- Lean Mass Gain
- 2–4 kg (DEXA-verified)
- 2.5–5 kg (self-reported)
- Clinical data more reliable. Anecdotal figures likely include water weight and glycogen
- Body Fat Reduction
- 1–3% (DEXA-verified)
- 2–5% (visual estimate)
- Visual estimates overstate fat loss. Lighting, posing, and dehydration skew perception
- Typical Dose
- 20–25 mg daily
- 20–30 mg daily
- Clinical range is safer. Doses above 25 mg increase side effects without proportional benefit
- Training Frequency
- 3–4 sessions/week
- 5–6 sessions/week
- Higher frequency in anecdotal reports explains some of the discrepancy in results
- Diet Structure
- Controlled caloric deficit
- Variable (often unreported)
- Clinical trials use structured nutrition. Anecdotal results conflate compound effects with dietary changes
- Time to Visible Change
- 8–10 weeks
- 6–8 weeks (subjective)
- Anecdotal timelines reflect water retention and muscle fullness, not true lean tissue accrual
- MK-677's body composition effects are real but modest. The compound creates a favorable hormonal environment for recomposition, but it doesn't override poor training or inconsistent nutrition. Clinical data provides the floor; anecdotal reports represent the ceiling under optimal conditions.
