I will say this from a retailer standpoint. I've sold a buttload of 1-AD. I sold a buttload of sauce when it came out (due to fact wholesaler was out of 1-AD). I've had many comments to the fact of "sauce didn't work as well as 1-AD". That or they mention the gains that got and they just don't add up to what it should when compared to 1-AD. If you want oral go with 1-AD, if you want 1-test transdermally Par's product has worked great for my customers.
