Liquid, combined mix of 1-ad and 4-ad. Not sure of the quality and utilization of a liquid but it sounds pretty interesting. Since you are a mod Biggs, am I able to acquire some transdermal products through the "store" without a credit card? Anyway, what transdermal would you recommend as this type of product is very new to me. Used to the pill form of 1-ad and ErgoPharms select 300 (Norandrodiol). Again, your thoughts are appreciated.
