I think 2g sarcosine have the same effect as 60g glycine.
“Sarcosine is a natural amino acid that has already been shown to reduce positive, negative and cognitive symptomatology in chronic as well as acute schizophrenia patients. Advantages of sarcosine vs. glycine site agonists use include the relatively low dose required and the lack of known side effects.Jan 13, 2006”
Sarcosine is stronger version of glycine bcz it blocks glycine breakdown and activates NMDA receptors at the same time:
“It acts as a type 1 glycine transporter inhibitor and a glycine agonist.”
"Sarcosine is ubiquitous in biological materials and is present in such foods as egg yolks, turkey, ham, vegetables, legumes, etc.
Sarcosine, like the related compounds dimethylglycine (DMG) and trimethylglycine (TMG), is formed via the metabolism of nutrients such as choline and methionine, which both contain methyl groups used in a wide range of biochemical reactions. Sarcosine is rapidly degraded to glycine.
Taking selenium alone seem to have some effect on negative symptoms. I think its because of better thyroid activity. Selenium helps to convert inactive T4 to active T3.
One day I took two pills and that day hard to fall asleep and full of sex thoughts, everything appeared so vivid. Almost like some hypomania feeling. Erection is rock hard it not going away. I think its the best erection pill.
