AF Store is where to find it.
I had decided to leave this issue alone, but since Ulter feels compelled to spam, I feel compelled to mention that with typical transdermal delivery, drugs that penetrate the skin barrier and traverse the epidermis and dermis are rapidly taken up by the dermal microvasculature, where they are delivered systemically (just like with orals) -- this is very well characterized in the literature (1,2,3) -- with direct tissue penetration being limited to 1-4 mm, which obviously is not exactly deep into the adipose tissue.
Let me repeat, if nothing is done to bypass the dermal microvasculature, our drug enters systemic circulation before it ever reaches the adipose tissue.
And, considering that Yohimbine HCl has good oral bioavailability, if the dermal microvasculature is not taken into account, we end up with a product that not only does not localize delivery, it does not even deliver it systemically as efficiently as an oral would do.
Considering these products cost far more than there oral counterparts, and could also be thought of as inconvenient in that you have to rub them on your body, wait for them to dry, etc., any supplement developer who does not take dermal uptake into account has obviously missed the boat quite badly.
And, guess what... there is only one substance I have seen in the literature that facilitates this.
And, guess what else... Yohimburn's formulation does not employ it.
