GH Optimisation

Stack: CJC-1295 + Ipamorelin · gh-axis optimisation
"The default GH stack. The additive-GH biomarker data is fair; the body-composition and anti-ageing outcomes are oversold relative to what's been shown."

US clinic · off-label compounding
Where / who
US functional-medicine, longevity & sports-medicine clinics — physician-prescribed via 503A/503B compounding pharmacies.
Track record
CJC-1295 / Ipamorelin: among the most commonly compounded peptides in US clinics until the Sept 2023 FDA Category 2 listing; removed from Category 2 Apr 2026, 503A Bulks List decision pending the PCAC meeting 23–24 Jul 2026.
Evidence it adds
Real-world clinical observation — physician-charted, supervised use. A genuine evidence tier, but observational: uncontrolled, unpublished, no registry, outside formal pharmacovigilance.
What it means
Off-label compounding under prescription — never an FDA-approved therapy. Removal from Category 2 is not approval.
Basis: US compounding-pharmacy practice · FDA Docket FDA-2025-N-6895
No approved clinical use
Clinical record
No country lists this exact combination as an approved therapy.
Human trials
No completed human trial of the combination. Biomarker rise fair; outcomes oversold.
Basis required for a clinical-use tag: none found — absence shown, not hidden
Why this combination

CJC-1295 (sustained) plus Ipamorelin (pulsatile) raises GH/IGF-1 additively — that part is reasonably supported. The leap to meaningful recomposition or longevity outcomes is not well evidenced.

What's worth monitoring

With limited or no human safety data for this combination, there is no established marker set to monitor against — which is a reason for more caution, not less. Baseline bloods and a clinician conversation matter here. General information, not medical advice.

Combination evidence
Real-world uptake High

The default GH stack in clinics and community.

Human efficacy Weak

Biomarker rise fair; outcomes oversold.

Clinical observation Observational

A decade-plus of physician-supervised, charted use — meaningful real-world signal, with no commonly-reported serious adverse-event pattern. But uncontrolled, unpublished, held in private charts (no registry) and outside formal pharmacovigilance. Not controlled evidence.

The honest ceiling

Solid on biomarkers, thin on outcomes.
