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.
Precision Gear Works offer two versions of this drug, one being Tren 150 which is dosed at 150mg/ml and contains the Enanthate ester and Tren-Ace 80 which is dosed at 80mg/ml of the Trenbolone acetate ester. Dosage on the acetate ester ranges from around 40mg every day or 80 every other day right up to 80mg every day or 160mg every other day, some users have reported dosages at 200mg ED and, while I think that is just crazy if you compare the anabolic/androgenic ratio to a powerful hormone such as testosterone you will see why. If you are using the Enanthate base you will be looking at around at around 2ml per week, which would be around 300mg of the drug. I would suggest starting off on the Ace version and seeing how your body responds to Tren, the last thing you want is a long ester at work when you start to develop some really nasty side effects.
Combined preparations . A number of trials have been carried out with implants containing two hormones. The combination of an oestrogen with an anabolic steroid, or with progesterone, has met with the greatest responses. Synovex-S has consistently increased gain as well as FCE, with responses averaging about 20% and 17% respectively (20, 21, 22, 34, 35, 36, 37, 42, 43, 44, 45, 46, 47, 48). Hexoestrol + TBA (usually 30 or 45 mg hexoestrol + 300 mg TBA) has resulted in marked increases in gain (24, 25, 26, 29, 49, 50, 51, 52, 53), of the order of 30% and in FCE (25, 49, 50, 51, 53) of the order of 20%. Oestradiol-17β + TBA (20/140 mg) has given similar results (27, 28, 37, 54, 55), as has Zeranol + TBA (36/300 mg), also recently tested (27, 37, 38, 39, 40, 41, 56).
