Steroid hormones in human body

Erythropoietin (EPO): A 165 amino acid glycoprotein hormone (glycoproteins consist of several sugar molecules linked with a protein molecule). EPO stimulates erythrocyte (red blood cell) production in the bone marrow, boosting the blood's ability to carry oxygen. Studies have shown that significant amounts of EPO resist digestion and survive to reach receptors in the intestinal tract. One raw milk-drinking athlete was wrongly accused of blood-doping, so there's at least anecdotal evidence of EPO's activity in our systems!

If you're a performance enhancing athlete and you tolerate little phrases such as human growth hormone steroid you're only aiding in perpetuating ignorance. Of course most are afraid to say anything but there's no reason to be; there's nothing against the law regarding speaking, there's nothing against the law regarding sharing facts and opinions. The truth is simple and if most understood the basics of these truths we would begin to see a change, we would begin to see an end to the hysteria. The next time you hear someone refer to HGH as the human growth hormone steroid correct them and when you do you'll more times than not peak their curiosity. When you peak someones curiosity this opens the door for true discussion and this is your opportunity to shed some light on a subject that is important to you.

Radioimmunological methods have been employed for the simultaneous determination of dehydroepiandrosterone, androstenedione, testosterone, oestrogens (oestradiol + oestrone), progesterone, 17 alpha-hydroxyprogesterone and cortisol in human adipose tissue and peripheral blood to compare the hormone pool of adipose tissue with that in the general circulation. Extremely high steroid concentrations in the adipose tissue and hormone pool in the fat of obese subjects were observed. For adipose tissue/serum steroid ratios, the highest values were obtained for dehydroepiandrosterone and the lowest ones for cortisol. A preliminary study showed a great accumulation of steroids in adjacent adipose tissue of breast tumors. Striking differences were observed in the adipose tissue steroid concentrations between benign and malignant mammary tumors. The present findings revealed that blood hormone determinations may be insufficient to consider the steroid hormone availability in various endocrinopathies or steroid responsive tumors, especially when the endocrine state of extremely obese subjects is observed.

As part of a program to explore whether a relationship existed between the compounds present in breast cyst fluid and the risk for breast cancer, concentrations of a wide variety of hormones, enzymes, tumor-associated antigens, and ions in breast cyst fluid were determined. In this report, the concentrations of steroid hormones in cyst fluid samples from the same population used for previously published studies of peptide hormone concentrations were measured. This study determined the levels of cortisol, progesterone, testosterone, dihydrotestosterone, androsterone, androsterone sulfate, dehydroisoandrosterone, dehydroisoandrosterone sulfate, estradiol, estrone, estradiol sulfate, and estrone sulfate. In previous studies, levels of peptide hormones were shown to be elevated in breast cyst fluid, and in this study, the levels of the 4 17-ketosteroids and the 2 estrogen sulfates were markedly elevated in the breast cyst fluid over the plasma level. The concentrations of the other compounds were either the same or only slightly higher than plasma levels of the same compounds. To date, however, no correlation has been obtained between the occurrence of breast cancer and levels of any of these assayed hormones.
