If someone uses your referral code, you [the referrer] will receive 10% off your next order. The discounts stack! For example, if three (3) people you referred use your code in one month, you will get 30% off your next order (up to 100% off your next order).


If you [the referrer] are a current subscriber, your gained referral discounts will automatically be applied to your next renewal order. If you are a Buy-Once customer who builds up referrals, you will get an email with unique discount code(s) to use at checkout to apply the referral discounts gained.

LY-D6 is a golden color because it is a combination of the NAD+ booster and senolytic and is administered on two consecutive days per month.


LY-D2 is brown and it contains the daily NAD booster only.

Leap Years is a monthly regimen. On two consecutive days, you give the light-colored combination soft chews (from the bag inside the bottle (NAD booster and senolytic)). Daily after that, you give the dark-colored (NAD booster) soft chews (in the bottle) all the rest of the days of the month. We recommend starting the combination (light-colored) soft chews at the beginning of the month so it is easy to remember but you may start them on any two consecutive days of the month.


It takes about 4-6 weeks for senescent cells to develop, so the light-colored combination soft chew (NAD booster and senolytic) knocks down the population at the start of each month. Then, the dark-colored soft chew (NAD booster) supports the use of NAD for the healthy cells for the remainder of the month.

We have tested up to 10 times the daily dosage in a safety study in dogs and found no adverse effects. In the event of overdosage, please seek veterinary attention.
