Torn between Grow Taller & AM5

[K-Train]

Hey there,

I'm quite keen on getting and using AM5, however I'm also very keen on using the Grow Taller sub. I'm a 23 year old guy, so I'm worried that the small window I may have to use Grow Taller may be closing.
Any recommendations, should I run Grow Taller now and see if it works, or should I risk using it 6 months from now after AM5?
Thanks

Get Grow Taller. Grab those extra 1-2 inches before your window closes. I'm the same age as you and I also feel that window closing.
