Baseline cortisol, prolactin, and L-tryptophan (L-TRP) availability may affect PRF and may also influence response to treatment.

At typical doses for each of these compounds, neurochemical studies suggest a continuum of serotonergic enhancement from tryptophan through the SSRIs, fenfluramine and MDMA having the largest effect.

5-HT release after fluvoxamine and fenfluramine was significantly diminished in rats on a TRP low diet, and significantly enhanced after fenfluramine in rats on a TRP high diet.

Finally, in a second set of mice, the same tryptophan diet was found to potentiate the aggression-reducing effects of fluoxetine and fenfluramine without disrupting motor performance.

However, the tryptophan supplementation significantly enhanced the reduction in ethanol intake induced by fenfluramine and fluoxetine.
