Since I've read conflicting info about the proper dosage, Lion has kindly cleared up the matter:
Thanks for the inquirey, all of the research chemical pump sprays are dosed at:
10 pumps = 1mL
So, with the Letro at 2.5mgs/mL, 10 pumps = 2.5 mgs. Which means 1 squirt = .25mgs.
Hope this helps and Happy Holidays. Thanks for the business
Lion
