Semaglutide
Fat Loss / Metabolic · GLP-1 Agonist
Semaglutide is a GLP-1 receptor agonist originally developed for type 2 diabetes that has become one of the most effective weight loss medications available. It works by mimicking a natural hormone that regulates appetite and blood sugar, helping people feel full faster and longer.

Trending Compounds
Tesamorelin
Fat Loss / Metabolic · Peptide
Tesamorelin is an FDA-approved synthetic analogue of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce natural growth hormone. It is best known for significantly reducing visceral (abdominal) fat and is the only peptide in its class with an FDA approval for HIV-associated lipodystrophy. Researchers also study it for cognitive enhancement via IGF-1 elevation and its potential to reduce liver fat.
CJC-1295
Muscle / Recovery · Peptide
A synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary to release more growth hormone. Popular in biohacker and athletic communities for recovery, muscle gain, and anti-aging effects.
Tesamorelin
Fat Loss / Metabolic · Peptide
An FDA-approved synthetic GHRH analog used medically to reduce excess belly fat (lipodystrophy) in HIV patients. Also researched for cognitive benefits and general fat loss.
TB-500
Muscle / Recovery · Peptide
A synthetic fragment of Thymosin Beta-4, a naturally occurring protein involved in wound healing, tissue repair, and inflammation reduction. Widely used in athletic recovery circles.
GHK-Cu
Skin / Glow · Peptide
A naturally occurring copper-binding peptide found in human plasma that declines with age. Widely studied for skin rejuvenation, wound healing, and anti-inflammatory effects. Available in topical skincare products.
Epitalon
Longevity · Peptide
A synthetic tetrapeptide derived from the pineal gland hormone epithalamin. Researched primarily for its purported ability to lengthen telomeres and extend lifespan — though most evidence comes from animal studies.
BPC-157
Muscle / Recovery
BPC-157 is proven to heal injuries in humans
Most evidence is from animal studies. Human clinical trials are very limited.

Common Peptide Questions
What are weight-loss peptides?
Weight-loss peptides are compounds — including GLP-1 receptor agonists like semaglutide and tirzepatide — studied for their effects on appetite, metabolism, and body weight. Some are FDA-approved for chronic weight management; others are investigational and not yet approved. Suitability should always be evaluated by a licensed healthcare provider.
Which peptide medications are FDA-approved for weight management?
As of our latest review, semaglutide (Wegovy) and tirzepatide (Zepbound) are FDA-approved for chronic weight management in eligible adults. Liraglutide (Saxenda) is also approved. Other compounds like retatrutide and cagrilintide remain investigational. Approval status changes over time — verify with the FDA database and consult a clinician.
What is the difference between semaglutide and tirzepatide?
Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GLP-1/GIP receptor agonist. Both are FDA-approved for weight management. Clinical trials suggest tirzepatide may produce greater weight loss on average, but individual results vary and head-to-head comparisons should be interpreted carefully. Your clinician can help determine which is appropriate for you.
Are research peptides safe for human use?
No. Compounds sold as 'research peptides' are not FDA-approved for human use and are not regulated for safety, purity, or efficacy. They are intended for laboratory and in-vitro research only. Using research-only compounds outside of clinical supervision carries significant health and legal risks.
What should I ask my doctor before considering a weight-loss medication?
Ask about eligibility criteria, expected benefits and timelines, common and serious side effects, contraindications, monitoring requirements, cost and insurance coverage, and whether lifestyle changes alone may be appropriate. Bring a list of your current medications and medical conditions.

Peptide Compass follows a structured editorial process. We prioritize FDA regulatory documents, ClinicalTrials.gov records, peer-reviewed clinical trials, and systematic reviews. We clearly distinguish between FDA-approved medications, investigational compounds, and research-only chemicals. We never describe unapproved compounds as proven, safe, or FDA-approved, and we never encourage self-medication.
