Noen som har prøvd denne kombinasjonen?
Brukte dette da jeg bodde i Danmark på 80 tallet.

Kan det fremdeles kjøpes i løsvekt på apoteket?

Growth factors and muscle function
L-arginine supplements have been popular for years as promoters of growth hormone production in the human body. Clinical trials to test this idea produced little more than confusion until it was realized that very large doses (around 40 grams per day) are required when arginine is used by itself.16

Dual amino-acid supplementation with L-arginine and L-lysine, on the other hand, increases growth hormone levels without the need for large doses of either supplement. Studies using 1200-1500 mg of each supplement showed that significant increases in growth hormone levels take place in the blood from 30 to 90 minutes after consumption.12,13 It appears that the best time to take arginine+lysine is when one is resting ? not when one is about to exercise. Exercise itself causes growth hormone levels to rise, and this effect nullifies the advantage gained from the supplements.13

Muscle function in the elderly typically declines, regardless of the amount of exercise performed. Among the important causes of this decline are deficiencies in the growth factor ?IGF-1? (insulin-like growth factor) and the amino acid ?cysteine?. Supplemention with arginine and N-acetylcysteine (NAC) can correct these deficiencies. A clinical trial in 2003 showed that the muscular response to physical exercise in frail geriatric patients was ?strongly enhanced? by arginine+NAC supplementation.14

IGF-1 is a key promoter of muscle growth in people of all ages ? in fact, the growth effects of growth hormone and of anabolic steroids like testosterone may result from the induction of IGF-1 production in the body rather than any direct effects on the muscles by these hormones themselves. It is therefore of interest that the production of IGF-1 is promoted directly by arginine at doses somewhat smaller than that required to raise growth hormone concentrations. One study showed that 17 grams/day of arginine caused significant elevation of IGF-1 levels.8
