EFR 7OH Shot 15mg Mint

EFR+ has done it again, only this time in liquid form. They have isolated the 7-Hydroxymitragynine and loaded this 30ml bottle with 15mg of it! If you are interested in the science of it, see below!

7-Hydroxymitragynine, like mitragynine, acts as a partial agonist at µ-opioid receptors and as a competitive antagonist at δ- and κ-opioid receptors. It also acts on alpha 2 adrenergic and 5-HT2A receptors. *(Under 1% 7oh Limit)
