About MK Ultra
MK Ultra is a world-renowned indica cultivar bred in the early 2000s by Adam of TH Seeds in Amsterdam. Named after the CIA's infamous mind-control experiments due to its hypnotic, almost narcotic potency, MK Ultra crosses the mythical government-origin G13 clone with the West Coast titan OG Kush. The buds are remarkably dense and sticky, coated in a crystalline frosting of trichomes over dark forest-green calyxes with rich amber pistils. The aroma is pungent and earthy—combining chemical diesel fuel, pine needles, damp loam, and spicy Afghani hashish. Consuming MK Ultra delivers an unyielding, hypnotic body stone that dissolves severe chronic pain, muscle spasms, and insomnia.
