Protocol 1: The conservative cut (12-16 weeks) Goal: Lose 15-25 pounds of fat while preserving maximum muscle mass Best for: Bodybuilders at 15-20% body fat targeting 10-12% Retatrutide dosing: Weeks 1-4: 0.5mg weekly Weeks 5-8: 2mg weekly Weeks 9-12: 4mg weekly Weeks 13-16: 4-6mg weekly (optional increase based on response) Nutrition: Calories: 500-750 below maintenance (deficit deepens naturally as appetite suppression increases) Protein: 1.2g per pound of lean body mass minimum Carbs: 150-250g (prioritized around training) Fats: Fill remaining calories (minimum 0.3g per pound bodyweight for hormonal health) Training: 4 days per week, upper/lower split Heavy compounds at 85-95% of pre-cut working weights Reduce total sets by 20% from growth phase volume 10-15 minutes low-intensity cardio post-training or on rest days Expected results: Weeks 1-4: 2-4 pounds total weight loss, minimal visible change Weeks 5-8: 4-8 pounds fat loss, visible midsection changes Weeks 9-12: 6-10 pounds fat loss, significant visual transformation Weeks 13-16: 3-6 pounds fat loss, detail and separation emerging Total: 15-25 pounds lost, 70-80% from fat with proper nutrition and training Protocol 2: The aggressive cut (8-12 weeks) Goal: Lose 20-35 pounds of fat quickly while accepting some muscle loss risk Best for: Bodybuilders at 20-30% body fat who need significant change before a deadline Retatrutide dosing: Weeks 1-2: 0.5mg weekly Weeks 3-4: 2mg weekly Weeks 5-6: 4mg weekly Weeks 7-8: 8mg weekly Weeks 9-12: 8-12mg weekly Nutrition: Calories: 750-1,000 below maintenance Protein: 1.4g per pound of lean body mass (higher to compensate for larger deficit) Carbs: 100-200g (training days only at higher end) Fats: Minimum 0.3g per pound bodyweight Training: 3-4 days per week Heavy compounds remain priority Reduce volume by 30-40% Increase cardio to 20-30 minutes post-training if tolerated Expected results: 20-35 pounds total loss over 8-12 weeks 60-70% from fat (the larger deficit increases lean mass loss risk) Strength may decline 5-10% on key lifts Dramatic visual transformation Protocol 3: The recomposition approach (16-24 weeks) Goal: Gradually lose fat while maintaining or slightly increasing muscle mass Best for: Intermediate lifters at 18-25% body fat who are in no rush Retatrutide dosing: Weeks 1-4: 0.5mg weekly Weeks 5-8: 1-2mg weekly Weeks 9-24: 2-4mg weekly (stay at moderate dose) Nutrition: Calories: Maintenance or slight deficit (200-300 below) Protein: 1.0-1.2g per pound of lean body mass Carbs: Moderate, prioritized around training Fats: Moderate Training: 4-5 days per week Progressive overload maintained, aim for strength gains Full training volume maintained Moderate cardio 2-3 times per week Expected results: 8-15 pounds of fat loss over 16-24 weeks Potential muscle gain of 2-5 pounds (depending on training level) Net body composition improvement without dramatic scale weight change Strength maintenance or modest improvement Reconstitution and practical handling for bodybuilders Retatrutide comes as a lyophilized powder that requires reconstitution before injection
The reasons semaglutide may not produce weight loss vary from dosage issues to metabolic factors
Lifestyle Capacity Assessment Question 3: Can I realistically maintain these behaviors during off-medication periods
That discovery led researchers to begin exploring compounds that target multiple metabolic receptors simultaneously
Regular consumption of fermented foods such as yogurt, kefir, kimchi, and sauerkraut can promote this effect
Here is what the key trials showed
