to make themselves better
they are lipid soluble and pass through the bilayer
Glucocorticoids and mineralocorticoids are secreted by the adrenal cortex of the adrenal glands in response to signals from the pituitary gland via the hormone adrenocorticotropic hormone (ACTH). Glucocorticoids help regulate metabolism and immune response, while mineralocorticoids are involved in regulating electrolyte balance and blood pressure.
Steroids make it easier to add muscle mass, which makes you stronger, which makes you play better. The better you can play, the more money you can make doing it.
By glands. Hormones are produced only by the endocrine glands, e.g., the pituitary, the adrenals, etc.. Hormones are "chemical messengers": they are sent by the glands to target organs and stimulate them to produce specific effects, e.g. the hormone thyroxin is manufactured by the thyroid gland to regulate the metabolism.

Steroid: One of a large group of chemical substances classified by a specific carbon structure. Steroids include drugs used to relieve swelling and inflammation, such as prednisone and cortisone; vitamin D; and some sex hormones, such as testosterone and estradiol.
Some do, sure. All Olympic tests and many sports tests test for hormones, both natural (loading) and artificial (doping).
some same sports as british people
Sports people take drugs because it increases muscle mass and your body will then produce more blood Some of the drugs taken by sports people are false hormones which make you more determined to win Peptide hormones, analogues and anabolic agents all increase the size of muscles or help growth. Diuretics allow you to lose weight by increasing the amount of urine you pass.
Some people play sports, who are they?
steroid hormones can pass easily through the plasma membrane, the hormones then bind to intracellular receptors which induce a metabolic pathway which later promotes transcription of a specific gene.
Some steroid hormones are able to pass directly through cell membranes due to their lipid-soluble nature. Once inside the cell, they bind to intracellular receptors located in the cytoplasm or nucleus. This binding initiates a cascade of cellular responses, ultimately regulating gene expression and affecting various cellular functions.
