Semaglutide dosage for weight loss typically starts at 0.25 mg once weekly and increases gradually to a maintenance dose of 2.4 mg weekly. This guide explains the exact titration schedule, how to use semaglutide safely, and what to expect when using it for weight loss in Canada.
What Is Semaglutide and How Does It Work for Weight Loss?
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist. It mimics the GLP-1 hormone, which regulates appetite and food intake. By activating GLP-1 receptors in the brain, semaglutide reduces hunger and increases feelings of fullness. It also slows gastric emptying, so food stays in your stomach longer. These effects lead to lower calorie intake and significant weight loss. In Canada, semaglutide is approved under the brand name Wegovy for chronic weight management, while Ozempic is approved for type 2 diabetes but often used off-label for weight loss.
Semaglutide Dosage Schedule for Weight Loss
The standard semaglutide dosage for weight loss follows a stepwise titration to minimize gastrointestinal side effects. You inject it subcutaneously once weekly, on the same day each week, at any time of day, with or without food. The typical schedule is:
- Weeks 1-4: 0.25 mg once weekly (starting dose)
- Weeks 5-8: 0.5 mg once weekly
- Weeks 9-12: 1.0 mg once weekly
- Weeks 13-16: 1.7 mg once weekly
- Week 17 onward: 2.4 mg once weekly (maintenance dose)
Some patients may stay at a lower dose if they achieve sufficient weight loss or have tolerability issues. Always follow your healthcare provider's guidance. In Canada, Wegovy pens deliver these exact doses, making it easy to adjust.
How to Inject Semaglutide Properly
Semaglutide comes in a pre-filled pen. Rotate injection sites among the abdomen, thigh, or upper arm. Clean the skin with alcohol, attach a new needle, and inject at a 90-degree angle. Do not inject into a vein or muscle. After pressing the button, hold the pen in place for 6-10 seconds to ensure the full dose is delivered. Dispose of the needle safely. If you miss a dose and it has been less than 5 days, take it as soon as possible. If more than 5 days have passed, skip the missed dose and take the next one on your regular day.
Expected Weight Loss Results with Semaglutide
In clinical trials, adults using semaglutide 2.4 mg weekly lost an average of 15% of their body weight over 68 weeks, compared to 2.4% with placebo. Results vary, but many people see noticeable weight loss within the first few months. For best results, combine semaglutide with a reduced-calorie diet and increased physical activity. Some users in Canada report losing 5-10% of their body weight by the 3-month mark. Consistency with weekly injections and lifestyle changes is key.
Managing Side Effects During Dose Escalation
The most common side effects are nausea, vomiting, diarrhea, constipation, and abdominal pain. These are usually mild to moderate and occur more often during dose increases. To reduce nausea, eat smaller meals, avoid high-fat foods, and stay hydrated. If side effects are severe, your doctor may slow the titration or keep you at a lower dose. Rare but serious risks include pancreatitis, gallbladder disease, and thyroid C-cell tumors. Seek medical attention for severe abdominal pain or a lump in the neck.

Semaglutide vs. Other Weight Loss Peptides
Semaglutide is often compared to other GLP-1 agonists like tirzepatide and retatrutide. Tirzepatide targets both GLP-1 and GIP receptors, leading to even greater weight loss in some studies. Retatrutide adds a glucagon receptor agonist, showing promise in trials. However, semaglutide has the longest track record and is widely available in Canada. Unlike peptides such as AOD-9604 or HGH Fragment 176-191, which target fat metabolism directly, semaglutide primarily works through appetite suppression. Your choice depends on your health profile and goals.
Where to Get Semaglutide in Canada
Semaglutide is a prescription medication in Canada. You can obtain it through a licensed healthcare provider and fill the prescription at a pharmacy. Wegovy and Ozempic are both available, but coverage varies by provincial drug plans and private insurance. Some online clinics offer telehealth consultations and mail-order delivery. Be cautious of unregulated sources, as counterfeit products exist. For research purposes, semaglutide may be sold as a peptide for laboratory use only, but human consumption requires a prescription.

Semaglutide Reconstitution and Storage
If you have semaglutide in lyophilized powder form for research, reconstitution is necessary. Typically, you add bacteriostatic water to the vial. For a 5 mg vial, adding 2 mL of diluent yields a concentration of 2.5 mg/mL. Gently swirl to dissolve; do not shake. Store reconstituted semaglutide in the refrigerator at 2-8°C and use within 30 days. Never use if the solution is cloudy or contains particles. For human use, pre-filled pens are already in solution and should be stored in the refrigerator until first use, then can be kept at room temperature for up to 28 days.
Combining Semaglutide with Other Peptides
Some individuals stack semaglutide with other peptides for enhanced results. For example, combining it with CJC-1295 and Ipamorelin may support muscle preservation during weight loss. However, this combination should only be done under medical supervision, as it can increase side effects. For anti-aging protocols, you can read about CJC-1295 Ipamorelin dosage in Quebec. Always consult a healthcare professional before stacking peptides.
Long-Term Use and Maintenance
Semaglutide is intended for long-term weight management. Stopping the medication often leads to weight regain, as the underlying appetite regulation reverts. Studies show that after discontinuation, most people regain a significant portion of lost weight within a year. Therefore, maintenance therapy at 2.4 mg weekly is common. Your doctor may adjust the dose based on your weight and tolerability. Regular follow-ups are essential to monitor progress and side effects.
Cost and Insurance Coverage in Canada
The cost of semaglutide in Canada varies. Without insurance, Wegovy can cost around $400-$500 per month, while Ozempic is slightly less. Many private insurance plans cover semaglutide for weight loss if certain criteria are met, such as a BMI over 30 or over 27 with comorbidities. Provincial drug plans may cover Ozempic for diabetes but not always for weight loss. Check with your insurer and explore patient assistance programs from the manufacturer.
Diet and Lifestyle While on Semaglutide
Semaglutide works best with a healthy diet and exercise. Focus on nutrient-dense foods like lean proteins, vegetables, and whole grains. Avoid sugary drinks and high-fat meals that can worsen nausea. Aim for at least 150 minutes of moderate exercise per week. Strength training helps preserve muscle mass during weight loss. Staying hydrated is crucial, as semaglutide can cause dehydration due to reduced thirst and gastrointestinal losses.
Who Should Not Take Semaglutide?
Semaglutide is not for everyone. Contraindications include a personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2, or hypersensitivity to the drug. It is not recommended during pregnancy or breastfeeding. Use caution if you have a history of pancreatitis, gallbladder disease, or severe gastrointestinal disease. Always disclose your full medical history to your doctor before starting.
Frequently Asked Questions About Semaglutide Dosage
Many people ask how quickly semaglutide works. Appetite suppression often begins within days, but significant weight loss takes weeks to months. Another common question is whether you can adjust the dose yourself. Never change your dose without consulting your doctor. The titration schedule is designed to balance efficacy and tolerability. If you experience plateau, your doctor may recommend staying at the current dose longer or adjusting lifestyle factors.
Monitoring Your Progress
Track your weight weekly, but focus on trends over time rather than daily fluctuations. Take body measurements and note how your clothes fit. Some people also monitor blood sugar and blood pressure, as semaglutide can improve these parameters. Report any unusual symptoms to your healthcare provider promptly.

Conclusion
Semaglutide dosage for weight loss follows a clear weekly titration from 0.25 mg to 2.4 mg. When used correctly, it can lead to substantial and sustained weight loss. In Canada, access requires a prescription, and costs may be offset by insurance. Always combine the medication with healthy habits and medical supervision for the best outcome.
