Great product, can definitely feel the product working, and I haven't experienced any MAJOR side effects.
FITNESS OF USER: I am currently overweight, 14st 13pounds, at 5ft 11in and have been going to gym for 2 months with a low carb diet, and have lost 2st 11pounds before using jack3d. After using the product I can do a lot more at gym, thus increasing my calories burnt and helping me progress further towards fat loss.
TASTE & TEXTURE: The fruit punch flavour has a strange taste to it, but is easy to drink. I would compare the texture to a headache sachet, which you dissolve in a glass of water.
SIDE EFFECTS: Been using this for a week, no major side effects, only a headache when I first used the product, I'm not sure if jack3d caused it, but have not experinced one since. Another side effect is tingles, I had them at 1 scoop and 1.5 scoops, but not at half a scoop. They're a bit like low intensity pins and needles without the numbness.
FATIGUE: It takes longer to fatigue while using this product, enabling you to push yourself further. Weights also feel somewhat lighter, thus I'm able to do more reps & sets than normal, increasing more muscle mass to burn fat.
ENERGY: After 30 mins of taking the product, I'm ready to go to the gym and work my socks off. After a strenuous 1 hour 30 mins workout, I still feel like I have energy left to carry on with the day, meaning I don't feel tired, or about to 'crash'. However, it does feel like my body is tired, for example muscles feel like they have been worked, the product isn't jesus.
FOCUS: It makes you want to get the job done, no time for being idle while on this, all you want to do is workout.
OVERVIEW: Buy this if you are looking for an increase in energy to push you further towards your goals, whether it be increasing muscle mass or burning fat, just make sure you take it at least 5 hours before going to sleep, or you'll be awake quite some bit.
