Oral HGH does not, will not, and cannot work.  If it is a real hormone, it must be injected.  Your stomach is full of acid.  What happens to hormones in acid? They are "digested", ie they are dismantled by the acid into simpler form for absorption into the body.  Whatever action they may have had as hormones is negated.

Growth hormones. You need to get a test done at your doctor or specialist first.

Similarities:\n1. Both project effects to remote sites in the body.\n2. Both use negative and positive feedback systems. (e.g. The parasympathetic and sympathetic nervous systems and the hormones with opposite effects).\n3. Both project effects on each other.\nDifferences:\n1. The nervous system usually responds to events that require a fast response, and are short in duration, while the endocrine system is usually reponsible for handling/regulating long-term things. \n2. The nervous system projects its effects to a discrete region. The endocrine system generally projects body wide.\n3. Sorry I can't recall a third attribute right now.

Well, glands are technically organs. Glands differ from other organs in that their primary function is producing and secreting some hormone/substance

Parathyroid functions in control of plasma calcium and phosphate. Thyroid is an endocrine gland which secrets Thyroxine(T4), Triodothyronine(T3) and Calcitonin. The first two hormones function in control of metabolic rate, growth, brain development and brain functioning. The last one functions in control of plasma calcium. \nGood luck with your homework.

Hormones are a sensitive issue , everyone makes them at different levels , and we all react to them differently. It's what is in your own body chemistry that counts...your genes I mean.\nYou give 10 people the same doses of the same hormones and you can come back with 10 different reactions.\nI say why waste your time worrying about something in witch you can't nor would take back ...you've two beautiful children from it , enjoy life seems to fly by . One day your slipping on your slippers to get out of bed to start breakfast & the house is empty.\nBelive me I know , Enjoy your babies , soon they'll have their own.I've 6 grand-children and love'em all of them to piece's ~

hormones are molecules that act on cells to cause changes in cellular homeostasis.  Steroids are made from cholesterol (such as progesterone, testosterone).  Other horomones such as growth factors are proteins, others are small peptides such as insulin.

The endocrine system is all about hormones, and the nervous system coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions.

Vitamins A, D, and E are lipids.  They are stored in your body fat and released on an "as needed" basis.  The B complex and C vitamins are water soluble and therefore need to be replenished on a daily basis.  All vitamins are used as your body requires so adsorption is independent of intake.

The primary involved hormones are: Thyroxine(T4, thyroid gland), somatotrophine(STH, hypophisis), parathormone(PTH, parathyroid glands), calcitonin( thyroid gland), and dihidroxyde colecalciferol( D vitamin, produced primarily by the skin from cholesterol and sunlight).

In the molecular world of life, hormone is a molecule that 'signals wide-spread effects' while an enzyme 'enables local effects'.\n\nHORMONE IS A MESSENGER: It is a protein or other type (e.g., steroids) of molecule. It is released from one cell in the body, travels in the blood (in animals), reaches some other cell that 'responds'. In this target cell, there are 'specific receptors' that interact with this messenger-molecule and the cell 'responds'. For example, the skin cells in the face of a male teenager respond (grow hair) to several molecules of testosterone, a steroid hormone,  that are produced in testes. The entire process of response requires (a) availability of specific hormone, (b)its specific receptor as well as (c) the downstream series of reactions in the target cell. Different types of hormones cause different responses. \n\nENZYME IS A CATALYST: These molecules also act on very specific molecules (called substrates in this case) to produce an effect. The effects can be breaking a molecule, joining two molecules, modifying part of a molecule etc. In fact, these effects may never happen without an enzyme. However, the enzyme itself is largely unaffected and can be recycled. Mostly, enzymes are proteins and are not secreted through blood.

Vitamin is considered as a different subgroup of biochemical substances, with totally different chemical structure from carbohydrates, proteins and lipids.

UV light breaks down many vitamins. In the case of Vitamin D, sunlight converts beta-carotene into vitamin D and the level read by the test will be artificially high. \n   Beta carotene is safer to take than straight vitamin D because it is released slowly into the body so you don't overdose on it. The ones you can overdose on are the fat soluble vitamins A,D,E and K.

I take a multi-vitamin daily and I notice the difference when I miss a dose. Vitamins are a good dietary supplement if your diet is poor in vitamin-rich foods. But to specifically build muscle you need lots of protein. Chicken is a good source of protein if you like it (I don't mean the deep-fried stuff either). Good luck!
