Growth hormone secretagogue
CJC-1295 (no DAC) + Ipamorelin blend
The classic growth-hormone stack in one vial: a GHRH fragment with a secretagogue, unapproved and prohibited in sport.
What it is
A prepackaged mixture of mod GRF 1-29 — the short-acting GHRH analogue — and ipamorelin, usually 5 mg of each. The pairing is popular because the two act on different receptors in the same growth-hormone pathway. Neither is an approved medicine, the combination has not been tested in a controlled human trial, and both are prohibited in sport.
How it works
- 1
The GHRH fragment binds pituitary GHRH receptors, priming growth-hormone release.
- 2
Ipamorelin acts on the ghrelin receptor, GHS-R1a, to trigger the release itself.
- 3
Together they are said to produce a larger pulse than either alone — shown in growth-hormone testing, but never linked to a proven body-composition or recovery outcome.
- 4
Both are short-acting, so a dose produces a brief pulse rather than sustained elevation.
- 5
IGF-1 rises secondarily with repeated use.
What it's studied for
Reported and studied effects
- A measurable growth-hormone pulse after dosing
- Modest IGF-1 increase with repeated use
- Reported improved sleep and recovery from user accounts
- Fluid retention and joint stiffness, as with the growth-hormone class
Research protocol notes
Research context onlyResearch context only — no approved protocol exists. Community schedules use roughly 200 micrograms of each peptide once or twice daily, cycling 8–12 weeks on with 2–4 weeks off; 12 syringe units from a 3 ml reconstitution is a common vendor figure. None of this has been evaluated in a trial, and units depend on the exact concentrations in the vial.
These figures are described so you can understand what researchers did. They are not a dose, a schedule, or a suggestion — and they are not a substitute for a doctor.
Possible side effects and contraindications
Safety profile
Possible side effects
- Headache, flushing and dizziness
- Water retention and joint aches
- Tingling or numbness in the hands
- Increased appetite
- Unknown long-term effects of chronic IGF-1 elevation
Contraindications and cautions
- Cancer history or active malignancy
- Diabetes or impaired glucose tolerance
- Pregnancy, breastfeeding and childhood
- Prohibited in competitive sport
A side-effect list is never complete, and these are not the only situations that warrant caution. Anything unexpected, or anything you are unsure about, should be discussed with a doctor before use.
Evidence assessment
Small studies document growth-hormone release from the individual peptides, but no trial has examined the blend or any of the outcomes it is sold for.
