Ive read the inside of the upper arms and forearms are high absorbant areas. like wise a shaved calve and the area right below the calve also are high intake.
Primordial performance touts with their dermacrine alpha to apply to the shoulders and upper back since this is where a majority of the enzymes neccesary for conversion to target hormones are located.
Youd be best served to use all spots since your going to be applying a hefty amount with two transdermals...
Id go, 1-2 pumps left shoulder/upper back, 1-2 pumps right shoulder upper back, 1-2 pumps inner bicep and forearm (both sides with hier own pumps) and then to the legs.... if you dont want to shave them then just apply to upper chest and collar bone area.... Im sure youll haave to use ALL of these spots.
Enjoy!
