Things to consider:
(1) Women already have an implant they get in their arm that steadily releases hormones.
(2) Mens' testicles shrink in response to exogenous androgens
This idea is for those of us who decide to 'stay on' and who just take a steay dose of T for the rest of our life (e.g. 350mg/wk). This idea is also for people who will blast and cruise for the rest of their life.
I think we should have our two shrunken testicles removed from our scrotum and replaced with walnut-sized implants that steadily secrete concentrated testosterone. An implant the size of a walnut containing highly concentrated T should last for a few years (365 days of 10mg daily would weigh 3.65 grams, so an implant weighing 22 grams will last 6 years).
I've done it again, I'm a fucking wizard.
