Tesamorelin-Ipamorelin Blend

Tesamorelin-Ipamorelin Blend

Quick Facts

  • Full Name: Tesamorelin + Ipamorelin Combined GH Stack
  • Type: Dual-mechanism GH axis stimulation blend (GHRH + GHRP)
  • Category: GH Axis / Fat Loss / Muscle / Anti-Aging / Sleep
  • Components:
    • Tesamorelin — FDA-approved GHRH analog (stabilized, longer-acting)
    • Ipamorelin — selective GHRP/ghrelin mimetic (cleanest GHRP profile)
  • Typical Dose: 1–2 mg Tesamorelin + 100–300 mcg Ipamorelin daily
  • Administration: Subcutaneous injection (often combined in single syringe)
  • Status: Tesamorelin FDA-approved (Egrifta, HIV lipodystrophy); Ipamorelin Research Only
  • WADA Status: Both Prohibited (S2)

What It Does

This combination represents the "gold standard" dual-stimulation approach to GH axis optimization — targeting both GHRH receptors (via Tesamorelin) and ghrelin receptors (via Ipamorelin) simultaneously. Since GHRH and GHRP act through independent pathways that converge on somatotroph cells, their combination produces a supra-additive GH pulse: significantly greater than either alone. Tesamorelin is favored over Sermorelin or CJC-1295 for its FDA-approved status, excellent stability, and clinical evidence for visceral fat reduction. Ipamorelin is favored as the GHRP component for its clean safety profile (minimal cortisol/prolactin elevation).

Component Overview

Tesamorelin Contribution

  • Stabilized GHRH analog with trans-3-hexenoic acid modification → longer half-life vs. Sermorelin
  • FDA-approved for HIV-associated lipodystrophy → significant clinical evidence base
  • Stimulates pulsatile GH release from somatotrophs via GHRH receptor
  • Reduces visceral adipose tissue (VAT) — strongest clinical evidence of any GH secretagogue

Ipamorelin Contribution

  • Selective GHS-R1a agonist (ghrelin mimetic) — pentapeptide
  • Cleanest GHRP profile: minimal cortisol, prolactin elevation vs. GHRP-2, GHRP-6, Hexarelin
  • No significant appetite stimulation (unlike GHRP-6)
  • Amplifies GH pulse amplitude and duration beyond GHRH alone
  • Complements Tesamorelin's GHRH action for supra-additive effect

Dosing Protocols

Standard Daily Protocol

  • Tesamorelin: 1–2 mg SubQ once daily
  • Ipamorelin: 100–300 mcg SubQ once daily
  • Timing: Bedtime (aligns with natural GH pulse; Ipamorelin especially effective at night)
  • Can combine: In same syringe at time of injection
  • Fasted: Inject in fasted state for maximal GH response (avoid injection within 2 hours of carbohydrate meal)
  • Duration: 3–6 months; some use continuously at lower doses
  • Source: The Peptides Bible, Peptides Made Easy

Fat Loss Emphasis Protocol

  • Tesamorelin: 2 mg/day (full FDA lipodystrophy dose)
  • Ipamorelin: 200–300 mcg/day
  • Duration: 6 months minimum for visceral fat reduction
  • Monitor IGF-1 at 6–8 weeks; target upper third of normal range

Anti-Aging / Sleep Protocol

  • Tesamorelin: 1 mg at bedtime
  • Ipamorelin: 100–200 mcg at bedtime
  • Focus on sleep quality, recovery, and GH restoration

Stacks Well With

  • MK-677 – oral GH secretagogue to extend tonic GH elevation alongside pulsatile injection
  • IGF-1 LR3 – downstream anabolic amplification
  • PEG-MGF – local muscle repair in combination with systemic GH elevation
  • DSIP – sleep architecture complement to bedtime GH stack

Use Cases

  • GH Axis Optimization (age-related GH decline, functional GH deficiency)
  • Visceral Fat Reduction (Tesamorelin's primary clinical indication)
  • Body Composition (lean mass, fat loss)
  • Sleep Quality and recovery
  • Anti-Aging
  • HIV Lipodystrophy (Tesamorelin FDA-indicated)
  • Metabolic Health (GH-mediated insulin sensitivity improvements)

Contraindications & Safety

  • Active malignancy — GH axis stimulation; avoid
  • Hypothyroidism — correct first; blunts response
  • Diabetes / insulin resistance — GH can raise blood glucose; monitor
  • Sleep apnea — GH elevation may worsen; screen
  • Fluid retention — especially at higher Tesamorelin doses
  • Ipamorelin's clean profile minimizes cortisol/prolactin concerns vs. other GHRPs
  • Individual component contraindications apply — see Tesamorelin, Ipamorelin

Storage

  • Tesamorelin lyophilized: -20°C long-term; 2–8°C up to 3 months
  • Ipamorelin lyophilized: -20°C long-term; 2–8°C up to 3 months
  • Reconstituted: Each at 2–8°C for 2–4 weeks; protect from light
  • Mixing: Combine in same syringe at injection time; do not premix and store
