Actually not necassarily so. Some Tribulus products would have you go on for 5 days and off for 2 or on for 4 days and off for 3. They do this to keep side effects low and to maintain the products effectiveness.
i've been stacking it with Haladrol-50 and prostanazol. i take 2 servings a day of the 17-hd, one before work out and one late afternoon. i keep this dose going on work out days and off days. yea like there is an "off day"!
yey though i walk through the valley of death i shall fear no evil! for i am the etc...
my roomate is taking 17-hd and I have not seen any gains in strength and size for this supplement all i see is increase in energy and he has been taking it for about 2 months straight now...i would not recomend this! I took it myself and did not get anything out of it! i switched over to mass tabs with halo tren 400 stacking them both worked wonders for me i got great gains in size and strenght! right now i just bought some 4-ad and 1-Androsterone with the Arom-x and the best liver suporter is Himalaya liver care it works very well!
