Also known as d-lysergic<unk><unk>  and LSD
Similar to chemical properties of serotonin
5-HT2 agonists, mediating excitatory neurotransmitter release.
LSD also binds to dopaminergic receptors, contributing to its psychogenic affects.
5-HT2 agonists, mediating excitatory neurotransmitter release.
Known as one of the most potent psychoactive drug, doses of minimum of 25μg. Doses of 1 to 1.5 μg/kg produce psychedelic effects, with the “optimum” dosage for a typical fully unfolded LSD reaction is estimated to be in the range of 100–200 μg.
Route of administration can be PO (most common), IM, or IV.
PO: Usual Dose 100-250μg, Onset 30-45mins, Peak effect 1-2.5hrs, Total duration 9-12hrs
IM: Usual Dose 100-250μg, Onset 15-20mins, Peak effect 1hr, Total duration 9-10hrs
IV: Usual Dose 40-180μg, Onset 3-5mins, Peak effect 1hr, Total duration 9-10hrs
Tolerance to LSD-25 builds up over consistent use and cross-tolerance has been demonstrated between LSD, mescaline and psilocybin.
PO: Usual Dose 100-250μg, Onset 30-45mins, Peak effect 1-2.5hrs, Total duration 9-12hrs
IM: Usual Dose 100-250μg, Onset 15-20mins, Peak effect 1hr, Total duration 9-10hrs
IV: Usual Dose 40-180μg, Onset 3-5mins, Peak effect 1hr, Total duration 9-10hrs
