By buying a combo of one bottle of First Endurance Optygen HP and one bottle of Multi-V you'll save 10% compared to buying them individually. After all, it's a rare occurrence that someone buys Multi-V without grabbing Optygen or Optygen HP as well, so we thought we'd package them together to make it more convenient and less costly to stock up on First Endurance's wildly popular daily supplements. Each bottle contains 90 capsules.
