Which peptide do you recommend for gaining muscle and burning only fat?
For research purposes, the most highly recommended peptides for body recomposition(simultaneously building muscle and burning fat) are those that stimulate the body’s natural production of Growth Hormone (GH).
Unlike synthetic HGH, which can shut down natural production and cause side effects like water retention, these peptides work with the body's natural "pulses" to promote lean mass and lipolysis (fat breakdown).
Here are the top-tier recommendations based on current research:

1. The "Gold Standard" Stack: CJC-1295 + Ipamorelin

This is the most popular combination for "lean gains."
  • CJC-1295 (without DAC):A GHRH (Growth Hormone Releasing Hormone) analog that increases the amplitudeof GH pulses.
  • Ipamorelin:A GHRP (Growth Hormone Releasing Peptide) that increases the numberof GH pulses while being highly selective—meaning it does notincrease hunger (ghrelin) or cortisol/prolactin levels.
  • The Result:This synergy leads to increased nitrogen retention (muscle growth) and significant fat oxidation, particularly in the abdominal area.

2. Tesamorelin (The Fat Loss Powerhouse)

Tesamorelin is widely considered the most potent peptide for fat loss, specifically visceral adiposity(the hard fat around organs).
  • Muscle Gain:It effectively raises IGF-1 levels, which is the primary driver for muscle tissue repair and growth.
  • Fat Loss:It was originally FDA-approved to treat lipodystrophy because of its unparalleled ability to shave off stubborn body fat.
  • Best for:Researchers focusing on achieving a "shredded" look while maintaining or slightly increasing lean muscle mass.

3. HGH Fragment 176-191 (Targeted Fat Burning)

If the primary goal is fat loss without affecting blood sugar or insulin sensitivity, this is the specific "lipolytic" fragment of the GH molecule.
  • How it works:It mimics the way natural GH regulates fat metabolism but without the growth-promoting effects.
  • Note:It does notbuild muscle on its own. It is almost always stacked with CJC-1295or IGF-1 LR3to provide the muscle-building component.

4. IGF-1 LR3 (Direct Muscle Hyperplasia)

While GH secretagogues (like those above) work indirectly, IGF-1 LR3 works directly on muscle tissue.
  • Muscle Gain:It promotes hyperplasia, which is the splitting of muscle cells to create newmuscle fibers, rather than just making existing ones larger (hypertrophy).
  • Fat Loss:It increases glucose transport to muscle cells rather than fat cells, effectively "starving" fat while fueling muscle.

Why Quality Matters (The Sgreats Advantage)

When researching peptides for body composition, purity is the deciding factor.
  • Low Purity = Water Retention:Impure peptides often contain residual solvents or salts that cause subcutaneous water retention, which masks fat loss and makes the muscles look "soft."
  • The Sgreats Standard:By using 99%+ pure peptidesverified by HPLC and ESI-TOF MS, researchers can ensure that the weight changes observed are due to actual tissue synthesis (muscle) and lipid mobilization (fat loss), not systemic inflammation or water weight.
