Semaglutide

Full Year Protocol

5mg × 10 vials — Weight Loss

$210

$0.58/day — 12 months

What it does

Semaglutide is a GLP-1 receptor agonist that mimics the incretin hormone GLP-1. It slows gastric emptying, reduces appetite signalling in the hypothalamus, and improves insulin sensitivity. The result is reduced hunger, earlier satiety, and improved glycaemic control.

Originally developed by Novo Nordisk, semaglutide has become the most widely studied GLP-1 compound in history. Its long half-life (approximately 7 days) allows for once-weekly dosing, making it practical for extended protocol adherence.

Dosage & Protocol

Subcutaneous injection, once weekly. Titration: 0.25mg/week (weeks 1-4), 0.5mg (weeks 5-8), 1.0mg (weeks 9-12), 1.7mg (weeks 13-16), 2.4mg (week 17+). 10 vials at 5mg = 50mg total, providing a full 12-month protocol including titration.

What to expect

Week 1-2: Reduced appetite and food noise. Some mild nausea. Minimal scale change.

Week 2-4: Noticeable appetite suppression. Early weight loss (2-5 lbs). GI side effects peak then settle.

Week 4-8: Steady weight loss of 1-2 lbs/week. Food preferences shift — less desire for high-fat/sugar foods.

Week 8-16: Significant consistent weight loss. Most GI side effects resolve. Users report feeling "normal" about food.

Week 16-68: Continued progressive weight loss. Average total: 15-17% body weight by week 68 (STEP trials).

Who it's for

Researchers studying metabolic regulation and appetite control

Those transitioning from or comparing against branded Ozempic/Wegovy protocols

Anyone focused on body composition optimisation with clinical-grade compounds

Those looking for the most validated GLP-1 agonist available

Safety notes

⚠️Common side effects: Nausea (44%), diarrhea (30%), vomiting (24%), constipation (24%). Most mild-to-moderate and resolve with dose titration.

⚠️Serious but rare: Pancreatitis, gallbladder issues, potential thyroid C-cell tumor risk (rodent data, carries boxed warning).

⚠️Contraindications: Personal/family history of medullary thyroid carcinoma (MTC) or MEN2, history of pancreatitis.

⚠️Muscle loss: Significant weight loss includes lean mass. Resistance training and high protein intake (1g/lb) strongly recommended.
