Why people use CJC-1295 for growth hormone support
You're 40+, growth hormone is dropping. CJC-1295 to bring it back? The short answer: yes, this is one of the more-discussed uses for CJC-1295 - but the evidence quality and the right protocol depend on what you're actually trying to fix.
This page covers what's known, what's not, and what the editorial take is for normal humans considering CJC-1295 for growth hormone support.
What the evidence says
Evidence tier: Strong clinical. Multiple human studies support the dosing protocol; not yet FDA-labeled for this exact indication but close.
- CJC-1295 is a long-acting GHRH (growth-hormone-releasing hormone) analog - it tells your pituitary gland to make more of its own growth hormone.
- Phase 1 and 2 trials (Teichman et al., 2006) showed sustained 2-10x increases in growth hormone over a week.
- Most-prescribed peptide pair in US compounding for body composition - usually stacked with Ipamorelin.
Protocol notes
100mcg subcutaneous before bed, 5 days per week. Most often stacked with Ipamorelin in the same shot.
Always with a sports-medicine doctor, telehealth provider, or specialist sign-off. Self-experimenting on injection schedules without clinical input is the most common way people waste money and get hurt.
What to skip
- Vendors without a Certificate of Analysis (COA). Random gym-bro vendors with no third-party testing. The peptide market has a quality-control problem; the answer is COA per peptide, every time.
- Pre-mixed blends from non-pharmacy sources. Compounding pharmacies that produce pre-mixed combinations with COAs are fine. Random vendor "stack vials" are not.
- Massively over-dosed protocols. More is rarely better with peptides. Receptor saturation is real. Stick to evidence-based dosing.
