Research-based dosing protocols, timing guidance, and reconstitution reference for Semaglutide. All information is for educational purposes only.

Quick Answer

Semaglutide is administered via subcutaneous injection or oral tablet. For weight loss (Wegovy), the dose is escalated over 16-20 weeks to a target dose of 2.4 mg once weekly. For type 2 diabetes (Ozempic), the target dose is typically 0.5-2.0 mg once weekly. Rybelsus, the oral formulation, is started at 3 mg daily, increasing to 7 mg and then 14 mg daily.

Standard Dosage Range

Research dosing range: 0.25–2.4 mg weekly (subcutaneous); 3–14 mg daily (oral)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Weight Loss (Wegovy)

0.25 mg weekly, titrating to 2.4 mg weeklyOnce weekly
Duration

Long-term (ongoing)

Dose escalation is crucial to minimize gastrointestinal side effects. Increase dose every 4 weeks as tolerated: 0.25 mg → 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg.

Type 2 Diabetes (Ozempic)

0.25 mg weekly, titrating to 0.5–2.0 mg weeklyOnce weekly
Duration

Long-term (ongoing)

Typical starting dose is 0.25 mg, increased to 0.5 mg after 4 weeks. Further dose increases to 1.0 mg or 2.0 mg may be needed for glycemic control.

Type 2 Diabetes (Rybelsus)

3 mg daily, titrating to 7 mg or 14 mg dailyOnce daily
Duration

Long-term (ongoing)

Start with 3 mg daily for 30 days, then increase to 7 mg daily. If additional glycemic control is needed, increase to 14 mg daily. Take on an empty stomach with a sip of water, at least 30 minutes before food or other oral medications.

Timing & Frequency

Semaglutide is typically administered on the same day each week (subcutaneous injection). Oral Rybelsus should be taken first thing in the morning, on an empty stomach, at least 30 minutes before eating or taking other oral medications.

Cycle Guidance

Semaglutide is typically used long-term for chronic weight management or type 2 diabetes. Discontinuation may lead to weight regain or worsening glycemic control. Consult a physician before stopping treatment.
