The 300mcg capsule is a convent once a day dosage for my son. Hyperlink helps improve those functions. Relatively safe and devoid of side effects.

Great product. Works fantastic. Highly recommend this vendor/brand.

This product should not be used by anyone and should be panned. The pull off plastic lid seal was gone. Use caution on mixing huperine a with whole ingredient caffeine plant like coffee/tea/….

I am amazed how markedly improved my memory and concentration have become. This product helps me focus and concentrate.

Clears away the fuzz and gets me going without side effects. I also notice that regular use it helps keep my lungs calm and happy. Upon researching each ingredient i am impressed by the myriad benefits each one offers.
