Best Peptides for Weight Loss: What Works and What We Prescribe in El Paso

First, what "peptide" means here

A peptide is a short chain of amino acids that acts as a signal in the body. That definition is broad enough to include both the medications everyone has heard of and the compounds people are curious about. Semaglutide and tirzepatide are peptides. So are tesamorelin, sermorelin and BPC-157. What separates them for weight loss is which signal they send:

• Appetite and blood sugar peptides (GLP-1s). They act on the gut-brain axis: you feel full sooner, stay full longer, and eat less without white-knuckling it. This is where the large, consistent weight loss comes from.
• Growth-hormone axis peptides. Tesamorelin, sermorelin, and CJC-1295/ipamorelin prompt your own pituitary to release more growth hormone. That shifts how the body partitions energy — more toward muscle and repair, less toward stored fat — and improves sleep. The scale moves slowly; the mirror and the waist measurement move first.
• Fat-metabolism fragments. AOD-9604 is a piece of the growth-hormone molecule that keeps the fat-burning signal without the growth or blood-sugar effects.

Anyone who tells you a growth-hormone peptide will do what semaglutide does is selling. Anyone who tells you semaglutide alone will give you the body composition you want is skipping a step. The honest answer is usually a sequence or a stack.

The peptides, ranked by evidence for weight loss

Ranges are from published trials of the reference medications; individual results vary. Compounded peptides at Solas are prescribed by a licensed provider after labs and a consultation.

Semaglutide and tirzepatide: the peptides that move the scale

If you have 20 pounds or more to lose, this is where to start. Both are weekly injections that reduce hunger and slow stomach emptying, so a normal-sized meal keeps you full. In trials, semaglutide produced roughly 10–15% body-weight loss and tirzepatide 15–20%. Our patients typically run an 8–10 month program with slow, microdosed titration to keep side effects (mostly nausea in the first weeks) manageable.

At Solas the monthly fee includes the medication itself, pre-filled and ready to inject, a monthly visit with Celeste in clinic or by telehealth, dose adjustments, and messaging with the clinic between visits. The full breakdown is in our medical weight loss cost guide.

Tesamorelin: the belly-fat peptide

Tesamorelin is the growth-hormone peptide with real trial data behind it. It is FDA-approved (for excess abdominal fat in a specific patient group), and those trials showed a measurable reduction in visceral fat — the deep fat around the organs that drives the hard, round midsection and the metabolic risk that comes with it. It does not suppress appetite and will not produce GLP-1-level weight loss.

Who it fits: someone at or near goal weight whose waist won't budge, or a man on TRT whose labs are optimized but whose midsection isn't. We often pair it with ipamorelin for a cleaner growth-hormone pulse.

AOD-9604, CJC-1295/ipamorelin, sermorelin: body-composition support

These are the peptides most often sold as "weight-loss peptides" online, and the ones most often oversold. Used correctly, they do something valuable but narrower: they change what you lose and what you keep.

• AOD-9604 is a fragment of growth hormone that keeps the fat-mobilizing signal and drops the rest, so it does not raise blood sugar or IGF-1. Human evidence is limited and mixed. We use it as an add-on during a GLP-1 program, not as a stand-alone weight-loss plan.
• CJC-1295/ipamorelin raises your own growth-hormone output in a sustained, natural-pattern way. The consistent effects are better sleep, faster recovery, and lean-mass retention; fat loss follows over months. This is the stack we reach for when a patient on semaglutide is losing muscle along with fat.
• Sermorelin is the gentler, older version of the same idea. A good first growth-hormone peptide, especially for patients over 45. We compare the two in sermorelin vs CJC-1295/ipamorelin.

The stacks we actually use

1. Weight to lose + keep your muscle: semaglutide or tirzepatide, plus CJC-1295/ipamorelin or AOD-9604 once the GLP-1 dose is stable. The peptide is there to protect lean mass and metabolic rate during the deficit.
2. Near goal, stubborn midsection: tesamorelin, often with ipamorelin. Twelve-plus weeks, measured by waist circumference and body composition, not the scale.
3. Maintenance after a GLP-1: taper the GLP-1, keep a growth-hormone peptide running to hold body composition while eating returns to normal.
4. Men on TRT: tesamorelin or CJC/ipamorelin layered on hormone therapy for the visceral fat testosterone alone doesn't clear.

What it costs in El Paso

What to expect, and when

• Weeks 1–2: GLP-1 appetite changes. Growth-hormone peptides: deeper sleep, sometimes mild water retention or tingling that fades.
• Week 4: First measurable GLP-1 weight loss. Recovery from workouts noticeably faster on CJC/ipamorelin.
• Months 3–6: Body-composition change from growth-hormone peptides becomes visible. Tesamorelin trials measured visceral fat at 26 weeks.
• Months 8–10: Typical end of a GLP-1 program at 10–20% body weight lost, then a maintenance plan.

Who should not use weight-loss peptides

Pregnancy or breastfeeding; active cancer; a personal or family history of medullary thyroid carcinoma or MEN 2 (GLP-1s); pancreatitis or gastroparesis history (GLP-1s); uncontrolled diabetes; and any pituitary condition for the growth-hormone peptides. Baseline labs and the health history at your consultation are how we catch these. Peptides ordered online without a prescription skip all of that, and purity and dosing are unverified.
