The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
Take one serving (1 scoop) of C4 Ultimate, mixed with 10-12 fl. oz. water 20-30 minutes before training. During your workout, it is recommended that you drink plenty of water or performance beverage such as Cellucor Alpha Amino to stay hydrated. Some individuals may experience a harmless tingling sensation, which is attributable to beta alanine. Use only as directed.
