Modere Collagen Bundle for Liquid Biocell Skin - bundle is for 4 bottles. All bottles are new and never opened with plastic seal protectant on each one. Expiration date for all 4 bottles is 10/26/2024. October of 2024 expiration. Recommended dosage is a tablespoon a day and once opened keep in the refrigerator for best taste. One bottle should last approximately 30 days if taking recommended dosing of the one tablespoon. This is a great deal for a 4 month supply of collagen as they’re regularly $75 a bottle on the website. I used to sell these at a local gym and have extra inventory. This collagen is AMAZING and has helped my skin clarity, hair and nail growth, and overall skin texture/quality. I’ve used it for years!
