Overview
The FIT Stack pairs CJC-1295 and Ipamorelin (10 mg pre-mixed) — the most widely used growth hormone secretagogue combination in peptide research. This GHRH + GHRP pairing is considered the gold standard for researchers studying natural GH optimization because it produces synergistic release without the appetite or cortisol side effects associated with older secretagogues like GHRP-6.
CJC-1295 is a modified Growth Hormone Releasing Hormone (GHRH) analog with an extended half-life (~30 minutes for the no-DAC form). It raises baseline GH output by mimicking the body's own GHRH signaling. Ipamorelin is a selective Growth Hormone Releasing Peptide (GHRP) that triggers discrete GH pulses by activating ghrelin receptors — without stimulating appetite, ACTH, or cortisol.
The combination produces GH release significantly greater than either compound alone: CJC-1295 raises the "floor" while Ipamorelin adds "spikes", closely mimicking the natural pulsatile GH pattern that peaks during deep sleep.
Why this combination works
GHRH and GHRP act on different receptors via different mechanisms, producing a well-documented synergistic effect on GH release. CJC-1295 (GHRH analog) stimulates the pituitary to produce GH by activating GHRH receptors — it sets a higher baseline. Ipamorelin (GHRP) activates ghrelin/GHS receptors to trigger acute GH pulses on top of that elevated baseline. Research consistently shows the combined GH output exceeds the sum of each compound individually — a true 1+1=3 synergy. Critically, Ipamorelin is the most selective GHRP available, meaning it boosts GH without the cortisol, prolactin, or appetite increases seen with GHRP-2 or GHRP-6.
What's inside
CJC-1295
~30 min (no DAC) / ~6-8 days (with DAC) half-lifeModified GHRH analog that raises baseline GH output via sustained GHRH receptor activation. Sets the "floor" for the synergistic GH release pattern.
Ipamorelin
~2 hours half-lifeSelective GHRP that triggers acute GH pulses via ghrelin receptor activation — without cortisol, prolactin, or appetite side effects. Adds "spikes" on top of CJC's elevated baseline.

- Typically dosed before bed to align with natural GH peak
Dosing & reconstitution
Research dosing
Standard research protocols use 100-300 mcg of each compound, administered subcutaneously 1-3 times daily. The most common protocol is a single daily injection 30-60 minutes before bed (aligning with the natural nocturnal GH pulse). Some protocols add a second dose upon waking or pre-workout. Cycles typically run 8-12 weeks. Avoid eating for 30 minutes before and after injection, as insulin spikes can blunt GH release.
Reconstitution
Add 2 mL of bacteriostatic water to the 10 mg vial for a 5 mg/mL concentration. A 200 mcg dose (100 mcg of each compound) equals 0.04 mL or 4 units on a U-100 insulin syringe. Inject water slowly along the vial wall, swirl gently. Do not shake.

Why CJC-1295 without DAC for this stack?
The no-DAC form (also called Modified GRF 1-29) has a ~30 minute half-life, which produces cleaner GH pulses that better mimic natural physiology. The DAC (Drug Affinity Complex) version extends the half-life to ~8 days, which creates a sustained GH elevation rather than pulses. Most researchers prefer the pulsatile pattern for cleaner signaling.
Should I avoid food around injection time?
Yes — insulin and GH have an inverse relationship. Eating within ~30 minutes of injection triggers an insulin response that can blunt GH release by 50-70%. Most protocols recommend injecting on an empty stomach, typically before bed or first thing in the morning.
How does this compare to actual HGH (somatropin)?
Exogenous HGH directly provides the hormone, bypassing the pituitary. CJC-1295 + Ipamorelin stimulate your own pituitary to produce GH naturally — the release pattern is pulsatile rather than flat, which better preserves the feedback loop. The GH elevation is more modest than exogenous HGH but avoids many of its side effects (water retention, joint pain, insulin resistance).
