You're guess is correct. He used to be 6" but added .5" thanks to bathmate. Idk if he still is since the last time we talked, he told me that he's not consistent w/ it anymore. Unfortunately, you lose gains if you stopped it after a long time.
I know that this is a Koda thread but last thing that I would share is that Jacob and Ryan are eskimo bros. So it's not impossible to say that maybe he's also like that with Koda.
TBH, Jacob is a good dude. It's just aggravating that he wont reply to messages after some time because this is just a side hustle for him. It's an on and off thing. He won't be back anytime for sure since he got a pretty good deal with brand deal/sponsorships and such.
