Steroid hormone de croissance

It has some mild side effects associated with it as well. Side effects occur when you take it for a very long period of time and in more quantity. Major drawback of Anavar is that it is too costly, although available in black market but one cannot be so sure of the authenticity of it bought from there. As it is DHT and due to this hair loss and acne can occur. But hair loss only in men who have got this hair loss disease genetically transmitted. There could be high blood pressure and high cholesterol levels but only for those who are not living a healthy life style and these diseases are not transmitted genetically to the users as well. Due to the non aromatizing nature of Anavar it has taken side effects of water retention and Gynecomastia out of the equation.

Measurement of steroid hormones by mass spectrometry does provide distinct advantages. First due to the flexibility of the instrument multiple analytes can be measured in a single run which allows for reporting of several analytes in one sample [1] . Additionally, the use of mass spectrometry can support the large dynamic range typically seen in steroid hormones , where concentration ranges within analytes can vary significantly (., testosterone concentrations < 10 ng/dL can be observed in women and children and concentrations over 1000 ng/dL can be seen in men) [2] . Additionally, it can support differences in the concentration range between analytes; for example, testosterone in men as high as 1000 ng/dL can be measured in the same sample with an estradiol concentration as low as 10 pg/mL [1] .

Depending on the number and character of their functional groups, steroid molecules may show diverse reactivities. Moreover, the reactivity of a functional group varies according to its location within the molecule (for example, esters are formed readily by 3-OH groups but only with difficulty by the 11β-OH group). An important property of steroids is polarity —., their solubility in oxygen-containing solvents (., water and alcohols ) rather than hydrocarbon solvents (., hexane and benzene ). Hydroxyl, ketonic, or ionizable (capable of dissociating to form electrically charged particles) groups in a steroid molecule increase its polarity to an extent that is strongly influenced by the spatial arrangement of the atoms within the molecule.
