1

Reconstitution

  1. 1.Wash your hands and disinfect the work surface.
  2. 2.Take the vial out of the refrigerator; disinfect the stopper with an alcohol swab.
  3. 3.Draw up the required volume of bacteriostatic water (BAC) with a sterile syringe.
  4. 4.Inject the water slowly along the wall of the vial (never directly onto the powder).
  5. 5.Let it rest 1 to 2 min, then swirl gently (never shake).
  6. 6.The solution must be clear. Store in the refrigerator (2–8 °C).

Subcutaneous injection

  1. 1.Disinfect the relevant area (see the zones below).
  2. 2.Draw up the exact dose (the reconstitution calculator is the reference).
  3. 3.Expel air bubbles by tapping the syringe.
  4. 4.In a research protocol, the subcutaneous route consists of lifting a skin fold then inserting the needle at 45–90°.
  5. 5.Inject slowly, then withdraw the needle without massaging the area.
  6. 6.Dispose of the needle in a sharps container (never reused).

Selected zone

Abdomen

The most common and easiest zone for subcutaneous injection: supple skin, rich in fatty tissue. Inject at least 5 cm away from the navel.

★ Preferred zone for most peptides (GLP-1, GH, recovery).

💉 Subcutaneous route — needle 29G–31G, 4 to 8 mm, angle 45–90°.

🔁 Rotate injection sites at every injection to prevent irritation and lipodystrophy.

🧴 Disinfect the skin, inject slowly, do not massage afterwards.

Subcutaneous injection technique

  1. 1Wash your hands
  2. 2Disinfect the zone
  3. 3Pinch the skin
  4. 4Insert the needle (45–90°)
  5. 5Inject slowly
  6. 6Withdraw and release

Zones to avoid

  • Less than 5 cm from the navel
  • Bones, joints and visible veins
  • Irritated, injured or bruised areas
  • Scars, tattoos or moles
  • Intramuscular injection — stay strictly subcutaneous

Titration protocol

  • Start low: the starting dose is used to assess tolerance.
  • Progress slowly: only increase after a stable step (often 2 to 4 weeks).
  • Listen to the signals: if effects are marked, maintain or reduce rather than increase.
  • Adjust based on data (weight, feel, effects), not on a whim.
  • Consistency matters more than intensity: small consistent steps > big jumps.

Each peptide has its own titration scheme: see its sheet and the protocol generator.

Choosing syringes & needles

  • U-100 insulin syringe (1 ml = 100 IU): the reference, precise and graduated.
  • U-50 (0.5 ml) / U-30 (0.3 ml): for small volumes, finer reading.
  • Needle: 29G to 31G, 4 to 8 mm long (suited to subcutaneous injection).
  • 1 IU = 0.01 ml on a U-100 syringe.
  • Always a new, sterile needle/syringe for each injection.
