Does glycine raise prolactin?

The central actions of glycine and strychnine on prolactin and LH secretion - PubMed

Unanesthetized diestrous female rats were tested for the prolactin response following an intraventricular injection of several doses of the neuroinhibitory amino acid glycine, and the antagonist strychnine. Glycine in doses of 1.0 or 0.1 mumoles increased pituitary prolactin release...

Glycine is known to increase GH in a fasted state, because it drops blood sugar. Prolactin and GH are usually released together. Plus, they infused glycine in this study.
If you take glycine in reasonable doses in a fed state without it dropping blood sugar, then it shouldn't increase GH or prolactin.
