MK 677 (Ibutamoren) 90–120 minutes 120–180 minutes post-dose 4–6 hours sustained Non-peptide ghrelin agonist. Creates baseline GH elevation rather than acute pulse; better for recovery than intra-workout synergy Best for daily dosing to support multi-session t

- MK 677 (Ibutamoren)
- 90–120 minutes
- 120–180 minutes post-dose
- 4–6 hours sustained
- Non-peptide ghrelin agonist. Creates baseline GH elevation rather than acute pulse; better for recovery than intra-workout synergy
- Best for daily dosing to support multi-session training blocks, not acute timing protocols
- GHRP-2
- 45–60 minutes
- 60–90 minutes post-dose
- Rapid GH pulse initiation; peaks during post-workout anabolic window when dosed pre-training
- Ideal for single-session acute synergy; requires precise timing
- CJC1295 Ipamorelin
- 60–120 minutes post-dose
- 2–3 hours sustained
- Dual agonist. Ipamorelin triggers rapid pulse, CJC-1295 sustains it through post-workout receptor upregulation window
- Best single-compound option for peptides and weight training synergy timing protocol
- CJC-1295 (no DAC)
- 90 minutes
- 3–4 hours sustained
- GHRH analogue. Slower onset but longer pulse; synergises with GHRP when co-administered
- Requires longer pre-workout lead time; best combined with GHRP for amplified pulse
- Hexarelin
- 30–45 minutes
- 45–75 minutes post-dose
- 60–90 minutes
- Most potent GHRP. Highest GH pulse magnitude but rapid desensitisation with chronic use
- Use sparingly (2–3×/week max) for high-priority training sessions; rotate with other GHRPs
