Semaglutide GLP-1 Peptide
Semaglutide is a once-weekly GLP-1 peptide used for appetite control and weight loss. It helps reduce hunger, makes it easier to stay in a calorie deficit and is especially useful during a cutting or fat-loss phase.
Thai Anabolics currently offers 5mg and 10mg vials. Both are supplied as powder and must be mixed with sterile water before use. Sterile water is included free with Thailand orders.

5mg vial
A-Tech Laboratories
A good option for customers starting Semaglutide or using lower weekly doses.

10mg vial

Weekly dosage
Semaglutide Dosage
Start low and increase slowly. Semaglutide is injected once per week. There is no reason to rush to a higher dose if appetite control and weight loss are already good at a lower dose.
| Weeks | Weekly Dose |
|---|---|
| Weeks 1–4 | 0.25mg once weekly |
| Weeks 5–8 | 0.5mg once weekly |
| Weeks 9–12 | 1.0mg once weekly |
| Weeks 13–16 | 1.7mg once weekly |
| Week 17+ | Up to 2.4mg once weekly |
The standard Wegovy injection schedule also increases Semaglutide in 4-week steps, beginning at 0.25mg once weekly.[1]
Mixing guide
How to Mix Semaglutide
For simple dosing, we recommend mixing the vials so both strengths give the same final concentration:
| Vial | Add Sterile Water | Final Concentration |
|---|---|---|
| 5mg vial | 1ml | 5mg/ml |
| 10mg vial | 2ml | 5mg/ml |
Using a U-100 insulin syringe: 100 units = 1ml. At a concentration of 5mg/ml, both vial strengths use the same syringe measurements.
| Semaglutide Dose | U-100 Syringe |
|---|---|
| 0.25mg | 5 units |
| 0.5mg | 10 units |
| 1.0mg | 20 units |
| 1.7mg | 34 units |
| 2.4mg | 48 units |
If you prefer a different amount of sterile water, use our Peptide Calculator → to calculate the correct syringe amount.
Appetite control
How Semaglutide Helps With Weight Loss
Semaglutide activates the GLP-1 receptor, helping reduce hunger and food intake. For most clients, the biggest practical benefit is simply that staying in a calorie deficit becomes much easier.
This makes Semaglutide particularly useful during a cutting phase when controlling appetite is normally the hardest part.
Clinical results
How Much Weight Can Semaglutide Help You Lose?
In the STEP 1 trial, adults using 2.4mg Semaglutide once weekly together with diet and lifestyle changes lost an average of 14.9% of their starting bodyweight over 68 weeks.[2]
Results vary, but the study shows why Semaglutide has become one of the most widely used GLP-1 treatments for weight loss.
Cutting & bodybuilding
Using Semaglutide During a Cutting Phase
Semaglutide is popular with bodybuilders and fitness clients because it can make dieting much easier. When hunger is lower, it is easier to control calories and stay consistent with the diet for several weeks or months.
Semaglutide can also be used during a cutting phase alongside anabolic steroids, HGH, SARMs, peptides and normal sports supplements. The Semaglutide dose is still based on appetite control and weight-loss response rather than the amount of other performance products being used.
When you are happy with the rate of weight loss, stay at that dose. A higher dose is not automatically better.
