pro colloidal silver and gold and copper ( actually all their products ) have helped either me or my family and friends who have bought their products with a number of health issues . its been a `` miracle `` worker for psoriasis , hair issues , and a host of other things to say the least . the team are very `` on the ball `` at their job and have a very good sense of commercial business and how to keep the Customer happy . they rapidly correct any errors and are a pleasure to shop with , their prices are correct even though their shipping is a wee bit steep at times ( that dépends what you buy of course ) , I`m an international Customer and really appreciate their international service as you can`t find these products for sale everywhere . alwasy a good reason for me to come back . sincerely pleased . good job guys .
