I'm not looking to be a body builder, but yes looking for optimial sports performance, don't plan on using more than 300mg a week.
With travel outbound/inbound it's a requiremnt by the TGA to:
- Carry a prescription or a letter from your doctor
- Keep the product in its original packaging

Customs have the right to confiscate, and airline guidelines are that medicines (inc needles) are always stored in carry on. I've taken my TRT kit on planes and no issues at all with security, they're used to see needles for diabetics. However if randomly searched by customs you're likely to have to show a prescription.
