AOD-9604
Targeted Fat Loss
AOD-9604 shines when you want to target stubborn fat deposits. It works by mimicking how growth hormone breaks down fat, but without the side effects of actual HGH. Think of it as a smart missile that targets fat cells specifically.
Body Recomposition
Perfect for those who want to lose fat while maintaining muscle. Unlike many fat loss compounds, AOD-9604 doesn't affect muscle tissue or mess with your blood sugar levels—it's laser-focused on fat metabolism.
Metabolic Enhancement
Ideal for boosting your metabolism naturally. AOD-9604 increases fat oxidation (your body's ability to burn fat for fuel) without the jittery stimulant effects of caffeine or other thermogenics.
Joint Health Support
Emerging research shows AOD-9604 may help repair cartilage and support joint health. Studies in osteoarthritis models show it can reduce cartilage damage, making it a dual-purpose peptide for active individuals.
Metabolically Safe Fat Loss
Unlike many weight loss compounds, AOD-9604 doesn't raise blood sugar, doesn't affect insulin, and doesn't stimulate cell growth. It's one of the gentlest approaches to enhancing fat metabolism available.
Retatrutide
Significant Obesity Management
If you need to lose a substantial amount of weight, retatrutide is showing unprecedented results. Phase 2 trials demonstrated average weight loss of 24% at the highest dose—that's nearly 60 pounds for someone weighing 250 lbs. No other medication has matched this.
Type 2 Diabetes with Obesity
Retatrutide tackles both problems at once. It dramatically improves blood sugar control (HbA1c reductions of up to 2%) while delivering major weight loss. The dual benefit makes it especially valuable for diabetics struggling with weight.
Metabolic Syndrome Warriors
If you're dealing with the cluster of issues that includes high blood sugar, excess belly fat, abnormal cholesterol, and high blood pressure, retatrutide's triple mechanism attacks multiple aspects of metabolic dysfunction simultaneously.
Fatty Liver Disease (MASLD)
Early research shows retatrutide may significantly reduce liver fat. For people with non-alcoholic fatty liver disease, this peptide offers hope through weight loss plus direct metabolic improvements that benefit liver health.

Safety Overview
AOD-9604 has been studied in multiple human clinical trials involving thousands of participants. The safety profile is notably clean—it doesn't affect blood sugar, insulin levels, or cause the typical side effects of growth hormone. Phase 2 trials showed it was well-tolerated even at doses higher than typically used. The most common side effects are mild and injection-site related.
Contraindications
- xPregnancy or breastfeeding
- xActive cancer or history of cancer
- xKnown allergy to growth hormone-derived peptides
- xChildren and adolescents
Retatrutide
Evidence Level
Moderate human trials (Phase 1-2)
FDA Status
Research compound
Safety Overview
Retatrutide has shown a generally favorable safety profile in Phase 1 and Phase 2 clinical trials involving over 600 participants. Most side effects are gastrointestinal and tend to improve over time. The medication appears well-tolerated when doses are increased gradually. No major safety signals have emerged, but larger Phase 3 trials are still ongoing.
Contraindications
- xPersonal or family history of medullary thyroid carcinoma (MTC)
- xMultiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- xPregnancy or planning to become pregnant
- xHistory of severe pancreatitis
- xKnown allergy to GLP-1 receptor agonists
