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.
Dianabol can be used as a stand alone and be taken by itself, or it can be used with an injectable steroid such as testosterone cypionate or boldenone. It’s never recommended to take Dianabol with another 17 alpha-alkylated oral steroid. Dosage of Dianabol can range anywhere from 20-150mg per day, and its usually taken for 4-10 week durations. The lower the dose, the longer it can be taken without noticeable side-effects. Dianabol is a very potent steroid that can generate very dramatic gains at a dose ranging from 20-40mg per day. It’s not uncommon though to see people today pushing the dose well past the 100mg mark, but we need to remember that bodybuilders and powerlifters were benefiting from just 10mg of this steroid per day in the late 50’s and early 60’s. The half-life of Dianabol is roughly 5 hours, and a dosing schedule should be designed with this in mind.
Steroids were invented in 1930’s not 1929. secondly it was tested on animals not humand. thirdly it was in Europe. Steve competed in the 40’s till 1950 wich was his last competition. Steve would have had to have gone to Soviet Union to get steroids or Nazy Germany were they were being tested on soldiers. Highly doubftul since Steve was in the Navy. Steroids wer brought here in 1954 by Dr. Ziegler and started experimenting on bodybuilder in late 50’s well past Steve’s competition years. which i believe was dianabol, deca was invented in 1962. Steve was a natural body builder.
