This guide provides detailed instructions for the proper reconstitution (activation) and administration of peptides. Following these steps ensures maximum peptide effectiveness and safe application.
Required Materials
Before you begin, prepare the following:
Vial with lyophilized peptide (powder)
Bacteriostatic water for injection (can be purchased at a pharmacy without a prescription)
Mixing syringes (larger, 3-5 ml)
Insulin syringes for administration (smaller, with markings in units)
Needles (two types):
Longer needle (23-25G) for drawing and mixing
Shorter needle (27-31G) for subcutaneous administration
Alcohol wipes
Sharps disposal container
Gloves (recommended, but not mandatory)
1. Preparing the Workspace
Clean the work surface with a disinfectant.
Thoroughly wash your hands with soap and water for at least 20 seconds or use a hand sanitizer.
Prepare all necessary materials and place them on a clean surface.
Check the expiration dates on all materials.
2. Reconstitution (Activation) of the Peptide
Step 1: Preparing the Vials
Remove the plastic caps from the peptide vial and the bacteriostatic water vial.
Clean the rubber stoppers of both vials with alcohol wipes and wait 30 seconds for them to dry.
Step 2: Preparing the Mixing Syringe
Open the syringe and needle packaging, being careful not to touch the tip of the syringe or the needle.
Attach the needle to the syringe with a firm twist.
Remove the protective cap from the needle just before use.
Step 3: Drawing the Bacteriostatic Water
Draw air into the syringe in an amount equal to the amount of water you will draw (e.g., if you need 2 ml of water, draw 2 ml of air).
Insert the needle through the rubber stopper of the bacteriostatic water vial, holding the vial upright.
Inject the air into the vial to create positive pressure.
Turn the vial upside down, holding it in one hand and the syringe in the other.
Slowly draw the required amount of water into the syringe, making sure the tip of the needle is immersed in the liquid.
Check for air bubbles in the syringe and remove them by gently tapping the syringe and expelling the air.
Note on Dosing: The amount of bacteriostatic water you need to add depends on the concentration you want to achieve. It is common to add 1-2 ml of water to 5 mg of peptide. Check the specific instructions for your peptide.
Step 4: Reconstituting the Peptide
Hold the peptide vial upright on a flat surface.
Slowly inject the water into the peptide vial, directing the stream of water DOWN THE SIDE of the vial, not directly onto the powder.
Do not shake the vial as this can damage the peptide molecules.
Gently swirl or roll the vial between your palms for 3-4 minutes until the powder is completely dissolved.
Check that the solution is clear and free of visible particles. If you see particles or cloudiness, continue to gently roll the vial until it is completely dissolved.
3. Administering the Peptide
Step 1: Preparing for Injection
Remove the insulin syringe from its packaging.
Clean the rubber stopper of the reconstituted peptide vial with an alcohol wipe.
Insert the needle through the stopper and turn the vial upside down.
Slowly draw the prescribed dose of peptide into the syringe.
Remove air bubbles by gently tapping the syringe and carefully expelling the air.
Step 2: Choosing the Injection Site
For subcutaneous injection, the best sites are:
Abdomen (at least 5 cm from the navel)
Outer part of the upper arm
Front of the thigh
Upper outer quadrant of the buttock
For intramuscular injection (if prescribed):
Deltoid muscle (shoulder)
Vastus lateralis (outer part of the thigh)
Gluteus medius (middle part of the buttock)
Step 3: Preparing the Injection Site
Choose an injection site that is not damaged, red, swollen, or irritated.
Clean the injection site with an alcohol wipe in a circular motion from the center outwards.
Wait for the skin to dry completely (about 30 seconds).
Step 4: Administering the Injection
For subcutaneous injection:
Pinch the skin between your thumb and forefinger to create a fold.
Hold the syringe like a pencil at a 45-degree angle.
With a quick, firm motion, insert the needle into the skin fold.
Slowly inject the peptide by pressing the plunger.
Wait 5 seconds before withdrawing the needle to ensure all the peptide is injected.
Withdraw the needle at the same angle you inserted it.
Press the injection site with a clean cotton ball or gauze (do not rub).
For intramuscular injection (if prescribed):
Stretch the skin at the injection site.
Hold the syringe at a 90-degree angle (perpendicular to the skin).
With a quick, firm motion, insert the needle all the way into the muscle.
Pull the plunger back slightly to check that you have not hit a blood vessel (if blood appears in the syringe, withdraw the needle and try another site).
Slowly inject the peptide by pressing the plunger.
Withdraw the needle and press the injection site with a clean cotton ball or gauze.
4. After Administration
Dispose of the needle and syringe in a sharps container.
Do not reuse needles or syringes.
Store the reconstituted peptide in the refrigerator (2-8°C) unless otherwise specified.
Record the date and time of reconstitution on the vial.
Follow the dosing schedule as recommended.
5. Storing Peptides
Lyophilized (powdered) peptides can be stored at room temperature or in the refrigerator, depending on the type of peptide.
Reconstituted peptides are usually stored in the refrigerator (2-8°C).
Avoid exposure to light – store in the original packaging or wrapped in aluminum foil.
Check the expiration date of the reconstituted peptide (usually 2-4 weeks in the refrigerator).
6. Important Notes and Safety Precautions
Always use a sterile technique throughout the procedure.
Never share needles or syringes with others.
Rotate injection sites to avoid tissue damage.
Monitor for any side effects and consult a doctor if they occur.
Properly dispose of medical waste according to local regulations.
Keep all materials out of the reach of children.
7. Common Mistakes to Avoid
Shaking the peptide vial (instead, gently roll it between your palms).
Injecting water directly onto the powder (instead, direct the stream down the side of the vial).
Using plain water instead of bacteriostatic water for injection.
Exposing the peptide to high temperatures or direct sunlight.
Using the peptide after its expiration date.
