I received my two samples yesterday and started them this morning. If taken at full dose they are good for 3 days. The energy supplement said to start with 2 to assess tolerance and then move up if needed to the max dose of 4. I took 2 caps this morning on an empty stomach and I would say it gave me a nice alertness equivalent to a cup of strong coffee. No jitters to speak of. Tomorrow I will be hitting up the max dose of 4 caps on an empty stomach to see where that takes me.
The Libido supplement has me taking 2 caps AM and 2 caps PM. Took my first dose this morning and will be downing the next shortly. I don't know how fast this will kick in but I will let you know what happens tomorrow.
