Why Buy Semaglutide 3mg from Peptide Scientists

Semaglutide is the most clinically studied GLP-1 agonist with years of post-approval safety data. Buying it as a research peptide gives you the same molecule found in Ozempic and Wegovy — at a fraction of pharmacy pricing.

Our Semaglutide is sourced from Phiogen with ≥98% HPLC verification. Lyophilized powder ships with full QC documentation.

The 3mg vial is the entry format — ideal for first-time buyers wanting to test tolerability before committing to larger supply. We also offer 6mg, 12mg, 20mg, and 30mg vials.

About Semaglutide 3mg

Semaglutide (CAS: 910463-68-2) is a 31-amino-acid GLP-1 analog with C18 fatty diacid lipidation, enabling once-weekly subcutaneous dosing via albumin binding.

Mechanism: GLP-1 receptor agonism in the hypothalamus drives appetite suppression; peripherally it slows gastric emptying and enhances glucose-dependent insulin secretion. The 5-day half-life supports the weekly dosing schedule used in STEP and SUSTAIN trials.

Phase 3 STEP-1 trial demonstrated −14.9% mean body weight reduction at 68 weeks (2.4mg/week dose). SELECT cardiovascular outcomes trial showed 20% reduction in MACE.

Frequently Asked Questions

Is this the same Semaglutide as Ozempic?
Yes — Semaglutide is the active pharmaceutical ingredient in Ozempic, Wegovy, and Rybelsus. We sell it as a research peptide for laboratory use. The molecule is identical.
Should I buy Semaglutide or Tirzepatide?
Tirzepatide produces greater weight loss (−22.5% vs −14.9% in trials) due to dual GLP-1/GIP agonism. Semaglutide has more years of safety data and is the cheaper entry point. Both are valid research targets.
Why is the 3mg vial so much cheaper?
It's the smallest format — the cost-effective starter for first-time Semaglutide buyers. Larger vials (12mg, 20mg, 30mg) offer better per-mg pricing for extended research protocols.
How long does the 3mg vial last?
At the STEP-1 maintenance dose of 2.4mg/week, the 3mg vial covers ~1 week. At lower starter doses (0.25-1mg/week), it covers 3-12 weeks. Standard escalation starts at 0.25mg/week.
