Controlled substance. Description: Methandrolone (17α-Methylandrostan-17β-ol-3-one), also known as mesterolone, methyldihydrotestosterone, androstanolone, is used to treat male hypogonadism and spermatozoa infertility. Methyldihydrotestosterone (methyl-DHT; 17α-methyl-17β-hydroxy-5α-androstane-3- on, meandrolone) is a steroid with similar characteristics to DHT (dihydrotestosterone), but Unlike DHT, it is orally bioavailable. Methyldihydrotestosterone has been the second most commonly used steroid by athletes for the past several decades, and they topped the list in the world, largely due to the steroid's widespread use. There is relatively little information on methyldihydrotestosterone, although information on dihydrotestosterone is plentiful. This article will discuss information on methyl-dihydrotestosterone and what to expect from this compound. Meandrolone is used as an androgenic and anabolic hormone for bodybuilding muscle supplements. Mandrolone is useful during the cutting phase or when a person wishes to avoid excessive weight gain, and mestanovone is used in men with hypogonadism and to reduce sperm infertility. application: A. Meandrolone is the 17α-methylated version of dihydrotestosterone (DHT). It is an orally bioavailable androgenic steroid that is highly androgenic while being only slightly anabolic. It cannot aromatize and is not an agonist of the progesterone receptor. B. Women should avoid the use of minandrolone, because it has a strong androgen. Long-term use should be avoided for more than 12 weeks. Since minandrolone is not converted to estrogen, it is useful during the weight loss phase or when one wishes to avoid excessive weight gain. C. minandrolone cannot be converted to estrogen, but it binds strongly to SHBG, which can replace estrogen into the circulation, possibly causing estrogenic side effects. D.

Regardless of the Testosterone Enanthate doses in question, performance orTestosterone Replacement Therapy (TRT) related, we will find the compound is very well- tolerated. The higher the dose goes the greater the risk, but most men can tolerate Testosterone Enanthate doses above standard TRT levels. With that in mind, let's look at various Testosterone Enanthate doses and see if we can find the right one for you. Medical Testosterone Enanthate Dosage In the medical field, Testosterone Enanthate is primarily utilized for the treatment of androgen deficiency in adult males (hypogonadism or andropause). Testosterone Enanthate dosages for such a condition as determined by prescription guidelines are that of 50 - 400mg administered every 2 - 4 weeks. Proper Administration and Timing of Testosterone Enanthate Dosages Testosterone Enanthate possesses a half-life of 10 days due to the longer Enanthate ester. Testosterone Enanthate doses only require two injections administered every week and spaced evenly apart from one another so as to ensure stable blood levels. For example, if an individual's intention is to administer 300mg weekly of Testosterone Enanthate, it is advised to inject 150mg on Monday followed by the other 150 on Thursday. Although one may be able to 'make-do' with single weekly injections, this is not recommended due to unstable blood levels producing a greater incidence of side effects and less than desirable effects on progress and gains. Testosterone Enanthate Application: A. Testosterone Enanthate is imperative and effective for enhancing males specific sexual traits. It is the principle male sex hormone and an anabolic steroid. Testosterone Enanthate plays a key role in the development of male reproductive tissue such as the testis and prostates. B.

This is caused by a skeleton in a stable five-membered ring structure and a high silica to alumina ratio. For example, the sample calcined at 850 ℃ After 2 hours, the crystal structure unchanged. Even can withstand high temperature of 1100 ℃. So far, ZSM-5 zeolites are known to one of the highest qualitative hot temperature. Therefore, it is used in high-temperature process is particularly suitable. For example, use it as a hydrocarbon cracking catalyst, regeneration of the catalyst can withstand passage of time. Acid resistance ZSM-5 zeolite has good acid resistance, it is resistant to various acids except hydrofluoric acid. Steam stability Wang, IKai other studies have shown that when other zeolites by steam and hot water, and their general structure is destroyed, leading to irreversible deactivation. The Mobil company with ZSM-5 as the conversion of methanol (water is one of the major product) catalyst. This suggests that ZSM-5 to water vapor with good stability. 540 ℃ lower partial pressure of 22mmHg steaming column and HY zeolite HZSM-5 after 24 hours, a crystallinity of HZSM-5 and about 70 percent of fresh catalyst, but under the same conditions, HY zeolite skeleton almost completely damage. Hydrophobic ZSM-5 having a high silica to alumina ratio, the smaller the surface charge density. The water molecule is polar, so you will not ZSM-5 is adsorbed. Although water molecules smaller than the diameter of n-hexane, but the amount of adsorption of n-hexane ZSM-5 is generally greater than water. Easy to coke ZSM-5 V-shaped aperture effective, pore size and bending, preventing a large condensate formation and accumulation. Meanwhile, ZSM-5 framework is no greater than the bore of the cavity (cage) exist, so limiting the formation of large molecules from the secondary condensation reactions. So that the possibility of ZSM-5 catalyst coke is reduced. ZSM-5 for an alkyl aromatics into the tunnel barrier is formed, and thus the reaction process it can not continue to react in smaller pores, the final condensation formed coke. ZSM-5 so much slower than the rate of coke deposition and Y-type mordenite, difference of almost two orders of magnitude. Capacity of ZSM-5 zeolite carbon content is higher. Excellent shape-selective selectivity Zeolite molecular sieve as catalyst, only smaller than the hole crystal molecules can catalyze the reaction out of control pore size crystalline zeolite suffering zeolite catalyst size and shape of reactant and product molecules showed great selectivity. Pore ​​system of ZSM-5 zeolite having a 10-MR constituted medium size orifice diameter, it has a good shape-selective selectivity.
