text: Yo, check it out, I got some knowledge to spill,
  About serotonin synthesis, let me give you the deal.
  Depends on tryptophan levels in plasma, you see,
  But to boost that mood and cognition, gotta increase it by 40%.
  
  In this study they went deep, investigated the effects,
  Of a TRP-rich hydrolysed protein, no time to neglect.
  They used egg-protein hydrolysate, that's the EPH,
  To see if it could raise TRP:LNAA, let's see what they say.
  
  They wanted to know if it works with 2 grams of milk protein too,
  So they mixed it up and tested it, just to get a clue.
  In a double-blind crossover, they had twenty subjects strong,
  Ages around 52, ready to prove them wrong.
  
  They measured amino acids in plasma, every half an hour,
  For three and a half hours, they had the power.
  They gave 'em different doses, 4, 8, and 12 grams of EPH,
  With TRP amounts of 270, 560, and 800, the best.
  
  They also tried 4 grams of EPH with 2 grams of MP,
  That's milk protein, if you didn't catch the key.
  And they had 4 grams of MP alone, just for comparison's sake,
  To see if EPH was the real deal or just a fake.
  
  All three doses of EPH showed an increase,
  In TRP:LNAA by more than 40%, now that's a feast.
  At 30, 60, and 90 minutes after they drank,
  The levels were rising, no time to yank.
  
  Compared to 4 grams of EPH alone,
  The combo with 2 grams of MP had a lower tone.
  At 60 minutes, the increase was significantly less,
  But at 90 minutes, they were both in the success.
  
  So even a low dose of 4 grams of EPH,
  With 2 grams of MP, can make your TRP:LNAA take a step.
  Above that 40% mark, it's a viable ingredient indeed,
  To boost TRP availability, that's what we need.
  
  So there you have it, the study's conclusion,
  EPH is the real deal, no need for confusion.
  Boost that serotonin, elevate your mood,
  With EPH and MP, you're on the right route.
