Perfect Prep EQ Gold Paste uses natural ingredients in a proprietary blend to create sustained relaxation and focus in horses during stressful conditions. Perfect Prep EQ Gold acts gradually. Its effects peak 8 hours after first administration, and last up to 12 hours. Gold can be used repeatedly for indefinite periods, as horses respond without building tolerance, and its effects maintain or increase with continued use. Horses may remain focused and tractable for days after last adiministration. Contains Magnesium, Thiamine (Vitamin B1), Inositol, Taurine and Amino ProPanoic Acid. 60 cc syringe.
