The Hierarchy of Fat Loss
There is no "Magic Pill," but there are "Magic Signals." In 2025, we categorize fat loss peptides into two distinct classes: ** Appetite Suppressors ** (GLP - 1s) and ** Metabolic Boosters ** (Secretagogues).
Class A: The Heavy Hitters(GLP - 1s)
These drugs have revolutionized medicine.They stop the "Food Noise." * ** 1. Tirzepatide(Mounjaro):** The king.By hitting both GLP - 1 and GIP receptors, it offers superior weight loss(20 % +) with theoretically fewer side effects than Semaglutide.
- ** 2. Semaglutide(Ozempic):** The standard.Tried and true.Expect ~15 % weight loss.Excellent availability.
- ** 3. Retatrutide:** (Coming Soon). The "Triple G" agonist that strips liver fat and burns more calories at rest.
Class B: The Body Re - Comps(GHS)
These don't kill your appetite. In fact, they might increase it. But they change how your body uses fuel. * ** 3. Ipamorelin:** Spares muscle while you diet.It forces the body to tap into adipose tissue for energy while preserving lean mass.Crucial for avoiding the "skinny fat" look of Ozempic.
- ** 4. Tesamorelin:** The specific "Belly Fat" destroyer.
- ** 5. AOD - 9604:** "Anti-Obesity Drug." A fragment of HGH that targets lipolysis.Results are milder but side effects are non - existent.
The Winning Strategy ?
- ** Obese(BMI > 30) :** Start with ** Semaglutide ** or ** Tirzepatide **.
- ** Athletic / Last 10 lbs:** Use ** Ipamorelin ** + ** Tesamorelin **.
- ** Maintenance:** Cycle ** AOD - 9604 ** to keep the weight off.
