BeaCapra CJC-1295 / Ipamorelin Blend — The Peak Stack
Frequently Bought Together
The Peak Stack: Premier Growth Hormone Research Combination
The BeaCapra Peak Stack combines CJC-1295 no DAC (5mg) and Ipamorelin (5mg) in a single 10mg lyophilized blend—the most widely researched growth hormone peptide combination in the field. This precision formulation targets two complementary GH release mechanisms: GHRH receptor activation (CJC-1295) and ghrelin receptor agonism (Ipamorelin). Each vial is verified at ≥99% purity by HPLC and mass spectrometry.
Published research demonstrates that combining a GHRH analog with a GH secretagogue produces synergistic GH release significantly greater than either peptide alone. CJC-1295 amplifies the GHRH pulse signal while Ipamorelin provides the ghrelin-mediated release trigger, resulting in enhanced amplitude and duration of GH pulses while maintaining the natural pulsatile release pattern.
The Peak Stack is designed for researchers investigating growth hormone axis optimization, age-related GH decline, body composition changes, and metabolic regulation. The combined formulation simplifies multi-peptide protocols and ensures consistent co-administration ratios across study cohorts.
Storage: Store lyophilized peptide at -20°C. Reconstitute with bacteriostatic water and store at 2-8°C. Use within 30 days. Protect from light.

Research Benefits
- Synergistic GH Stimulation: Combines GHRH analog (CJC-1295) with a selective GHRP (Ipamorelin) for amplified, physiological growth hormone release through dual-pathway activation
- Pulsatile GH Release: Research demonstrates more natural GH secretion patterns compared to single-agent protocols, mimicking endogenous pulsatility
- IGF-1 Elevation: Combined action produces sustained IGF-1 elevation through both direct GH stimulation and extended GHRH receptor activation
- Body Composition Research: Investigated for favorable changes in lean mass and adipose tissue ratios without significant effects on cortisol or prolactin
- Sleep Architecture: Studies suggest enhanced slow-wave sleep duration, aligning with the natural nocturnal GH pulse
Mechanism of Action
This combination activates two complementary pathways in the GH axis:
CJC-1295 (GHRH Analog)
- Binds GHRH receptors on somatotroph cells in the anterior pituitary
- Stimulates cAMP/PKA signaling cascade for GH gene transcription and release
- No-DAC version provides pulsatile stimulation without sustained receptor activation
Ipamorelin (Selective GHRP)
- Activates ghrelin/GHS-R1a receptors on somatotrophs through a separate signaling pathway
- Highly selective for GH release without significant cortisol, prolactin, or appetite stimulation
- Amplifies CJC-1295's signal through receptor crosstalk and intracellular signaling convergence
The dual-pathway activation produces greater GH release than either peptide alone, while Ipamorelin's selectivity maintains a clean hormonal profile without the side effects associated with less selective GHRPs.
Research Protocol
For research purposes only. Not for human consumption.
- Typical Research Dose: 100-300 mcg CJC-1295 + 100-300 mcg Ipamorelin per administration
- Administration: Subcutaneous injection
- Timing: Pre-sleep administration in most protocols to synergize with natural nocturnal GH pulsatility
- Research Cycle: 8-12 week protocols commonly reported
- Frequency: 1-3 times daily depending on study objectives; once pre-sleep is most common
Reconstitution
- Reconstitute with bacteriostatic water; gently swirl
- Both peptides co-lyophilized for convenient single reconstitution
- Refrigerate at 2-8 °C; use within 30 days
Safety & Storage
- Lyophilized: -20 °C long-term; 2-8 °C up to 6 months
- Reconstituted: 2-8 °C; use within 30 days
- Protect from light and temperature fluctuations
Research Considerations
- Ipamorelin's selectivity minimizes cortisol and prolactin elevation compared to GHRP-6 or GHRP-2 combinations
- Fasting state during administration may enhance GH response; glucose and fatty acids blunt GH secretion
- Long-term GH elevation protocols require monitoring of IGF-1 levels and glucose homeostasis
- Not recommended with somatostatin analogs (opposing mechanism)
- For research use only
Frequently Asked Questions
-
Why combine CJC-1295 with Ipamorelin?
They activate separate receptor pathways on the same pituitary cells, producing synergistic GH release. CJC-1295 provides the GHRH signal while Ipamorelin amplifies it through ghrelin receptor activation, with the added benefit of Ipamorelin's clean selectivity profile.
-
Is this the DAC or no-DAC version of CJC-1295?
BeaCapra's blend uses CJC-1295 without DAC (Drug Affinity Complex), providing pulsatile rather than sustained GH stimulation for a more physiological release pattern.
-
Why is pre-sleep dosing preferred?
The largest natural GH pulse occurs during early slow-wave sleep. Pre-sleep administration synergizes with this endogenous rhythm, amplifying the natural peak rather than creating non-physiological daytime spikes.

What purity is this product?
≥99% purity for both peptides, verified by HPLC and mass spectrometry. COA available.
