About Semaglutide
GLP-1 receptor agonists slow gastric emptying, increase satiety, and improve glycemic regulation. They are used clinically for type-2 diabetes and chronic weight management. Common compounds include semaglutide, tirzepatide, retatrutide, and liraglutide.
How it's used
Once-weekly subcutaneous injection (daily for liraglutide). Most providers titrate the dose upward over weeks to months to manage side effects. Inject into the abdomen, thigh, or upper arm, rotating sites each dose.
Storage
Reconstituted vials are typically refrigerated at 36–46°F (2–8°C) and used within ~28 days. Do not freeze. Discard if cloudy or discolored. Always follow the storage guidance on your specific vial label.
Watch for
- Nausea, vomiting, diarrhea, constipation — most pronounced in the first weeks of titration
- Reduced appetite (the intended effect, but watch for muscle loss without protein intake)
- Fatigue, headache, dizziness early in titration
- Rare but serious: pancreatitis, gallbladder issues, severe dehydration

Semaglutide FAQ
Answers, not hype.
Semaglutide (also marketed as Ozempic®, Wegovy®, Rybelsus®) is a peptide in the GLP-1 category. It is an FDA-approved prescription medication. The dose ranges shown on this site (0.25–2.4 mg) are summarized from the FDA-approved label.
Semaglutide most commonly ships in 3, 5, 10 mg vials. Typical reconstitution volumes are 1, 2, 3 ml of bacteriostatic water — choose the volume to land on a syringe-friendly unit count for your target dose.
Use the formula concentration = vial mg ÷ BAC water ml, then volume = dose mg ÷ concentration, then units = volume × 100 (for U-100). For example, a 3 mg vial reconstituted with 1 ml gives 3.00 mg/ml — at the typical low dose of 0.25 mg that resolves to 8.3 units. The free reconstitution calculator on this site verifies the math against your specific vial.
