Does Infinergii make you stronger?

Yes and no. Your muscle strength is determined by the number of mitochondria per muscle cell and how many muscle cells you have. There is no technology that can develop mitochondria or induce muscle cell division. Therefore there is no supplement or drug that can make one actually stronger, they can only facilitate muscle recovery at best. 

Infinergii works mostly neurologically, so your muscles are unchanged. However, users have reported being able to lift more weight at the gym while taking Infinergii. This is due to 2 factors. Firstly, Infinergii puts the mind into a concentrated and relaxed state, allowing for one to concentrate their muscle power more accurately and without shaking when pushing at one’s maximum ability. Secondly, Infinergii helps with oxygenation of the blood and delivery to the muscles. Increased oxygen not only fuels the brain but also delivers more ATP for improved muscle contractions. In this sense Infinergii will allow one to push their muscles harder with less recourse.
