Looking for a GLP-1 medication comparison chart that puts every option side by side? You are in the right place. The number of GLP-1 medications has grown rapidly, and each one has different strengths. Efficacy, side effects, cost, dosing frequency, and route of administration all vary. This guide breaks down every major GLP-1 medication so you can have an informed conversation with your provider.

Key Takeaways: - Injectable GLP-1 Single Agonists - Dual and Multi-Agonist Options - Oral GLP-1 Options - Cost and Access Comparison - Learn how to choose the right glp-1 medication

Let's compare them all.

Injectable GLP-1 Single Agonists

These medications target the GLP-1 receptor only. They were the first generation of GLP-1 drugs and remain widely used today.

Semaglutide (injectable) is the most prescribed GLP-1 for weight management. Given as a weekly injection, clinical trials showed approximately 15% body weight loss at the 2.4 mg dose. It has strong cardiovascular safety data and is available as a personalized compounded medication through FormBlends. The most common side effects are nausea, vomiting, and diarrhea, which typically improve over the first few weeks.

Liraglutide requires a daily injection at the 3.0 mg dose for weight management. Clinical trials showed about 8% body weight loss. While less effective than semaglutide for weight loss, it has a long safety track record and may suit people who prefer daily dosing control. It also showed a 13% reduction in major cardiovascular events in the LEADER trial (Marso et al., NEJM, 2016).

Dulaglutide is a weekly injection primarily used for type 2 diabetes. It produces moderate weight loss of about 3-5% and is not specifically approved for weight management. It is often well-covered by insurance for diabetes.

"We now have cardiovascular outcomes data showing semaglutide reduces MACE events by 20% in people with obesity, independent of diabetes status. The SELECT trial changed how we think about these medications.") Dr. A. Michael Lincoff, MD, Cleveland Clinic, lead author of SELECT

Exenatide comes in both a twice-daily and once-weekly version. Weight loss is modest (about 3-5%), and it is primarily used for blood sugar control. It has been on the market since 2005, giving it the longest track record of any GLP-1.

Dual and Multi-Agonist Options

These medications target multiple hormone receptors, which generally produces greater weight loss.

Tirzepatide targets both GLP-1 and GIP receptors. Given as a weekly injection, it showed about 22% body weight loss in the SURMOUNT trials. It is currently the most effective FDA-approved weight management medication. Side effects are similar to other GLP-1 drugs. It is also available through compounding pharmacies. See our for details.

Retatrutide (investigational) is a triple agonist targeting GLP-1, GIP, and glucagon. Phase 2 trials showed 24% body weight loss. It is still in Phase 3 trials and not yet available.

CagriSema (investigational) combines semaglutide with cagrilintide (an amylin analog). Phase 3 data showed 22-25% weight loss. It could be one of the next drugs to reach market.

Oral GLP-1 Options

For people who prefer pills over injections, oral options are growing.

Oral semaglutide (Rybelsus) is currently available at doses up to 14 mg daily. At this dose, it produces about 5-7% weight loss. Higher doses (25-50 mg) in clinical trials showed about 15-17% weight loss and may receive approval. The tablet must be taken on an empty stomach with minimal water, followed by a 30-minute fast.

Orforglipron (investigational) is a small molecule oral GLP-1 from Eli Lilly. Phase 2 data showed about 14.7% weight loss. Unlike Rybelsus, it can be taken with food. Potential availability in late 2026 or 2027.

Cost and Access Comparison

Cost is often the deciding factor. Here is the market.

Brand-name injectable semaglutide and tirzepatide can cost $1,000 or more per month without insurance. Insurance coverage varies widely based on your plan and the indication (diabetes vs. Weight management).

Liraglutide and dulaglutide are similarly priced at brand-name levels, though some have better insurance coverage for diabetes.

Compounded semaglutide and tirzepatide through platforms like FormBlends typically cost significantly less than brand-name options. These are personalized medications prepared by licensed US-based 503A pharmacies and prescribed by licensed providers.

How to Choose the Right GLP-1 Medication

The best GLP-1 medication for you depends on several factors. Your primary goal (weight management vs. Blood sugar control vs. Both) matters. Your tolerance for injections, your budget, and your medical history all play a role.

If weight loss is your primary goal, tirzepatide or semaglutide are typically the strongest options available today. If cost matters (and it usually does), compounded versions through telehealth platforms offer the same active ingredients at lower prices.

If you have type 2 diabetes, several of these medications are approved for both conditions, which may improve insurance coverage.

Your provider is the best person to help you handle this decision. They can evaluate your health history, current medications, and goals to recommend the right fit.
