- Reconstitution Solvent
- Distilled water or saline
- Bacteriostatic water (0.9% benzyl alcohol)
- Prevents bacterial contamination during multi-dose use over 28-day stability window
- Non-negotiable for multi-subject studies
- Working Concentration
- Variable (0.5–5 mg/mL)
- 2 mg/mL standardized
- Balances injection volume accuracy with peptide stability. Higher concentrations increase aggregation risk
- Use 2 mg/mL unless volume constraints require adjustment
- Pre-Treatment Timing
- 15–60 minutes before ischemia
- 30 minutes ± 5 minutes
- Aligns with Hexarelin Tmax and allows full GHS-R1a activation before injury
- Strict timing reduces inter-subject variance by 40%
- Dosing Range
- 50–300 mcg/kg
- 150 mcg/kg for rodent models
- Peak cardioprotection at 150 mcg/kg; higher doses cause receptor desensitization without added benefit
- 100–200 mcg/kg is the therapeutic window
- Biomarker Sampling
- Single 24-hour sample
- 6-hour and 24-hour dual sampling
- Captures both acute injury peak and sustained protection. Single timepoint misses early release kinetics
- Dual sampling is essential for mechanistic clarity
