Ammonia caps

[Thaibox]

I know this was a fairly common thing back in the day. An old school lifter I train with sometimes always talks about the "good ol' days", when his buddy would crack an ammonia cap under his nose when launching a dead or squat PR. He wants to hit a dead PR day with me soon, and we're going to use these.

Anyone ever try them? Are they any help at all, or is there a reason no one really does this anymore?

I've never tried them but I've read they mainly lead of hyper-CNS stimulation and should only be used durring a meet since over-use could lead to CNS burnout and overtraining syndrome.
