This comparison does not assign a generated winner or score.
- Conservative (Metabolic Focus)
- 10mg nightly
- Hold 10mg for 4 weeks, escalate to 12.5mg only if FBG <95mg/dL
- 200–250ng/mL
- Berberine 500mg 2x daily from day 1
- 16 weeks on, 8 weeks off
- Best for men with prediabetic markers or visceral adiposity >25%. Prioritizes insulin sensitivity preservation over maximal IGF-1 elevation
- Moderate (Balanced)
- 10mg for 2 weeks, 12.5mg for 4 weeks, 20mg if tolerated
- 225–275ng/mL
- Monitor FBG biweekly, add berberine if >100mg/dL
- 18 weeks on, 8 weeks off
- Standard protocol for metabolically healthy men 35-45 with baseline IGF-1 <200ng/mL. Balances anabolic signal with metabolic safety margin
- Aggressive (Performance)
- 12.5mg nightly
- 12.5mg for 2 weeks, escalate to 25mg by week 4
- 250–300ng/mL
- Metformin 500mg daily from day 1, FBG monitoring weekly
- 20 weeks on, 10 weeks off
- Reserved for men with confirmed insulin sensitivity (HOMA-IR <1.5) and baseline IGF-1 <180ng/mL. Highest anabolic potential but requires stricter monitoring
- Split-Dose (Advanced)
- 5mg morning, 5mg evening
- Hold split dose for 4 weeks, escalate to 7.5mg 2x daily if tolerated
- 210–260ng/mL
- Berberine with evening dose, FBG monitoring biweekly
- Reduces peak insulin spikes by spreading ghrelin receptor activation across two pulses. Useful for men with reactive hypoglycemia or early glucose intolerance
