Hi, I'm looking for someone who is willing to send me a few tablets of Yasko's General Vitamin Neurological Health Formula so I can try before committing to buy. I would be willing to send you a sample of whatever I have in exchange if you wish. I have stuff like Thorne Labs Basic Nutrients IV, taurine, magnesium glycinate, Beyond C, lithium, adrenal cortex extract, betaine hydrochloride, vitamin D3, neuromedulla complex, GABA (basically the same as theanine), Thorne B complex #6, Co Q 10, Kavinace, Caprylistat. Also kefir grains. I'm located in the USA, so US would be preferred to keep mailing cheap and simple. You can PM me to exchange details.
