Understanding Fat Loss & Metabolism

Fat loss and metabolism are areas of significant peptide research. Growth hormone plays an important role in fat metabolism, stimulating lipolysis (fat breakdown) and shifting the body toward using fat for fuel. Several peptides target these pathways, either by stimulating GH release or directly affecting fat cells. Research has been particularly active in developing peptides that can target fat metabolism without other hormonal effects.

How Peptides May Help

Peptides support fat loss through multiple mechanisms. GH secretagogues elevate growth hormone, which promotes lipolysis and fat oxidation. Some peptides like AOD-9604 are designed specifically to target the fat-metabolizing portions of GH without affecting blood sugar or growth. MOTS-c, a mitochondrial peptide, may improve metabolic function and insulin sensitivity. Tesamorelin is FDA-approved specifically for reducing visceral fat in certain populations.

Top Peptides for Fat Loss & Metabolism

Growth Hormone
95% Match

Tesamorelin is the only GHRH peptide FDA-approved for reducing visceral fat. Clinical trials demonstrated significant reductions in trunk fat accumulation.

Typical Protocol
2 mg daily subcutaneous injection

Metabolic & Fat Loss
90% Match

AOD-9604 is a fragment of HGH specifically designed to target fat metabolism without affecting blood sugar or growth. It has FDA GRAS status.

Typical Protocol
250-500 mcg daily on empty stomach

Growth Hormone
85% Match

Ipamorelin stimulates GH release which promotes fat metabolism. Its clean profile with minimal cortisol elevation makes it suitable for fat loss phases.

Typical Protocol
100-300 mcg, 2-3 times daily

Longevity & Metabolic
80% Match

MOTS-c is a mitochondrial peptide that activates AMPK and improves metabolic function. It's been called an 'exercise mimetic' for its metabolic effects.

Typical Protocol
5-10 mg per week

Growth Hormone
75% Match

CJC-1295 provides sustained GH elevation which supports fat metabolism, particularly when combined with Ipamorelin.

Typical Protocol
100-300 mcg combined with GHRP, 1-3 times daily

Research Summary

Clinical research on Tesamorelin demonstrated 15-18% reduction in visceral adipose tissue over 26 weeks in HIV patients with lipodystrophy. AOD-9604 studies showed increased lipolysis and inhibited lipogenesis in fat cells. Growth hormone research has consistently shown improvements in body composition, with increased lean mass and decreased fat mass. MOTS-c research in animals shows improved insulin sensitivity and resistance to obesity on high-fat diets. The combination of GH secretagogues with proper diet and exercise appears to enhance fat loss compared to lifestyle changes alone.

Frequently Asked Questions

Tesamorelin has the strongest evidence for visceral (belly) fat reduction, with FDA approval for this specific indication. AOD-9604 is also researched specifically for abdominal fat.
While peptides may support fat metabolism, they work best as part of a comprehensive approach including proper nutrition and exercise. They are not magic solutions but may enhance results from lifestyle efforts.
Metabolic effects may begin within days to weeks, but visible fat loss typically requires 8-12 weeks of consistent use combined with a caloric deficit.
Some combinations like CJC-1295 with Ipamorelin are commonly used together. However, stacking multiple peptides should be approached carefully and ideally under professional guidance.
