GLP-1s Help You Lose Fat—but Muscle Can Take a Hit
GLP-1 medications are incredibly effective for weight loss and blood sugar control. But here’s something many people don’t realize: while GLP-1s help you drop fat, you can lose some lean muscle along the way, too.
And muscle matters. It’s what keeps your metabolism strong, supports your joints, powers your workouts, and helps you feel steady and energized. Losing muscle can make weight loss harder—not easier.
That’s where growth-hormone–supporting peptides come in.
Peptides to the Rescue: Sermorelin & Tesamorelin
Sermorelin and Tesamorelin are two well-known peptides that help your body release more of its own natural growth hormone. They don’t replace hormones—they simply remind your system how to repair, recover, and rebuild more efficiently.
Think of growth hormone as your body’s “restore mode.” It helps you:
-
Build and maintain lean muscle
-
Burn fat more effectively
-
Heal and recover after workouts
-
Boost energy, mood, and overall vitality
These peptides work with your body’s natural rhythm, offering support that feels steady—not overstimulating.
Why GLP-1 Patients Benefit So Much
Protect Your Muscle While Losing Fat
GLP-1s target fat, but without support, some muscle can slip away too. Sermorelin and Tesamorelin help preserve the lean muscle you already have—making your weight loss healthier and more sustainable.
Recover Faster and Stay Consistent
When you’re losing weight, workouts can feel harder. These peptides help your body bounce back more quickly, so movement feels easier and you stay motivated.
Feel Stronger and More Energized
Growth hormone supports more than muscle—it impacts energy, mood, sleep quality, and overall well-being. Many people say they feel more “alive” and resilient.
Better Long-Term Health
Muscle is protective. It supports your bones, keeps your metabolism healthy, and reduces injury risk. Keeping it now pays off for years.
How Sermorelin and Tesamorelin Differ
Sermorelin
A gentle, steady option that supports nightly growth hormone rhythms. Great for sleep, recovery, longevity, and foundational wellness.
Tesamorelin
A stronger, more targeted peptide known for reducing visceral abdominal fat—the deeper fat around the organs linked to metabolic and heart risks.
Both support muscle, fat metabolism, and recovery, but Tesamorelin offers the added benefit of focusing on internal belly fat.
