Purely OptimalWomen's and Men's Premium Multi Collagen Peptides Capsules (Types I, II, III, V, X) - Anti-Aging, Healthy Skin & Hair, Strong Joints, Bones & Nails

i received delivery on 02 Sept and started right away and followed the instructions. . i bought this type of collagen because of the good reviews, but i do not notice any positive result since I started taking the tablet. the box says i can order a free bottle by login in to Purely Optimal website, i tried many times but failed to order my free bottle., my bottle is almost empty and Im having seconds thoughts if i should buy again or switch to a different brand of collagen that is much more cheaper in price.
