In the Oxford Journal of Gerontology Series A: Biological Sciences and Medical Sciences, the popular nonsteroidal SARM LGD 4033 (Ligandrol) has been recently studied for it’s effectiveness and safety in healthy young men. Results were favorable indicated by hormone and lipid levels returning to normal without the use of a post cycle therapy. No dangers were detected throughout the study. although there was noticeable suppression in testosterone and HDL cholesterol, it was not significant enough to cause adverse reactions. Because LGD 4033 is considered one of the strongest and most potent nonsteroidal SARMs available, it is not likely that less potent SARMs will produce any harmful effects (Bhasin, 2010).
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.
