Why do some of your products now list both a Manufacture date and a Best by date?
Traditionally, supplements were labeled with an expiration, "Best by," or "Use by" date-usually four years from the time of manufacturein accordance with the United States Pharmacopeia (USP) guidelines. However, the FDA's Good Manufacturing Practices (GMP) guidelines and regulations have been recently updated. Therefore, a number of Hammer Nutrition products now display a "Manufacture" date on the label (oftentimes listed as MFG).
For example, a product manufactured on January 17, 2012 will display "MFG 011712."
In addition, to make determining a Hammer Nutrition products shelf life more convenient for our customers, as of August 16, 2012, we are also including a "Best by" date on gels and powders. The "Best by" date is the recommended date by which you should consume a product for best results.
- Hammer Gel has a "Best by" date of two (2) years from the time of manufacture.
- All Hammer Nutrition powdered fuels and Perpetuem Solids have a "Best by" date of three (3) years from the time of manufacture.
Hammer Bars and Endurolytes Fizz will still list an expiration date on the label. For optimal quality and freshness, these products should be used/consumed prior to the expiration date, which is within the following time frames from the manufacture date:
- Hammer Bars 18 months (produced after 1/1/13)
- Endurolytes Fizz two (2) years
Hammer Nutrition supplements will list a "Manufacture" date on the label, shown as MFG. One should have no concern regarding the quality or freshness of our supplements, as long as the product has not aged more than four years since the MFG date shown on the bottle or label (making sure that products avoid excessive heat and/or sunlight).
