The Science


The carefully calibrated andropause formula in Provacyl has been optimized, based on the most current emerging medical research into anti-aging.

Here is a sampling of the DOZENS of peer-reviewed scientific studies, trials, and articles that have appeared in prestigious medical journals over the past few years including studies that support the individual ingredients included in the Provacyl formula.

Clincial Studies in HGH Elevation

Effectively Turned Back The Clock 10-20 Years!

“The effects of six months of human growth hormone on lean body mass and adipose-tissue were equivalent in magnitude to the changes incurred during 10-20 years of aging.”

Daniel Rudman, M.D., in the New England Journal of Medicine

Could Prolong Patients’ Ability To Live Independently!

“Replacing GH, or stimulating GH with GH-releasing hormone or a GH secretagogue could confer benefits in normal aging… in particular, could reduce the loss of muscle mass, strength, and exercise capacity leading to frailty, thereby prolonging the ability to live independently.

… Preliminary reports of improved cognition are encouraging…”

Hersch EC, Merriam GR. Clin Interv Aging. 2008;3(1):121-9.

Beneficial For Metabolism And Psychological Well Being!

“Replacement therapy with Growth Hormone has shown beneficial/normalizing effect on parameters such as cardiac and renal function, thyroid hormone metabolism, bone metabolism, sweat secretion, total and regional fuel metabolism and psychological well being.”

Dr. Jorgensen and Dr. Christian of Copenhagen, Denmark European Journal of Endocrinology, 1994

Hersch EC, Merriam GR. Clin Interv Aging. 2008;3(1):121-9.

“Indirect evidence suggests that GH are of importance in developing muscle strength because young adults with GH deficiency have reduced muscle mass and strength.”

Lancet 1989; i: 1221-1225

“Beneficial effect of growth hormone treatment in GH-deficient adults.”

Quality Of Life Was Improved!

“GH therapy improved the QOL [quality of life] similarly in elderly GH-deficient patients and younger counterparts.”

Clin Endocrinol (Oxf) 2000;53:281-289

PROVACYL INGREDIENT: Dehydroepiandrosterone (DHEA)

Study: DHEA Supplementation and Metabolism

“Many animal and human studies show that supraphysiological doses of Dehydroepiandrosterone (DHEA) can influence body composition and carbohydrate and lipid metabolism.”

DHEA Replacement in Healthy Men with Age-Related Decline of DHEA-S The Aging Male (Journal), 2003; 6(3):151-156

Study: DHEA and the Immune System

“Administration of oral DHEA at a daily dose of 50 mg to age-advanced men with low serum DHEAS levels significantly activated immune function.”

Activation of Immune Function by Dehydroepiandrosterone (DHEA) in Age-Advanced Men; The Journals of Gerontology, 1997; 52A(1):M1-M7

Study: DHEA and Abdominal Fat in Men

“DHEA replacement could play a role in prevention and treatment of the metabolic syndrome associated with abdominal obesity.”

Effect of DHEA on Abdominal Fat and Insulin Action in Elderly Women and Men:

Journal of the American Medical Association, 2004; 292(18):2243-2248

Study: DHEA and Treatment of Memory Loss

“In both studies, improvements in depression ratings and memory performance were directly related to increases in plasma levels of DHEA and DHEA-S and to increases in their ratios with plasma cortisol levels. These preliminary data suggest DHEA may have antidepressant and promemory effects and should encourage double-blind trials in depressed patients.”

Lancet 1989; i: 1221-1225

DHEA and Treatment of Depression Biological Psychiatry, 1997 February; 41(3):311-318
