GoldenGirl, to elaborate, cycling on & off will give you back the jolt you get in the beginning if the 'effects' tend to fade, but the fat burning is a constant.
I'm reposting for the new users to TREX, yohimbine hcl & synephrine combo may cause Nausea/Queasiness, so it is recommended that you NOT take the dose on an empty stomach (i.e. the fiber in a banana usually helps prevent this) esp. if it's your 1st time.
Hahaha ahhh memories ... I was finally able to get 1 T-Rex down without some fiber (i.e. banana) so I tested out 2 caps on empty ... mid june, 80 at least, I'm decked out in sweats b/c I was freezing from the recent application of YES, pulled into gym's parking lot, head hangin' out the door all the H2O I pounded .... Sure enough after 10-15 minutes, I had his SURGE of energy for an awesome leg day + some sprints Fukkenshredded style ... Learned my lesson
