There are several nutrients and prescription drugs which cause GH release. These include the amino acids arginine and ornithine and the prescription drugs L-Dopa (another amino acid), bromocriptine (Parlodel®, by Sandoz), and vasopressin (Diapid®, Sandoz nasal spray). In one study, 1/2 gram per day of L-Dopa increased the growth hormone output of men in their […]

The dangers of birth control pill use have been grossly exaggerated. Note in the figure below that the mortality associated with birth control pills is lower than the mortality associated with the use of no birth control at all ages except for smokers over the age of 40. Up to the age of 30, risks […]
Without such treatment, many—probably most—post-menopausal women will experience pain, burning, and soreness during intercourse, particularly if it is prolonged or frequent. (A small percentage of premenopausal women also suffer from this problem.) In our limited experience, the following topical formulation works well: 1/2 to 1 percent testosterone cypionate plus 0.1 percent estradiol dipropionate in any […]
In spring a young squirrel’s fancy turns because the days are getting longer, and exposure to longer light periods sets off a chain reaction involving the brain and pituitary gland, resulting in release of hormones that affect sex hormone levels and in turn cause the sex glands to enlarge and produce their sex hormones. —Joseph […]
Science consists in grouping facts so that general laws or conclusions may be drawn from them. —Charles Darwin Sleep is a complex state controlled by a number of different brain chemicals. In aged individuals, these brain chemicals may not be made in as great a quantity as in youth. Brain cells may become less sensitive […]
Although male pattern balding isnot necessarily tied to old age, it is very definitely due to a clock. If you transplant hairs from the balding area onto another part of the head, these hairs fall out right on schedule with the others remaining in the balding area. If you transplant hairs from nonbalding areas to […]
Old people often suffer from a deficiency of serotonin, an important inhibitory neurotransmitter that initiates sleep.

Sleep disorders are common in old age, including difficulties in falling and staying asleep. Irritability and bedtime flights of ideas may occur. Tryptophan, an […]

Pathway for synthesis and metabolism of serotonin. In similar studies in rats, life extension was produced by giving oxytocin alone. Low acetylcholine levels contribute to the forgetfulness and lack of ability to concentrate which often occurs in old age. The cholinergic nervous system also controls the sensory input; too little acetylcholine and you are easily […]
