GHRH + GHRP Dual-Pathway GH Protocol
A precision combination of two complementary GH-axis peptides: Tesamorelin (a GHRH analogue) stimulates the pituitary via the hypothalamic pathway, while Ipamorelin (a selective GHRP) amplifies GH release via the ghrelin receptor — producing a synergistic pulse significantly greater than either alone.

This protocol pairs two peptides that act on completely separate receptors of the growth hormone axis — creating a compounding effect that neither can achieve alone. Tesamorelin is a stabilized GHRH analogue that binds to the pituitary's GHRH receptors, signaling the release of endogenous GH in a pulsatile, physiologically normal pattern. Ipamorelin is a highly selective growth hormone releasing peptide (GHRP) that binds ghrelin receptors, adding a second, independent GH stimulation signal simultaneously.
The result is a larger, cleaner GH pulse than either peptide generates solo — without meaningfully raising cortisol, prolactin, or other hormones that less selective GHRPs can affect. The combination preserves the body's own negative feedback mechanisms and avoids the receptor downregulation associated with exogenous growth hormone administration.
This dual-pathway protocol is well-regarded in the longevity and performance space for producing noticeable improvements in body composition, recovery speed, sleep depth, and energy — while remaining within the body's natural hormonal architecture.
Tesamorelin binds to GHRH receptors on pituitary somatotroph cells, triggering synthesis and pulsatile release of endogenous growth hormone. Its stabilized structure gives it a longer active half-life than natural GHRH, with an extensive clinical evidence base including FDA-approved studies on visceral fat reduction. It works with the body's own feedback loop, preventing supraphysiological GH elevation.
Ipamorelin is a third-generation GHRP with exceptional selectivity. It binds ghrelin receptors in both the pituitary and hypothalamus, stimulating GH release through a completely separate mechanism from GHRH. Critically, Ipamorelin produces minimal impact on cortisol or prolactin — a significant advantage over older GHRPs. Its selective, clean GH pulse makes it the preferred pairing for GHRH-based protocols.
When GHRH and GHRP signals arrive at the pituitary simultaneously, the resulting GH pulse is significantly larger than the additive effect of each alone — a well-characterized synergy in GH physiology. Tesamorelin provides the primary hypothalamic signal; Ipamorelin amplifies and extends it via the ghrelin pathway. The combination also suppresses somatostatin (the GH-inhibiting hormone) more effectively than either alone, creating a longer and more complete GH secretory window.
Tesamorelin / Ipamorelin is administered via subcutaneous injection, typically once daily in the evening to align with the natural nocturnal GH pulse. Some protocols use twice-daily dosing for enhanced results. The appropriate dosage, frequency, and protocol duration is determined through the BRAVO1 physician review process based on your individual health profile, goals, and baseline labs.
