Where have you seen that?Taurine is showing to increase prolactin in some cases, lysine is showing to increase cortisol.
I find it interesting that lysine inhibits 5HT1A and 5HT2A because LSD has very strong affinity for both and probaly inhibits them as well. I found the effects of high dose lysine to be almost identical to the afterglow of a LSD trip. I think Lysine could be a potential substitute for LSD microdosing and ergot derivatives for these reasons. Obviously they are different but have some similar mechanisms of action.

"...L-lysine (0.8 mmol/dL) inhibited serotonin binding to guinea pig corpus striatum 5-HT4 receptors by 9.7% but had no effect on other serotonin receptors. At 100-fold higher concentration (80 mmol/dL), which are non-physiologic, lysine blocked >40% of serotonin binding to 5-HT4 receptors but also inhibited binding to 5-HT1A, 5-HT2A, 5-HT2B. Binding results were compared to effects of L-lysine on serotonin-evoked ileal contractions. By itself, L-lysine had no contractile action on huinea pig ileal segments indicating a lack of serotonin receptor agonism. Conversely, L-lysine at a concentration (0.7 mmol/dL) similar to that which blocked 5-HT4 receptors reduced serotonin-evoked ileal contractions by 35% confirming its action as a serotonin receptor antagonist. A related amino acid, L-leucine did not modify serotonin-elicited contractions showing the specificity of L-lysine actions."
LSD binding affinities:
Binding affinities of LSD for various receptors. The lower the dissociation constant (Ki), the more strongly LSD binds to that receptor (i.e. with higher affinity). The horizontal line represents an approximate value for human plasma concentrations of LSD, and hence, receptor affinities that are above the line are unlikely to be involved in LSD's effect.
Note LSD has strongest affinity for 5HT1A and very strong affinity for 5HT2A
