TestoFuel is an all-natural testosterone booster, meaning that it contains natural vitamins, minerals and amino acids. For this reason TestoFuel should have no negative side effects, at least on paper. But lets investigate further.
The dosage of each ingredient does fall within the recommended daily allowance suggested by the National Institute of Health. So the ingredient levels in each capsule are certainly safe.
The only way you could experience side effects from taking TestoFuel is by taking more than the recommended dosage which is four capsules per day. Please make sure you do not exceed this dosage level.
User Reports of Side Effects:
I could actually find no reports of side effects from users after scouring the internet and checking forums. This makes sense due to the natural ingredients contained in TestoFuel.
It seems that TestoFuel is a very safe testosterone booster to take. It contains only natural ingredients in safe dosage levels. There are no reports of side effects from users, at least that I could find.
