That study you posted about molecular hydrogen (also fucking weird study, pretty interesting) uses the term NAc to refer to the nucleus accumbens, not to reference N-acetyl cystiene.The two links I’ve just posted can somewhat explain the role of NAC in changing the reward system and assisting with abstinence. Something worth mentioning regarding MGLU2 activations ability to temporarily suppress reward, is that this can be taken as an investment. this is because temporary suppression of dopamine and other reward signals by MGLUR2 is met by tremendous sensitisation of the reward system shortly after. I feel like this Study i’m going to link, Which is about molecular hydrogen May still apply to how NAC can suppress euphoria when coadministered with a recreational drug.
Sucks when abbreviations get used more than once.
