Each peptide comes with bacteriostatic water.
Semaglutide is a synthetic peptide composed of 31 amino acids. It is a selective GLP-1 (glucagon-like peptide-1) receptor agonist, making it part of the incretin analogue group. The molecule has been modified to have an extended half-life, allowing for once-weekly administration.
Initially, it was developed and studied in the context of type 2 diabetes and obesity. Clinical trials observed an effect on weight reduction, blood sugar control, and improvement of cardio-metabolic parameters.
Semaglutide is being studied for its possible effects on:
Blood sugar control – a reduction in HbA1c and glucose peaks has been observed in research settings.
Weight reduction – an effect on body fat loss and improvement in body composition has been described.
Metabolic health – an effect on lipid profile and hepatic steatosis has been observed.
Cardiovascular function – a reduction in blood pressure and atherogenic markers has been observed in research models.
Energy homeostasis – an effect on appetite reduction and delayed gastric emptying has been described.
Semaglutide has been studied in numerous clinical trials.
In patients with type 2 diabetes, the following were reported:
- Reduction in HbA1c by up to 1.8%
- Weight loss of 6-10%
- Improvement in lipid profile and blood pressure
In people with obesity without diabetes, the following were observed:
- Average weight loss of 12-15% over 68 weeks
- Reduction in visceral fat
- Improvement in cardio-metabolic parameters
Subcutaneous administration once weekly is described in the scientific literature.
Standard doses: start with 0.25 mg weekly, then gradually titrate to 0.5 mg, 1 mg, and a maximum of 2.4 mg weekly.
For 2 mg + 2 ml bacteriostatic water: 1 mg/ml → 1 ml = 1 mg
For 5 mg + 2 ml bacteriostatic water: 2.5 mg/ml → 0.4 ml = 1 mg
For 10 mg + 2 ml bacteriostatic water: 5 mg/ml → 0.2 ml = 1 mg
Example values for 2 mg:
0.25 ml = 0.25 mg
0.5 ml = 0.5 mg
0.75 ml = 0.75 mg
1 ml = 1 mg
1.25 ml = 1.25 mg
Example values for 5 mg:
0.1 ml = 0.25 mg
0.2 ml = 0.5 mg
0.3 ml = 0.75 mg
0.4 ml = 1 mg
0.5 ml = 1.25 mg
Example values for 10 mg:
0.1 ml = 0.5 mg
0.2 ml = 1 mg
0.3 ml = 1.5 mg
0.4 ml = 2 mg
0.5 ml = 2.5 mg
The most commonly reported reactions are related to the gastrointestinal tract.
Possible side effects are highly dose-dependent and include:
- nausea, vomiting, diarrhea, constipation
- decreased appetite
- abdominal discomfort
Rarer but more serious risks include:
- pancreatitis
- gallstone disease with rapid weight reduction
- hypoglycemia when combined with other antidiabetic agents
