evidence with doses ✓ PCOS and insulin: the specific management approach with inositol evidence ✓ Brain insulin resistance and the Type 3 Diabetes concept — cognitive performance implications ✓ Insulin across the lifespan: decade-by-decade risks and interventions ✓ The 12-Week Insulin Optimisation Protocol with food-by-food glycaemic reference

Who Is This For

High-performers experiencing post-meal energy crashes, afternoon cognitive fog, body fat that does not respond to diet and exercise, slow training adaptation, carbohydrate cravings, or any of the other markers of metabolic inflexibility.

========================================== HPS BUNDLE — Complete Hormonal Performance Series PRODUCT TITLE: Hormonal Performance Series — Complete Bundle (All 5 Guides) PRICE: $197 (saving $38 vs individual) CATEGORY: Performance SHORT DESCRIPTION: All five guides in the Hormonal Performance Series — the complete evidence-based system for optimising cortisol, testosterone, oestrogen, thyroid, and insulin for peak human performance. ========================================== LONG DESCRIPTION:

Five hormones. One integrated system. Your complete performance edge.

The Hormonal Performance Series Complete Bundle gives you all five evidence-based guides in the series — covering every major hormonal performance variable from stress response to metabolic health, integrated into one comprehensive system.

What’s Included

📘 Guide 1: The Cortisol Code — Master your stress hormone. The HPA axis, the Cortisol Awakening Response, the lifestyle stack, and the 12-Week Cortisol Optimisation Protocol.

📘 Guide 2: The Testosterone Blueprint — Optimise your most anabolic hormone. For men and women. Sleep, training, nutrition, supplementation, and TRT decision framework.

📘 Guide 3: The Oestrogen Effect — Harness your hormonal advantage. Cycle-informed performance, perimenopause navigation, HRT evidence, and the female performance protocol.

📘 Guide 4: The Thyroid Performance Protocol — Unlock your metabolic engine. Complete thyroid testing, the conversion problem, Hashimoto’s management, and thyroid-hormone integration.

📘 Guide 5: The Insulin Intelligence Guide — Master your metabolic hormone. Metabolic flexibility, CGM interpretation, insulin resistance reversal, and the complete performance nutrition system.

Why the Bundle

Each guide stands alone. But together, they are exponentially more powerful — because each hormone interacts with the others. Cortisol suppresses testosterone. Testosterone improves insulin sensitivity. Oestrogen upregulates GLUT4. Thyroid hormones need adequate insulin signalling for conversion. Understanding how these systems interact — through the integration chapters in each guide — produces a complete hormonal performance framework that no single guide can provide.

Total Value: 300+ pages of evidence-based performance content
