This achievement can also be obtained by using a single Adrenaline Syringe, as using one puts your boost gauge to 100% automatically. I can confirm this works, as that's how I unlocked the achievement.
If you can't find an Adrenaline Syringe, you can also get to full boost by using either two painkillers (60 boost each), three energy drinks (40 boost each), or one painkiller and one energy drink (exactly 100 boost.)
