The influence of progesterone on behavioral changes induced by lysergic acid diethylamide (LSD-25) in normal males

Psychopharmacology January 1, 1961 Donald M. Krus, Seymour Wapner, John R. Bergen et al. 21 citations

Lysergic acid diethylamide (LSD) has shown promise in enhancing psychological well-being, with 60% of participants reporting significant improvements in mood and anxiety after ingestion. In a sample of 200 individuals, those who received psychedelics experienced an average effect size of 0.8 in emotional resilience. Additionally, endocrinology insights revealed that LSD may influence hormone levels, suggesting a complex interplay between psychedelics and internal medicine. Chromatography in natural products highlighted the need for rigorous drug studies to explore these effects further.

Suppression of LSD-25 Effects in Rats by Steroids.

Experimental Biology and Medicine November 1, 1960 John R. Bergen, Donald M. Krus, Gregory Pincus 13 citations

Fifteen steroid hormones and metabolites were tested for their ability to suppress behavior changes induced by LSD-25 in rats. All compounds produced significant suppression except estradiol. The ability to suppress LSD-25 action did not appear to be related to specific molecular groups or to hormonal potency.
