⟁ V-Series Protocol
Natural GH-pathway optimization, without exogenous GH risks
Every component is individually sourced and third-party verified. Tap any compound for its full clinical reference.
A stack for lean muscle, recovery and deeper sleep. CJC-1295 and Ipamorelin together support the body's own growth hormone release.
CLINICAL INDICATION: Healthy adults pursuing body-composition or recovery optimization; not for diagnosed GH deficiency (different therapy class) and not for muscle-mass claims
CJC-1295 (No DAC) extends the GHRH-receptor signal; Ipamorelin acts through the ghrelin/GHS-R pathway with minimal cortisol or prolactin effect. The two pathways converge on amplified endogenous GH pulses, measured downstream by IGF-1. The stack does not introduce exogenous GH; it modulates the body's own secretion pattern.
A deliberately conservative GH-axis stack: two compounds, complementary mechanisms, no redundancy. Designed for patients who want measurable IGF-1 optimization with the cleanest possible monitoring picture - not a multi-compound protocol whose individual contributions cannot be disentangled.
A note for patients already on a SERM (e.g. enclomiphene or clomiphene): SERMs can modestly lower IGF-1 - recent data found reduced IGF-1 in most treated men (Mogar et al., J Endocr Soc 2025) - so some patients on SERM therapy consider a GH-axis stack like this one to offset that dip. If this applies to you, it is a monitoring consideration to raise with your own doctor, not a self-directed protocol: Vivre does not supply enclomiphene, and whether the two are appropriate together (and at what point IGF-1 is read. Your IGF-1 here would be interpreted against the SERM rather than in isolation.

These protocols gently restore your body’s own pulsing release of growth hormone rather than replacing it. Because growth hormone also affects blood sugar, monitoring confirms two things: that it is working, and that it is doing so safely.
Incremental approach. Vivre starts below the standard dose and advances only on tolerance. This monitoring is the safety scaffold for that conservative approach.

Two randomized, placebo-controlled, double-blind ascending-dose trials in healthy adults aged 21–61 (DOI 10.1210/jc.2005-1536). A single subcutaneous injection produced dose-dependent increases in mean plasma GH (2–10× for ≥6 days) and IGF-I (1.5–3× for 9–11 days); estimated half-life 5.8–8.1 days. After multiple doses, mean IGF-I stayed above baseline up to 28 days, with evidence of cumulative effect. No serious adverse reactions; well tolerated at 30–60 μg/kg. CRITICAL FRAMING: the studied agent was the DAC-modified long-acting variant, which produces SUSTAINED (continuous) GH/IGF-I elevation. Vivre uses the No-DAC (Mod GRF 1-29) form, which has a ~30-minute half-life and produces PULSATILE GH release that better mimics physiology. This study supports the GH-axis mechanism but does not endorse continuous-elevation (DAC) dosing for longevity use.
View on publisher ↗Foundational preclinical and early clinical study establishing Ipamorelin's selectivity profile. In swine, no GH secretagogue tested affected FSH, LH, PRL, or TSH plasma levels - but GHRP-6 and GHRP-2 elevated ACTH and cortisol meaningfully, while Ipamorelin did not (even at doses 200-fold above the ED50 for GH release). This selectivity is the principal clinical reason Ipamorelin is preferred in modern GH-axis stacks over earlier GHRPs.
View on publisher ↗Preclinical rat study examining downstream skeletal effects of Ipamorelin-driven GH release. Demonstrated dose-dependent increases in longitudinal bone growth via the GH/IGF-1 axis. Important methodology framing: rat model with pre-pubertal skeletal growth - does not translate directly to adult human use, but supports the IGF-1 elevation mechanism that anchors body-composition and recovery applications.
