CJC-1295
Growth hormone & recovery








In a human clinical trial, a single dose raised growth hormone levels 2-10x and kept them elevated for up to 6 days. IGF-1 levels increased 1.5-3x over baseline.

What purity level is this?
Every batch is verified at ≥98% purity via HPLC analysis by an independent laboratory.
What is the difference between 2mg and 5mg?
Same peptide. The 5mg vial is $11.80/mg vs $19.50/mg for 2mg.
How should I store this?
Unreconstituted: -20°C. Reconstituted: 2-8°C, use within 21 days.
Is this the DAC version?
Yes. CJC-1295 with DAC (Drug Affinity Complex) via maleimidopropionic acid conjugation at Lys30, which extends the half-life.

CJC-1295
Key Benefits
Growth hormone
Clinical trial showed 2-10x GH increase from a single dose, sustained for up to 6 days.
IGF-1 levels
Increased IGF-1 levels 1.5-3x over baseline in human clinical studies.
Extended half-life
DAC modification extends half-life significantly versus native GHRH.
Human data
One of few peptides with published human clinical trial data (Teichman 2006).

Peptide science
How It Works
Step 1
Receptor binding
CJC-1295 binds to specific cell surface receptors, triggering a defined downstream signaling cascade. Each peptide targets a unique receptor profile.
Step 2
Signal activation
The receptor interaction activates intracellular pathways that regulate gene expression, protein synthesis, and cellular behavior in the target tissue.
Step 3
Biological response
CJC-1295 is a modified analog of growth hormone-releasing hormone (GHRH) with a Drug Affinity Complex (DAC) conjugation at Lys30. The DAC binds to albumin in circulation, dramatically extending the half-life. This allows sustained pulsatile GH release rather than a single spike, more closely mimicking physiological GH secretion patterns.

CJC-1295 with DAC is a game changer for GH. The Teichman 2006 study showed 2-10x GH increase from a single dose, lasting up to 6 days. That extended half-life is the whole point of the DAC modification.
Started CJC-1295 DAC primarily for sleep quality. The deep sleep improvement was noticeable within the first week. GH pulses happen primarily during deep sleep, so this tracks with the mechanism.
The nice thing about CJC-1295 is it's one of the few peptides with actual human clinical trial data, not just animal studies. The Teichman paper was a proper RCT.
