1. Clinical Overview

Molecule: Stabilized synthetic GHRH analog, 44 amino acids, with trans-3-hexenoyl group for increased stability, half-life, and pituitary potency

Classification: Enhanced GHRH analog • Visceral-fat reduction • Anti-aging/metabolic • Cognitive support

FDA Approval: HIV-associated lipodystrophy (visceral adiposity). Egrifta®.

Stronger, longer-acting, and more targeted than Sermorelin (GRF 1–29). Off-label: visceral fat reduction in non-HIV, anti-aging, GH optimization, body recomposition, cognitive/metabolic support.

2. Mechanisms of Action

2.1 Enhanced GHRH Receptor Activation

Binds GHRH receptor on somatotrophs: ↑ GH pulse amplitude/frequency, ↑ IGF-1. Higher and more sustained GH secretion vs Sermorelin.

2.2 Preferential VAT Reduction

10–20% visceral fat reduction. Preferential organ-surrounding fat loss, reduced VAT biomarkers. GH-driven lipolysis, IGF-1 adipocyte remodeling, reduced hepatic fat.

2.3 Glucose & Lipid Metabolism

Decreased fasting triglycerides, improved lipid profile, reduced cytokines, mild glycemic improvement.

2.4 Cognition & Neuroprotection

Memory consolidation, hippocampal neurogenesis, reduced brain inflammation, cognitive performance in aging.

2.5 Anti-Aging & Repair

GH/IGF-1: collagen synthesis, tissue healing, training recovery, bone density, skin rejuvenation.

3. Clinical Applications

3.1 Visceral Fat (Primary)

Abdominal/organ-surrounding/liver fat, cardiometabolic risk. Middle-aged men, postmenopausal women, metabolic syndrome.

3.2 Body Recomposition

Lean mass retention, fat loss with muscle preservation, post-liposuction contour.

3.3 Anti-Aging & Longevity

Better sleep, recovery, energy, skin elasticity.

3.4 Cognitive Enhancement

Short-term memory, recall, spatial cognition. Age-related decline, chronic stress, poor sleep.

3.5 GH Optimization Without HGH

Preserves pulsatile GH, no endogenous suppression, minimizes overdose risk, avoids supraphysiologic IGF-1.

4. Administration & Protocols

VAT Reduction (FDA model): 2 mg SC nightly
Anti-Aging / Longevity: 1 mg SC nightly
Body Recomposition: 1–2 mg SC nightly ± SLU-PP-332, AOD-9604
Cognitive / Neuroprotection: 0.5–1 mg nightly

Cycling

VAT: 3–6 months continuous. Recomposition: 8–12 week cycles. Anti-aging: ongoing low-dose nightly.

Notes

Take at night. Avoid food 1–2 hrs pre/post (carbs/fats). Best during calorie deficit.

5. Combination Therapy (Peptide Protocol Portal Synergy)

+ CJC-1295 (No DAC): Synergistic GH-axis — strong GHRH + extended pituitary stimulation
+ Ipamorelin: Dual secretagogue — GHRH + GHRP = maximal physiologic GH
+ SLU-PP-332: Thermogenesis + GH — VAT, mitochondrial, metabolic flexibility
+ AOD-9604: Targets stubborn abdominal fat
+ BPC-157 + TB-500: Orthopedic injury/recovery
+ MOTS-c / SS-31 / NAD+: Longevity, performance, fatigue, mitochondrial optimization

6. Clinical Decision Trees

Tree 1 — Is Tesamorelin Indicated?

Excess visceral fat? → YES

Metabolic syndrome? → YES

Cognitive decline + visceral adiposity? → YES

HGH-like benefits without HGH? → YES

Active cancer? → NO

Uncontrolled diabetes? → CAUTION

Tree 2 — Dose Strategy

VAT reduction → 2 mg SC nightly

Anti-aging → 1 mg SC nightly

Cognitive → 0.5–1 mg nightly

Recomposition → 1–2 mg nightly

7. Integrated Archetypes

A — Visceral-Fat Targeting

Tesamorelin 2 mg nightly + SLU-PP-332 + AOD-9604 + low-carb nutrition
Outcome: Substantial abdominal fat reduction.

B — Longevity / Anti-Aging

Tesamorelin 1 mg nightly + NAD+ weekly + DSIP sleep + GHK-Cu skin
Outcome: Full-spectrum rejuvenation.

C — Body Recomposition

Tesamorelin 1–2 mg nightly + IGF-1 LR3 post-workout + MGF satellite-cell activation
Outcome: Lean muscle + fat loss.

D — Cognitive Enhancement

Tesamorelin 0.5–1 mg nightly + Semax/Selank + Pinealon + SS-31
Outcome: Sharper memory + neuroprotection.

8. Expected Timeline

Week 1–2: Improved sleep & recovery
Week 3–4: Reduced waist circumference
Month 2–3: 8–12% visceral fat reduction
Month 3–6: 10–20% VAT reduction, improved composition
Long-term: Stable cognitive & metabolic benefits

9. Contraindications

Absolute

  • Active cancer
  • Pregnancy / Breastfeeding

Relative

  • Uncontrolled diabetes
  • Severe liver disease
  • Active gallbladder disease
  • Pituitary tumors
  • Severe sleep apnea

10. Adverse Effects

Common: Injection-site redness, mild water retention, muscle tightness, fatigue, headache. Less common: Hyperglycemia, carpal-tunnel symptoms, peripheral edema. Rare: Elevated IGF-1, insulin resistance (high doses).

11. Monitoring

  • IGF-1 baseline & q12 weeks
  • Fasting insulin/glucose
  • Lipid profile
  • A1C (metabolic risk)
  • Waist/hip ratio
  • Body composition
  • Liver function (NASH risk)
