Semaglutide

GLP-1 receptor agonist

GLP-1 receptor agonist. Slows gastric emptying, reduces appetite signaling in the hypothalamus, improves insulin sensitivity, and reduces glucagon secretion.

Dose

Start 250mcg/week

Cycle

Long-term

Timing

Once weekly SubQ injection

Benefits & Effects

  • 15–20% body weight reduction (clinical trials)
  • Appetite suppression
  • Improved blood sugar control
  • Cardiovascular risk reduction

Reconstitution & Dosing

Reconstitution

5mg vial + 2mL BAC water = 2,500mcg/mL. 10mg vial + 2mL BAC = 5,000mcg/mL.

Dose

Start 250mcg/week. Increase by 250mcg every 4 weeks based on tolerance. Typical working dose: 1,000–2,500mcg/week.

Cycle Length

Long-term. Most researchers continue until goal weight, then taper.

Timing

Once weekly SubQ injection. Rotate sites (belly, thigh, upper arm).
