Kratom Highest 7-oh powders?

[pnillyg]

hey so im fairly new to kratom been on and off for a few months now. Curious if there are strains with higher 7-oh as i recently tried it and enjoyed it alone. I see there is enhanced kratoms but dont quite understand the terminology and culture quite yet. Any suggestions? Is there a red vein with added 7oh? Please advise thank you fam
