Tesa 10mg/Ipa 3mg
Tesa/IPA peptide is a research-grade blend of tesamorelin and ipamorelin designed to stimulate growth hormone release through complementary pathways.
Overview
Tesa/IPA peptide combines tesamorelin, a growth hormone-releasing hormone (GHRH) analog, with ipamorelin, a selective ghrelin receptor agonist, into a single formulation for research purposes www.realpeptides.co+1. Tesamorelin activates GHRH receptors in the anterior pituitary, initiating pulsatile growth hormone (GH) secretion, while ipamorelin binds to ghrelin receptors (GHSR-1a) on somatotroph cells, amplifying GH pulse amplitude and suppressing somatostatin, the hormone that normally inhibits GH release www.realpeptides.co+1. This dual-pathway approach produces a more robust and physiologically normal GH pulse than either peptide alone peptide-db.com.
Mechanism of Action
- Tesamorelin: A 44-amino-acid synthetic analog of GHRH, tesamorelin binds to GHRH receptors on pituitary somatotrophs, triggering cyclic AMP (cAMP) production and stimulating GH synthesis and secretion in a pulsatile manner. Its half-life is approximately 26–38 minutes, mimicking natural GH rhythms www.realpeptides.co+1.
-
Ipamorelin: A pentapeptide ghrelin mimetic, ipamorelin selectively activates GHSR-1a receptors, enhancing GH pulse amplitude and extending secretion duration by inhibiting somatostatin. Its half-life is around 2 hours, providing a longer window of GH stimulation www.realpeptides.co+1.
The combination leverages synergy: tesamorelin initiates the GH pulse, and ipamorelin amplifies and prolongs it, resulting in GH area-under-the-curve (AUC) elevations 1.8–2.5 times greater than single-agent protocols at equivalent doses www.realpeptides.co+1.
Research and Applications
Tesa/IPA peptide is primarily used in preclinical and clinical research to study:
- GH pulsatility and secretion patterns
- Body composition and fat metabolism
- Metabolic function and IGF-1 modulation
Tesamorelin is FDA-approved for HIV-associated lipodystrophy (brand name Egrifta), providing a clinical evidence base, while ipamorelin remains investigational puretestedpeptides.com+1. The blend is not approved for general therapeutic use outside research contexts.
Practical Considerations
- The blend is supplied as a pre-mixed lyophilized peptide, reducing reconstitution errors and ensuring precise dosing www.realpeptides.co.
- Administration is typically subcutaneous, often timed to align with natural GH pulses (e.g., before sleep or on an empty stomach) to optimize physiological effects peptide-db.com.
- Proper handling, storage, and reconstitution are critical to maintain peptide stability and potency puretestedpeptides.com.
In summary, Tesa/IPA peptide is a dual-pathway GH secretagogue blend that combines the pulse-initiating effects of tesamorelin with the pulse-amplifying effects of ipamorelin, making it a valuable tool in research on growth hormone physiology, metabolic health, and body composition www.realpeptides.co+1.
