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

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
