What Are the Best Peptides for Weight Loss?
This guide ranks the top research peptides for weight loss based on current evidence, safety profiles, and practical considerations.
Each compound below has been evaluated on its mechanism of action, research depth, ease of use, and availability from quality sources.
#1: Retatrutide — Retatrutide (LY3437943)
Retatrutide is a Triple hormone receptor agonist researched for substantial weight loss (up to 24.2%), improved glycemic control, improved liver steatosis, reduced diabetic kidney disease markers.
Mechanism: Activates GIP, GLP-1, and glucagon receptors simultaneously for synergistic metabolic effects: GLP-1R delays gastric emptying and reduces appetite, GIPR enhances glucose-dependent insulin secretion, a
Dosage: 4-12 mg weekly (maintenance after titration) once weekly via subcutaneous injection. Cycle: 48+ weeks (continuous therapy in trials).
Why it made the list: The first triple hormone agonist targeting three distinct metabolic pathways simultaneously — producing superior weight loss compared to both semaglutide (single) and tirzepatide (dual) agonists. Read the full Retatrutide guide →
#2: Semaglutide — Semaglutide (GLP-1 receptor agonist)
Semaglutide is a GLP-1 receptor agonist incretin mimetic researched for weight loss (16-22.5%), glycemic control, cardiovascular event reduction, appetite suppression.
Mechanism: Activates GLP-1 receptors on pancreatic beta cells to enhance glucose-dependent insulin secretion and inhibit glucagon release. Crosses the blood-brain barrier to activate hypothalamic GLP-1 receptors
Dosage: 0.25-2.4 mg weekly (injection) or 3-14 mg daily (oral) once weekly (injection) or daily (oral) via subcutaneous injection or oral. Cycle: ongoing, titrated over 4-5 weeks.
Why it made the list: Only GLP-1 agonist with both injectable and oral formulations, approved across three distinct indications (diabetes, obesity, kidney disease) — the most versatile weight loss peptide on the market. Read the full Semaglutide guide →
#3: Setmelanotide — Setmelanotide (MC4R agonist)
Setmelanotide is a Melanocortin-4 receptor agonist researched for weight loss in genetic obesity, appetite reduction, energy expenditure increase, BMI reduction.
Mechanism: Directly activates melanocortin-4 receptors (MC4R) in the hypothalamic paraventricular nucleus, bypassing upstream leptin-POMC pathway defects. MC4R activation suppresses hunger signaling through AgRP
Dosage: 1-3 mg daily once daily via subcutaneous injection. Cycle: ongoing continuous therapy.
Why it made the list: The only FDA-approved treatment specifically targeting genetic forms of obesity via MC4R agonism — addresses the root cause of hypothalamic obesity rather than symptomatic appetite suppression. Read the full Setmelanotide guide →
#4: Tirzepatide — Tirzepatide (GIP/GLP-1 dual receptor agonist)
Tirzepatide is a Dual GIP/GLP-1 receptor agonist researched for superior weight loss vs GLP-1 monotherapy, glycemic control, cardiovascular improvement, sleep apnea improvement.
Mechanism: Binds GIP receptors with native GIP affinity and GLP-1 receptors with ~5:1 weaker affinity. Dual activation amplifies insulin secretion and glucagon suppression while synergistically inhibiting appeti
Dosage: 5-15 mg weekly once weekly via subcutaneous injection. Cycle: ongoing with titration over 16 weeks.
Why it made the list: First dual GIP/GLP-1 agonist to demonstrate weight loss superiority over semaglutide in head-to-head trials — single peptide addressing both insulin physiology and appetite through two complementary incretin mechanisms. Read the full Tirzepatide guide →
Can You Combine Multiple Weight Loss Peptides?
Stacking complementary peptides for weight loss is a common research approach. The key is combining compounds with different mechanisms to target multiple pathways without overlapping side effects.
See our stacking and cycling guide for principles on combining peptides safely.
How to Get Started
For beginners, start with a single, well-researched peptide rather than a complex stack. Use our dosing calculator for reconstitution math and our beginner's guide for step-by-step instructions.
Source from vendors with third-party COA testing — quality is the most important factor in achieving consistent research results.
Research-Grade Sourcing
If you're going to research Multiple, source matters. These are the suppliers WolveStack has vetted for purity and third-party testing.
