Yeah I use it often. It does increase appetite and in that way increases wieght. The energy is why I am taking it now. I am on a cut and it helps me keep going strong through 3 hours a day training.
The B vitamins form the "core" of many of the enzymes and intermediate steps of the Krebbs cycle and Oxidative phospholoration process' which makes our ATP. In very Laymans terms
I've tried both research grade and pharmaceutical B12 and never felt any difference and never felt all the energy and other good things your supposed to feel
i have taken oral and have never felt any difference. iunderstand the kreb cycle but with out calories to create energy b-12 would have no effect on the kreb cycle right?
for the painfull suspension injection like with testo susp or winny you can cut it with B12, but it dosent work with oily injection => oil and water dont mix very well.
