You have two possibilities.
1.) you already produce sufficient none that even though Ammo is buffered it may not be buffered enough. Adding a spray of Shine and a spray of either IO or IH should remedy that.
2.) in college classes you may not be in an environment where people are comfortable with Ammo. While it contains a small amount of respect/rone it also has sexual none and fun chatty nol. Tone down the fun and sexy vibe with a more mature and serious vibe like with a Shot of IG and IH.
