ARGIPREG is basically L argine which gets converted to nitric aci in body which results in vasodilation
and hence incresed blood flow.This is used by doctors for improoving blood flow in patients suffering from erectile dysfunction
It is supposed to increase the production of growth hormones in body but it has not been approved by FDA for it's use in increase of height.
of long bones in a male gets fused by the age of 21 to 22 years and so there appears very slim chances of getting increase in height.
However by good healthy diet,regular exercises ,yoga
,proper sleep,one can add few inches to his height.
I would advise you to consult a endocrinologist
and discuss this issue with him.
