Testosterone esters are also being researched as a means of contraception. legal anabolic steroids How-steroids-work. 32Testosterone undecanoate is also available in an oral formulation, which is absorbed directly into the lymphatic system and thus is not immediately oxidized by the liver, as would generally be the case with a non-17-alkylated testosterone. The oral formulation has a half life of a few hours, and clinically does not result in the significant inhibition of LH/FSH that is seen with I. M. legal anabolic steroids Anabolic review. testosterone esters, perhaps because of pharmacodynamic differences. One study found no liver problems in subjects that had used the drug for 10 years or more. Testosterone undecanoate has been used successfully in treating growth problems in boys,19 and, remarkably, has been shown to improve the serum lipid profile of older men,33 and to be therapeutic to elderly male patients with myocardial ischemia, relieving angina pectoris and improving ECG and Holter recordings. legal anabolic steroids Steroid abuse. However, the clinically useful dosage is typically 240 mg/day, indicating low bioavailability of this formulation. Testosterone patches have been developed, and recently improved so that they may be applied to the skin of the back rather than of the scrotum. The makers of this product (Androderm) consider the male hormone replacement therapy market to be worth approximately $800,000,000, of which they hope to obtain 10%. Patches are also being tested for use in AIDS wasting syndrome. 34Sublingual testosterone cyclodextrin is another new product, and results in less suppression of LH/FSH than testosterone enanthate administered by I. M. injection. Half life is approximately one hour. This product is thought to be suitable for treatment of boys with delayed puberty, and for older men with androgen deficiency. 35Researchers point out that testosterone, though at a lower concentration, is also normal to the female physiology, and older women may also suffer from androgen deficiency, resulting in loss of energy, depression, impairment of sexual functioning, and headaches. Returning testosterone levels to normal female physiological values, in combination with estradiol therapy, has been found beneficial. It is felt that this is a neglected area of medical practice, and further research is needed. 36Dihydrotestosterone (Transdermal, I. M. )DHT has proven effective in the treatment of microphallus, applied topically,37 and has been shown to be of value in the treatment of elderly hypogonadal men. Within the prostate, exogenously supplied testosterone is enzymatically converted to DHT, a more potent agonist of the AR, and also to estradiol. Prostate enlargement is a common side effect of testosterone use, perhaps for these reasons. However, it has been found that when DHT itself is supplied to elderly hypogonadal men, reduction of prostate size occurs. 38 This appears to be due to inhibition of endogenous testosterone, estradiol, and aromatase. Furthermore, DHT is more potent than testosterone in most tissues (perhaps excepting muscle, as a result of enzymatic conversion to the diol) whereas testosterone is effectively less potent to those tissues lacking 5a-reductase. DHT can therefore be given in a lower dose than testosterone to achieve the same effect in target tissues, and therefore, less DHT, less testosterone, and less estradiol reach the prostate when DHT itself is given as the drug. However, DHT has not been studied much for use in replacement hormone therapy. Derivatives of DHT, such as dromostanolone, may be of interest as well. Testosterone Analogues of Value for Reasons Other Than AnabolismDanazol (Oral) "Danacrit"Danazol is the drug of choice for long term prophylaxis of hereditary angioedema.
