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.
Trenbolone Hexahydrobenzylcarbonate represents the dominant large ester based Trenbolone compound on the market. It was first released by the France based Negma Laboratories in the late 1960’s under the trade name Parabolan. This represents the first and only Trenbolone hormone to ever exist in human grade form. Parabolan was prescribed for many years in cases of malnutrition, which will make a lot of sense as we dive into the compound. It was also prescribed to treat osteoporosis in some cases, as well as in the treatment of cachexia.
Anadrol is best stored at a controlled room temperature of 20° to 25°C (68° to 77°F) with excursions permitted to 15° to 30°C (59° to 86°F). Use of Anadrol should always be made for medicinal purposes and under strict accordance with the medical recommendations. Anadrol should always be purchased with a valid medical prescription from an eminent steroid pharmacy. Dosages of this steroid should not be increased or decreased without prior medical approval. When overdosed or abused, Anadrol can lead to side effects like hepatitis and cirrhosis or hoarseness, growth of facial hair, acne, and changes in menstrual cycle. Anadrol abuse may even be a reason behind health complications like persistent or frequent erections, bladder irritability, and decrease in seminal volume, or aggravation of acne.
