Creatine has been found to increase the replenishment of ATP stores in the skeletal muscles (22). It is attributed to a greater rate of phosphocreatine resynthesis during the rest periods. Higher sprint speeds reported (23). There have been numerous theories proposed as to why creatine is a benefit to short term high intensity exercise (24). One theory is that the increased amount of phosphocreatine, (PCr), can be used as an immediate buffer to ATP which reduces the dependence of glycolysis which delays the production of lactate and hydrogen ions during exercise thus prolonging the activity by delaying the onset of fatigue, (25).
I also urge you to go on caloric surplus “soon” and focus on muscle growth. From my own experience and the way you talked about your body sounded like me and what I’ve been through, you will not have an end. I always thought I looked like a pig and went on a big deficit and kept losing weight but then you never really stop or get where you want to because all you’re doing is dropping calories. If you can’t shake that last bit of weight, that last bit of flab, then building muscle will help reshape and fill out your body with some muscle. Then you can cut again after with much greater ease and not a lot of effort while still maintaining muscle and how you feel :)
