Did anyone use such things? Are they good? What do they actually do to you? Are they safe? Do they have dangerous side-affects? This stuff on the site looks very dangerous to me.
Please inform me of such things, if they really are good I may be interested in the future in buying different things if they are really good and make you healthy and such.
I would be carefully with all such substances.
Make a good research before you order such a thing and look for side effects (most of them don't have any effect anyway).
Neither you, nor your body does really need any of them.
Only thing I take for example is
Creatine, which is actually save (in small doses)and proven to have positive effects (if you make sports):
Extensive research has shown that oral creatine supplementation at a rate of 5 to 20 grams per day appears to be very safe and largely devoid of adverse side-effects,[22] while at the same time effectively improving the physiological response to resistance exercise, increasing the maximal force production of muscles in both men and women.[23][24]
Improved cognitive ability
A placebo-controlled double-blind experiment found that a group of subjects composed of vegetarians and vegans who took 5 grams of creatine per day for six weeks showed a significant improvement on two separate tests of fluid intelligence, Raven's Progressive Matrices, and the backward digit span test from the WAIS. The treatment group was able to repeat longer sequences of numbers from memory and had higher overall IQ scores than the control group. The researchers concluded that "supplementation with creatine significantly increased intelligence compared with placebo."[33] A subsequent study found that creatine supplements improved cognitive ability in the elderly.[34] A study on young adults (0.03 g/kg/day for six weeks, e.g., 2 g/day for a 70-kilogram (150 lb) individual) failed to find any improvements.[35]
And there are signs that it may even extend the lifespan of mammals:

But I didn't find it in that shop anyway.
