CJC-1295 Hair Growth Protocol Dosage Timing: Administration Method Comparison
Injection Timing 30–60 minutes before sleep onset Morning or midday dosing Pre-sleep timing aligns with nocturnal GH pulse, amplifying natural secretion by 2–3×; daytime dosing fights cortisol/insulin suppression Dose Frequency 2×/week (e.g., Mon/Thu) Daily mi

- Injection Timing
- 30–60 minutes before sleep onset
- Morning or midday dosing
- Pre-sleep timing aligns with nocturnal GH pulse, amplifying natural secretion by 2–3×; daytime dosing fights cortisol/insulin suppression
- Dose Frequency
- 2×/week (e.g., Mon/Thu)
- Daily microdosing or 1×/week
- Twice-weekly maintains IGF-1 above follicle stimulation threshold (250 ng/mL); daily dosing with DAC version causes receptor desensitisation
- Injection Site
- Subcutaneous abdominal tissue
- Intramuscular deltoid or quad
- Subcutaneous absorption is slower and more consistent. IM injection causes faster peak/faster clearance, destabilising IGF-1 curve
- Evening Carbohydrate Intake
- <30g within 3 hours of dose
- >75g carbs at dinner
- High insulin blunts GH release by 40–60%. Protein-focused evening meals preserve peptide efficacy
- Reconstitution Volume
- 2mL BAC water per 2mg vial
- 1mL or 3mL dilution
- 1mg/mL concentration allows precise 0.2–0.3mL dosing; over- or under-dilution increases measurement error risk
