In androgen receptor studies, oral Trenbolone enanthate and acetate shows nearly no attraction or binding to the sex hormone binding proteins. This makes it an extremely attractive choice as Oral Tren demonstrates equal affinity for and binding to all tissues regardless of the quantity and presence of these proteins. This is the reason Oral Tren is a good choice in terms of supposed binding capacity. However, there is a risk of liver toxicity in certain cases so Milk Thistle should be used with it. Furthermore, those taking Oral Tren are recommended to drink 7 to 9 glasses of water a day while using Trenbolone.
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.
