I'd recommend them, for me it's kind of hard to judge just how big of an impact they've made on my weight loss, but I have far greater energy, increased focus and generally feel great. I did take these with tauro test so not sure what they'd be like on their own.
I've also tried the reflex themo fusion and while the energy increase was about the same, I found my energy would crash after about 3 hours from taking.. like really crash to the point where I felt like sleeping. Never had this with Shredabull.
I also suffer from pretty severe anxiety issues due to experimenting with questionable substances over the last 12 months.. I was quite worried how i'd react on these as I remember suffering anxiety on previous strong fat burners in the past however I experienced no anxiety on these.
