This is what I recommended to medical students doing rotations in my clinic if they don't have access to UpToDate (which basically everyone does now).

If this text is too basic, then Williams Textbook of Endocrinology is more comprehensive. Also Robbins & Cotran pathological basis of disease is basically the medical school bible for all diseases and covers endocrine disorders very well.
...though these may be a bit hard to get through without a good foundation in basic anatomy/physiology.
~~I need these books in PDF format, please pay attention to the edition because I need the specific editions listed below. Will pay $3 for each or $10 for both.~~ BOUGHT
~~1) Greenspan's Basic and Clinical Endocrinology, Tenth Edition~~
~~2) Vander's Renal Physiology, Eighth Edition~~
Ur right but not just because endorphines, actually is the way the endocrine system work and the impact of excersize on it.
Theres no need to look for research because well, is like if u need to learn about the lungs, u can read research about the impact of pollutants of the lungs, but if u want to undertand the lungs u will simple learn about the respiratory system. In fact pappers and research in the hands of most people instead of a tool to reach knowledge leads to a more severe and damaging form of broscience.
the problem here is people only thing in really simple terms about this things and if u try to explain them how the endocrine system works they cannot understand it beyond excerzise testosterone and the papers and webpages they read and missunderstood.
Ur right thoug. This all the sources u all need: https://www.amazon.com/gp/product/1259589285/ref=s9_acsd_top_hd_bw_bkg3aF_c_x_3_w?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-3&pf_rd_r=DHRN87QTJB5AB5Y52959&pf_rd_t=101&pf_rd_p=dc7f6090-c807-5092-ab5d-5fb62b4ea1e4&pf_rd_i...

Im tired of people here only knowing about sports and testosterone spreading disinfo because they read an article writing from an scientific paper they failed to understand.
