I don't normally use stimulants as I used to suffer from real bad anxiety and stimulants would sometimes trigger bad attacks. But I thought I would bite the bullet and try them pre workout as I was struggling with energy levels because of the dreaded trensomnia.
Not the best tasting liquid in the world but I would recommend putting it in a cup of juice or small bottle of juice and drink roughly 30 mins pretty workout.
The first time I had one I must admit I felt uneasy as I could feel it starting to work giving me slight rushes through my body and I noticed I started to feel warmer.
I decided to just get on with what I was at the gym to do and the energy and focus I had was very impressive! Make sure you have plenty to drink when using them as you will sweat buckets but not feel thirsty at the time.
I still have 12 amps left with it will save incase I need them again.
