Comparison
L-Theanine vs Picamilon
L-Theanine
An amino acid found almost exclusively in tea leaves. Promotes relaxed alertness via alpha-wave promotion and GABA/serotonin/dopamine modulation. Pairs with caffeine in a 1:2 ratio to produce the most-validated focus synergy in the nootropic literature. Essentially no side-effect or interaction profile at typical doses.
Picamilon
Russian-developed compound combining niacin and GABA. Crosses the blood-brain barrier (which standard GABA cannot) and provides combined cerebrovascular and GABAergic effects.

Bottom line
L-Theanine (evidence A, safety 5/5) has a weaker evidence base than Picamilon (evidence C, safety 3/5). L-Theanine has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose L-Theanine if
L-Theanine is the better fit when your goal aligns with its mechanism (Crosses the blood-brain barrier within ~30 minutes of oral dosing) and the dose range (100–400mg) suits your protocol. Half-life is 1h.
Choose Picamilon if
Picamilon is the better fit when your goal aligns with its mechanism (Hybrid molecule of niacin and GABA) and the dose range (50–300mg) suits your protocol. Half-life is —h.
