Question 2

As noted above there is an expiration date on the syringe. What is the expiration date on yours?

Accepted Answer

The exp. date is located on each syringe. The newer syringes (as of Jan. 2016) have the exp. date in a readable format on the lip of the syringe where the handle enters the body. Older syringes have the exp. date inprinted on the round body of the syringe near where the handle enters the syringe. Is is encoded with a letter (batch identifier) and 3 digits, example: S127. Last digit stands for a year of expiration and the two digits after the letter is the exp. month. In the example provided the exp. date is December of 2017. NOTE: It is not 2007 as many think, the gel can not last 9 years in a syringe, it will be all dried out. Our (Green Dot Sales) current exp. date as of Feb. 2016 is 12-2017. However, the exp. date changes month to month as we update our stock on weekly basis.Thank you.
