tincture

Would agnus castus pharmaceutical herbal tincture have the same effect as the commercial vitex pills. The study that showed inhibition of prolactin in men at a certain dosage was done with an extract of the plant. What kind of quantity would be needed with a tincture? I know i should be using M just can’t…thanks

For athletic purposes I would use a proven product, e.g. the Solaray 400 mg capsules, or M (which also contains other ingredients.)

Different tinctures will have different properties, even if standardized (since the
standardization is not for all the active
ingredients.)
