Therefore, consistent low doses are better than spiking with intermittent high doses, and advice to use 100 mg/week of testosterone propionate to avoid virilization simply makes no sense (and in practice, often fails. mexican steroid ordering Facts on anabolic steroids. )It should still be noted that some women will suffer virilization with almost any dose of anabolic steroid, regardless of dosing pattern. What are the half-lives of different esters?Shorter chain esters have shorter half-lives, because of their lower partition coefficient. Testosterone cypionate has a half-life of 8 days5, the enanthate ester has a half-life of 4 days6, and nandrolone decanoate has a half-life of 8 days7. mexican steroid ordering Lutalyse anabolic steroid use. These figures are only approximate. The difference between these values for cypionate and enanthate probably includes difference attributable to different measuring techniques. The actual difference is probably not more than two days. mexican steroid ordering Safe steroids. In the rat, where half-lives of anabolic steroid esters are similar to those in humans but somewhat shorter, the half-lives of the phenylpropionate, decanoate, and laurate esters are 1, 5, and 10 days respectively. 3 The same trend would be expected in man. Half-life is linearly related to log partition coefficient, which is itself linearly related to the carbon chain length, the exception being if the ester is an unusual one such as phenylpropionate. This was shown by James et al. 3 for the formate through valerate esters of testosterone in the rat. The half-life of testosterone propionate was approximately 4 days, and each carbon added to or subtracted from that chain length changed half-life by about 1. 5 days. How are steroid esters made, and can esters be made of prohormones?The most convenient method of synthesis of steroid esters is reaction of the steroid in a 2:1 mixture of pyridine and the anhydride of the desired ester: for example, propionic anhydride would be used to make the propionate ester. A large excess (at least 10 times) of the anhydride compared to the steroid would be required. This would then be purified by diluting with at least 10 parts of water to each part of pyridine, adding 1 part ether, decanting the water after shaking, and then washing with 10 parts water repeatedly in a separatory funnel. This would be followed preferably by recrystallization or chromatography for purification. Esters cannot be made of dione prohormones because they do not have an -OH group. Esters can be made of the diols, but purification by recrystallization probably is not possible because the product would be a mixture of 3a and 3b esters, which could be expected to yield an oily mess, or perhaps an amorphous solid. Further difficulties would include the fact that for the diols, the starting material from at least some manufacturers is of considerably less than 100% purity. I personally would not even consider injecting the product of the above reaction without some further purification besides the water wash. An even more serious consideration is that by esterifying the prohormone, one is arguably manufacturing a controlled substance. To say the least, this is a real no-no with the Drug Enforcement Agency, even moreso than possession or importing, both of which are already quite serious crimes. Therefore I cannot recommend manufacturing esters of diol prohormones, but for the sake of completeness in an article on steroid esters, I thought I would mention how they can be made and what the difficulties are. Can we make esters of Winstrol, Dianabol, etc. , for injection?While there are a number of interesting oral steroids that, at first glance, would be appealing candidates for making esters, in fact there are very good reasons why no such products are available.
