- The table below compares the three primary peptide approaches for growth hormone stimulation and downstream testosterone support. Categorized by mechanism, dosing complexity, and realistic timeline.
- GHRH Analogs (CJC-1295 with DAC)
- Binds GHRH receptors on pituitary somatotrophs, triggering sustained GH pulse elevation
- 2mg subcutaneous injection once weekly, preferably evening
- 50–70% increase from baseline within 4 weeks
- Free testosterone rises 15–20% by week 8–12 if testicular function is intact
- Best for users prioritizing convenience and steady GH elevation. Single weekly dose, minimal desensitization risk
- GHRPs (GHRP-2, Hexarelin)
- Activates ghrelin receptor (GHS-R1a), amplifies GH release while blocking somatostatin inhibition
- 100–300mcg subcutaneous, 2–3× daily (morning, pre-workout, bedtime)
- 60–80% increase from baseline with consistent dosing
- Modest testosterone gain (10–18%) visible by week 10–12, dependent on injection consistency
- Most potent acute GH response but requires strict dosing schedule. Ideal for stacking with GHRH analogs
- Oral GH Secretagogues (MK 677)
- Mimics ghrelin, increases basal GH secretion and pulse amplitude without injection
- 12.5–25mg oral, once daily in evening
- 50–65% increase from baseline, sustained with chronic use
- Free testosterone increases 12–18% by week 8–10, with improved sleep quality as confounding benefit
- Best entry point for peptide-naive users. Oral administration, no injection skill required, low side effect profile at ≤25mg
