Have you ever wondered what exactly is up with steroids for sale? This informative report can give you an insight into everything you've ever wanted to know about steroids for sale.
Contrary to popular belief, steroids are not produced by the human body alone and steroids of varying complexity are produced by plants, animals and even primitive organisms like fungi. Although steroids are classified based on their chemical structure, steroids can also be classified on the basis of their function in the human body.
There are essentially three major ‘sex’ steroids produced in the human body: progesterone, estrogen and testosterone, all three are commonly known as hormones but are essentially steroids. The three steroids mentioned above are produced by both males and females in different quantities, and have different functions.
Estrogen
Estrogen is responsible for development of female secondary sexual characters like breasts and plays a vital role in the female estrous cycle. Estrogen is produced by the ovary and is also a major ingredient in contraceptive pills. Like most steroids in the human body, the level of estrogen fluctuates on a daily basis. Since estrogen plays a vital role in female menstruation, estrogen levels fluctuate with the female menstrual cycle. Apart from the major function mentioned above, estrogen is also responsible for regulating fluid balance, accelerating fat build up, increasing bone growth and causing reduction in muscle mass.
As a steroid, estrogen is primarily used in oral contraceptives and in fertility treatment, recent studies have also shown a close correlation between estrogen and certain types of breast cancer (almost 80% of all cancers require the steroid estrogen to perpetuate and grow).
Progesterone
Like estrogen, progesterone is a steroid hormone whose levels fluctuate with the female menstrual cycle. Unlike estrogen, progesterone is not responsible for development of secondary sexual characters but plays a vital role in the female menstrual cycle. Progesterone is responsible for promoting ovulation and also helps the body cope with the muscular cramps and bleeding associated with the menstrual cycle. Progesterone is primarily used for Assisted Reproductive Technology (ART) cycles such as In-vitro Fertilization (IVF). Progesterone is also being used for experimental treatments involving multiple sclerosis and for controlling brain damage. Interestingly, progesterone is produced in small quantities in the male testis also.
You may not consider everything you just read to be crucial information about steroids for sale. But don't be surprised if you find yourself recalling and using this very information in the next few days.
Testosterone
Testosterone is a male sex hormone (androgen) that is responsible for development of male secondary sexual characters like body hair, deepening of voice and increased muscle mass. Testosterone is produced in minute quantities in the female ovaries and excessive production of testosterone in the female body also results in development of ‘manly’ features. Testosterone also helps protect bones from osteoporosis and is the reason why the incidence of osteoporosis is much higher in women.
