In Australia the only commercial grade Injectable TRT medications come in 1ml pre filled syringes (Bayer Primoteston or Sustanon). This needs to be transferred into a sterile vial so we can accurately administer smaller, more frequent doses.

Our doctors prescribe small doses generally administered 2-3 times per week, which enables patients to have more stable serum testosterone levels compared to 1 large injection every 2 weeks, and results in better treatment outcomes.

What You'll Receive:

  • 6 x 1ml Primoteston (Testosterone Enanthate) Pre-Filled Syringes or 6 x 1ml Sustanon Ampules

  • 2 x 5ml Empty Sterile Vials

Your Injection Kit:

  • 28 x 1ml Syringes

  • 28 x 25g 1” Needles (Injections)

  • 28 x 21g 1” Needles (Drawing)

  • 28 x Alcohol Swabs

  • 1 x Sharps Bin

Storage:

  • Keep in a dark cool area with no direct sunlight

  • Vials should be replaced each resupply

Preparing Your Treatment

1. Prepare Vial

  1. Take off the cap of the empty Vial

  2. Wipe the rubber top with an alcohol swab

  3. Set aside

2. Prepare Medication

  1. Open the Primoteston box

  2. Put the 3 plastic packets on a sterile table

  3. Assemble the syringes with the large needles that come in each pack, as instructed on the Primoteston box

  4. Set the three syringes aside, with the needle caps still on

  5. For patients prescribed Sustanon, snap the top off the ampule as per instructions included, assemble a 1ml needle with a 21g Drawing needle, and set aside

  6. Do not discard your medication packaging as it has your prescription details on it

3. Transfer to vial

  1. Place the vial on the table upright

  2. Remove a Primoteston needle cap, exposing the needle

  3. Insert needle into the rubber membrane of the vial

  4. Push down on plunger to transfer the oil into the vial

  5. Pull back on plunger to draw in 1ml of air (this will ensure the vial is not pressurised)

  6. Repeat steps 2-5 with the remaining two Primoteston syringes

  7. For Sustanon patients, draw 1ml into the syringe, and inject into the vial with the above instructions

4. Preparing your dose

  1. Set aside: 1 x syringe, 1 x 25g needle, 1 x 21g needle

  2. Remove the packaging of the above items

  3. Connect the 21g needle to the low dead space syringe

  4. Hold the vial in one hand, and the assembled syringe in the other hand

  5. Insert the needle into the vial

  6. Rotate the vial, so that the rubber top is facing the floor.

  7. Proceed to pull down on the plunger to the prescribed dose on the syringe

  8. Ensure there is no air in the syringe

  9. Rotate the vial, so that the rubber top is facing the sky

  10. Remove needle from vial

  11. Pull down on the plunger to pull in any oil that may be stuck in the needle, into the syringe - it is OK if you pull in some air too

  12. Remove the 21g needle

  13. Put on the 25g needle

  14. Aim the needle directly vertical and slowly remove any air

  15. Double check that your prescribed dose is on the syringe

5. Injecting your dose

NOTE: This medication is only to be injected intramuscularly, not subcutaneously.

  1. Select your injection site

  2. Wipe it with an alcohol swab

  3. Wait 10 seconds to dry

  4. Take a deep breath and relax the muscle

  5. Insert needle in a swift motion

  6. Slowly press down on plunger to inject the oil

  7. Remove needle once done

  8. Put needle into the sharps container

  9. Put syringe into your bin

For patients who travel regularly:

please do not put all of the Primoteston in the vial, as you will need to keep medication in original packaging with prescription label when going through customs. Transfer as much is needed when overseas, and do not bring back the used vial.
