I too used the Sr9009 at 20mg per day for about 4 weeks and I loved it. Just like it says on paper i literally felt like this chemical did reset my body. I have been off a few days and still feel good and energetic, my sleep patterns have improved , I have leaned up and like Cagebreed said it has also recomped my body. I definitely feel like an improved version of myself.
I have been doing extensive research on this new chemical and no I don't think is what they hyped it to be , "exercise in a pill" that will make your muscles grow like if it was some sort of myostatin drug..not all! This chemical promotes fat Loss the same way weight lifting does. We all can agree weight lifting turns your body into a 24/7 calorie burning machine simply because when you lift weights you tear muscle fiber and during the recovery process the body uses up calories to repair itself, well this is how sr9009 works by binding to a gene called rev-Erva therefore stimulating and activating the m e t a b o l ic rate in skeletal muscle similar in effect to weight lifting. This process also involves the creation of new mitochondria cells, an effect caused also by the stimulation of the gene Rev-Erva, imagine hyperplasia at the cellular level(mitochondria) which in my opinion could be the reason of the long lasting burst of energy and endurance sr9009 causes. Like CageBreed said, stacking it with creatine would be ideal Since more ATP will come in handy.
Lastly I would like to say that by increasing your metabolism not only you can lose body fat but if you are bulking you can make better utilization of the food you consume therfore making better and faster , cleaner gains.
