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.
Hey John, that’s a really interesting video on the effects of sleep on testosterone levels. I know that can really mess with hormone levels. The same thing happens during extreme dieting and many competitive bodybuilders have the T levels of 90 year old men pre-contest. I’ve always been diligent about getting enough sleep and a bad night for me was 7 or 8 hours. I’ve also never gone much under 2,500 calories per day. As far as overtraining, I had periods where I would get so burnt out I would take a week off and then reset my program and work back up to my previous weights over the course of a month or so. Even during these easy periods the symptoms were all there. Before going on TRT my blood pressure, lipids, and body fat levels were all really good so I don’t think metabolic syndrome was at work. Thanks for the resource!
