Most researchers who reach this dose are well past the initial side effect period and have adapted to the GLP-1 mechanism
Aim for 23g daily L-carnitine, distributed across meals to minimize GI upset in older athletes Combine with 150200mg caffeine pre-workout to amplify thermogenic fat loss effects Prioritize resistance training 4+ days/week during cuts to maintain muscle and improve fat oxidation efficiency Maintain high protein intake (1.82.2g/kg) to preserve muscle during aggressive deficits enhanced by L-carnitine Consider green tea extract (400mg EGCG daily) for additive thermogenic synergy in older athletes with slower metabolisms Comparison Table Price & Brands Before & After Before: 190 lbs, 16% body fat, solid training foundation, minimal cutting experience Protocol: 400 kcal deficit, 2.0g protein/kg, 2.5g L-carnitine daily, 5 days resistance training + 2 cardio After: 172 lbs, 8% body fat (18 lbs total loss, ~14 lbs fat + 4 lbs muscle), enhanced vascularity and definition Result: L-carnitine supported sustained performance and muscle retention during aggressive deficit
