Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
As for bodybuilders, Stanozolol has one interesting peculiarity demanded among them. It consists in the profound ability to lower sex hormone-binding globulin (SHBG) level resulting in efficiency growing of other steroids in stack with it. In particular, it raises the amount of biologically active free testosterone circulating in the blood. For this reason it is advisable always to use Stanozolol in stack with testosterone. Another one reason for this is as follows: Winstrol may be more prone than other anabolic steroids to increasing tendon brittleness. This happens due to Winstrol`s possibility to dry out the joint fluid, which can lead to joint pain and damages. Also both Stanozolol forms: tablets and injections have been noted to provoke adverse changes in cholesterol levels. Hence, monitoring of the lipid profile of the body (blood works) during cycle is advisable.
I was stuck on a plateau and Furostan helped me break through it. I was looking for a clean test booster. I gained about 10 lbs, and increased my bench after 1 cycle by 30lbs. Noticed aggressive pumps in the middle of sets. I would look at the heavier weights and say BRING IT. That aggression helped motivate me to lift bigger than ever before. After about two weeks noticed some size on my biceps and chest. This product will help anyone achieve their goals. Definitely will be using this product again, and recommend it to others who are looking to break plateaus.
