Tesamorelin + Ipamorelin (Tesamorelin/Ipamorelin Combination)

Category: Growth Hormone. Status: Compounded combination.

A synergistic combination of tesamorelin (GHRH analog) and ipamorelin (selective GHRP) that produces robust, pulsatile growth hormone release. The GHRH+GHRP pairing creates a multiplicative GH response greater than either compound alone.

How it works

Tesamorelin stimulates GH release by activating GHRH receptors on pituitary somatotrophs. Ipamorelin amplifies the pulse by acting on ghrelin/GHS receptors. Together they produce a synergistic "1+1=3" GH release while maintaining physiological pulsatility.

Key facts

  • Molecular weight: Blend
  • Half-life: Tesamorelin: ~26 min; Ipamorelin: ~2 hours. Combined peak GH at 30-60 min post-injection.
  • Bioavailability: High (subcutaneous)
  • Storage: Refrigerated at 2-8C after reconstitution.

Dosing overview

  • Typical dose: Tesamorelin 1-2 mg + Ipamorelin 200-300 mcg
  • Frequency: Once daily (before bed) or twice daily
  • Duration: 3-6 months
  • Route: Subcutaneous injection

Protocol notes

  • Standard: Inject combined dose 30-60 min before bed on empty stomach.
  • Advanced: Split into AM (fasted) and PM (pre-bed) doses.
  • Run continuously for 3-6 months for body composition benefits.
  • Some cycle 5 days on / 2 days off.

Reported benefits

  • Significant fat loss (especially visceral/abdominal)
  • Lean muscle gains
  • Improved sleep quality
  • Enhanced recovery
  • Anti-aging effects
  • Better body composition without exogenous HGH side effects

Possible side effects

  • Injection site reactions
  • Mild water retention
  • Numbness/tingling (transient)
  • Increased hunger (mild)
  • Headache (uncommon)

Research

  • GHRH + GHRP synergy on GH release (2014): Combined GHRH + GHRP administration produced 3-5x greater GH release than either peptide alone in healthy adults.
  • Tesamorelin/Ipamorelin body composition (2022): Combination therapy for 12 weeks reduced visceral fat by 15-20% and increased lean mass in GH-deficient adults.

  • reconstitute_ron rated it 5/5 - Sleep quality improvement was the first thing I noticed: Running Tesamorelin + Ipamorelin for 2 months now, primarily for recovery and body composition. The first benefit I noticed was dramatically better sleep, deeper and more restorative, within the first week. Body composition changes came slower but are real. Leaner midsection, slightly fuller muscles, and my recovery between training sessions is noticeably improved. Not dramatic bodybuilder gains, more like everything works a bit better. Side effects have been minimal. Some water retention in the first 2 weeks that settled down, and occasional numbness in my fingers in the morning that goes a
  • evidence_eli rated it 5/5 - Better recovery and deeper sleep at 2 months: Tesamorelin + Ipamorelin has been a solid addition to my protocol. The GH release translates to better sleep, improved recovery, and a gradual improvement in body composition that I did not get from training alone. I track my sleep with a wearable and my deep sleep percentage went from 12% to about 18-20% within the first two weeks. That alone is worth it for recovery. The body comp changes are more subtle but visible in progress photos over 2-3 months. No significant side effects at the doses I am running. Occasionally wake up with slightly puffy hands but it resolves within an hour. Recomm

  • compound_curious rated it 5/5 - Body comp changes subtle but real: About 2 weeks into my Tesamorelin + Ipamorelin protocol and the compound is doing what it is supposed to. Sleep is deeper, skin quality is better, fat around the midsection is slowly reducing, and my recovery from training is improved. The key insight I have learned is patience. This is not an overnight transformation. It is a slow, steady optimization that compounds over weeks and months. People who quit after 2 weeks are not giving it enough time. Only downsides: some mild joint stiffness early on (actually a sign it is working) and the fasted dosing schedule is sometimes inconvenient. Wor
