On July 21st I started my Test Recovery Stack and today I ran out of Sustain. I've been using 4 pumps a day for 20 days now, isn't it suppose to last another week at least? I know when I received my shipment the bottle wasn't completely full. I figured this was normal, because you do have to shake before each use. Started Endoamp the same day and have a pretty good amount left, at least at enough to get me through another 9 or 10 days. Anyone else have this problem? Kinda worried that my test will not fully recover.
