Semaglutide (5mg) Dosage Guide

clear, step-by-step roadmap for safely navigating this powerful appetite-regulating and weight-support peptide.

Your weekly GLP-1 guide for appetite control and metabolic support.

Reconstitution (Mixing Your Vial)

  • Add 2.0 mL bacteriostatic water → final concentration ~2.5 mg/mL

  • On a U-100 insulin syringe: 1 unit ≈ 25 mcg

  • Use within 28 days, store in the refrigerator (2–8 °C)

  • Powder vial stores frozen at –20 °C


Weekly Dosing Schedule (Gradual Titration)

Inject once weekly on the same day each week. Slow escalation improves tolerability.

Reconstitution Steps

  1. Draw 2.0 mL bacteriostatic water.

  2. Inject slowly down the vial wall.

  3. Swirl gently (do not shake).

  4. Label your vial with the date.

  5. Refrigerate at 2–8 °C and use within 28 days.

Protocol Overview

A structured once-weekly GLP-1 regimen designed to:

  • Reduce appetite

  • Support weight management

  • Improve metabolic parameters

  • Minimize side effects through gradual titration


Storage Instructions

Lyophilized powder:

  • Store at –20 °C

  • Short-term refrigeration (2–8 °C) is acceptable

  • Protect from light and moisture

Reconstituted solution:

  • Refrigerate at 2–8 °C

  • Do not freeze

  • Use within 28 days

  • Allow vial to reach room temperature before opening to reduce condensation


Practical Notes

  • Use a new sterile insulin syringe for each injection.

  • Rotate injection sites (abdomen, thigh, upper arm) to prevent irritation.

  • Inject slowly and wait several seconds before withdrawing the needle.

  • If you miss a dose, take it within 5 days if possible.

  • Gastrointestinal symptoms early on are common; titration helps reduce them.


How It Works

Semaglutide is a GLP-1 receptor agonist that:

  • Reduces appetite and cravings

  • Slows gastric emptying

  • Improves glucose control

  • Supports meaningful weight loss (10–15% average in clinical trials)

Its long half-life (~7 days) allows convenient once-weekly dosing.


Potential Benefits

  • Significant weight reduction

  • Improved glycemic control

  • Appetite reduction

  • Cardiovascular benefits in long-term studies

  • Once-weekly convenience


Potential Side Effects

Common and usually mild:

  • Nausea

  • Vomiting

  • Diarrhea or constipation

  • Injection site irritation

Less common but more serious:

  • Pancreatitis

  • Gallbladder issues

  • Kidney concerns

  • Thyroid tumors observed in rodents (uncertain human relevance)


Lifestyle Support for Best Results

  • Prioritize adequate protein (1.2–1.6 g/kg).

  • Include resistance training 2–3 times weekly.

  • Add 150+ minutes of weekly cardio.

  • Maintain hydration.

  • Sleep 7–9 hours per night.

  • Track progress and consider guidance from a dietitian.


Injection Technique (Subcutaneous)

  • Clean vial stopper and skin with separate swabs.

  • Pinch skin; insert needle at 45–90 degrees.

  • Do not aspirate.

  • Inject slowly; wait 6 seconds before withdrawing.

  • Dispose of needles in a sharps container.
