Drop that Mk677 if you’re serious about leaning out. In addition to the bit of water you’re probably holding from it, more relevant is its doing your appetite no favors & especially it is harming your insulin sensitivity. It’s not a very good drug to stay on for more than a few weeks, maybe a couple months if you need the help bulking up.
Otherwise, mainly good for a bit extra recovery or waterweight or hunger in targeted niche scenarios, like you’re going to test your gym maxes in a few days and want to bloat up & get some extra carbs down.
