1P-LSD Research Context

Research has investigated the relationship between

1P-LSD

and LSD. Animal research reported LSD-like behavioural activity
following administration of 1P-LSD, while later human
pharmacokinetic research investigated the compound and its
conversion to LSD. :contentReference[oaicite:5]{index=5}

A 2020 human pharmacokinetic study reported that, following
oral administration in the study, LSD rather than

1P-LSD

was detected in serum and urine samples. The authors stated
that these findings supported the prodrug hypothesis. :contentReference[oaicite:6]{index=6}
