Here’s the lowdown. The practice of your GP (and indeed endocrinologist) should be in line with very detailed guidelines available. When the testosterone is indicated and prescribed by your GP then you will pay privately for the script. For the majority of men who are non concession-card holders, the injections will be around the same price they were before. The price of topical therapy will however be considerably more expensive. Clearly, men who require treatment are likely to opt for private scripts for injections from their doctor which is cost-effective, or be referred for consideration of topical testosterone.
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
