Reliable source for buying vials – which you can use as sprays when Limitless is out of stock. They are high quality, third-party tested & made in the USA.
To use as a spray you will need to also order a spray kit from Limitless. The kit comes with: Deionized water (10mL), a syringe, and a nasal spray bottle (that you can alternately use under the tongue)
For the Vials only, here are the links:
* You do not need to add reconstitution solution or Bac water to your cart. You are going to use deionized water for the spray.
Biolongevity also sells certain (not all) Khavinson Bioregulators, useful if Vita Stream is out of stock:
