1cP-AL-LAD

1cP-AL-LAD (1-cyclopropanoyl-AL-LAD) is a synthetic psychedelic of the lysergamide family and the N1-cyclopropanoyl ester of AL-LAD (6-allyl-6-nor-LSD). It is strongly believed to function as a prodrug for AL-LAD, with rapid esterase-mediated cleavage of the cyclopropanoyl group releasing active AL-LAD in vivo. The compound appeared in the research chemical market as a legally distinct alternative to AL-LAD in jurisdictions where that compound had been specifically scheduled.

AL-LAD occupies a distinctive place among lysergamides for its shorter duration (6–8 hours versus 8–12 hours for LSD) and its reputation for a more colorful, playful, and visually vivid character compared to LSD's more analytical and introspective tone. Community reports for 1cP-AL-LAD consistently mirror the AL-LAD profile: a faster-moving, more sensory and social experience with slightly reduced philosophical weight. The allyl substitution at the N6 position appears to produce faster receptor dissociation kinetics compared to LSD's N-diethyl structure, contributing to the shorter duration.

1cP-AL-LAD has been reported by users to have a smoother onset compared to AL-LAD directly, consistent with the prodrug conversion step adding a slight delay. It has gained a reputation in psychedelic communities as an approachable lysergamide for those who value shorter duration or prefer a lighter, more visually-oriented character. Community reports of challenging experiences generally describe them as less philosophically confronting than LSD but potentially more disorienting visually.

Testing with Ehrlich reagent (purple/violet reaction) is essential before use. As with all research chemical lysergamides, the long-term safety profile has not been formally studied, and the risks are extrapolated from the broader class.
