Tesa/IPA Protocol

Tesamorelin + Ipamorelin GH Secretagogue Blend

Human clinical
research use only

The Tesa/IPA blend combines two complementary growth hormone secretagogues: Tesamorelin (a GHRH analog that stimulates GH release from the pituitary) and Ipamorelin (a selective ghrelin mimetic/GHRP that amplifies GH pulses). This combination addresses both the GHRH and GHRP pathways for synergistic GH release. Common formulations include 5mg/5mg (1:1 ratio) and 10mg/3mg (higher Tesamorelin) variants. Tesamorelin is FDA-approved for HIV-associated lipodystrophy, while Ipamorelin remains investigational.

Overview

The Tesa/IPA blend combines two complementary growth hormone secretagogues: Tesamorelin (a GHRH analog that stimulates GH release from the pituitary) and Ipamorelin (a selective ghrelin mimetic/GHRP that amplifies GH pulses). This combination addresses both the GHRH and GHRP pathways for synergistic GH release. Common formulations include 5mg/5mg (1:1 ratio) and 10mg/3mg (higher Tesamorelin) variants. Tesamorelin is FDA-approved for HIV-associated lipodystrophy, while Ipamorelin remains investigational.

The blend leverages two distinct GH-releasing pathways: Tesamorelin is a synthetic GHRH analog that directly stimulates growth hormone-releasing hormone receptors on pituitary somatotrophs, triggering GH synthesis and secretion in a pulsatile, physiological manner. Ipamorelin is a selective ghrelin receptor (GHS-R1a) agonist that amplifies GH pulses without significantly affecting cortisol or prolactin. Together, they produce synergistic GH release greater than either compound alone, while maintaining the body's natural feedback mechanisms.

FAQ

Why combine tesamorelin and ipamorelin instead of using them separately?

Tesamorelin and ipamorelin work on complementary GH-release pathways (GHRH vs GHRP receptors), producing synergistic GH release greater than either alone. The combination mimics natural pulsatile GH secretion more effectively while maintaining safety with less cortisol/prolactin elevation than GHRPs used solo.

What's the ideal 5/5 vs 10/3 ratio for Tesa/IPA and when to use each?

5/5 (equal parts) provides balanced GH stimulation suitable for general recovery. The 10/3 (higher tesamorelin) variant emphasizes visceral fat loss and metabolic effects. Choose 5/5 for athletic recovery; 10/3 for fat-loss focused protocols with body composition optimization goals.

Should the Tesa/IPA blend be taken on an empty stomach?

Yes, both tesamorelin and ipamorelin work best on an empty stomach (2-3 hours before eating). Evening injection (before bed) on an empty stomach optimizes the protocol by aligning with natural nighttime GH pulses and avoiding food-induced metabolic interference.

Can Tesa/IPA be combined with CJC-1295 or other GH secretagogues?

No, combining Tesa/IPA (which already contains both GHRH and GHRP pathways) with additional GHRPs or GHRH analogs risks excessive pituitary stimulation. The blend is specifically designed as a complete dual-pathway system that shouldn't require additional GH secretagogues.
