Arginine vs Citrulline for the evening
Arginine is Bulletproof recommended for the evening*
Though for NOx it is often said Citrulline is better.
How would it be to replace Arginine with Citrulline in the evening?
Perhaps Citrulline in the morning and Arginine in the evening.
(Practically Ornithine seems to be sold in a combination with Argenine, so its more practical)
*It seems Arginine is recomended for growth hormone, not really sleeping.
Ornithine is more relaxing.
