P.S - Regarding the kalimantan speed ball it’s a 60/40 to red / white mixture. It’s quite potent the only way I can describe it as if it’s actual speed ball it’s slightly sedating in the first 1 hour and then gives a kind of energetic white feel as time goes on. For the right person they would really enjoy this but personally I only use red for sleeping and white in the morning. So it didn’t work out well for me. Still a great product regardless
