I do know that the various bases used in the gels and creams have a lot to do with the absorption. For instance a study did show that Testim had much better absorption than
Androgel.
With creams I have heard that you want one that is non PLO based. Solutions Pharmacy uses a cream called "HRT Cream" which is a vanishing cream that is supposed to be better than other forms of creams.
You should, theoretically have less
DHT conversion if using a smaller area such as the hairless portion of your forearms and biceps, rotating these application sites. Keep the area you use smaller than a can of Coke if you can.
At this juncture, I would increase the amount of cream you are using since it is obvious you are not getting as much T absorption.
There is no need to rush off to do injections. Many guys are happy with creams, you probably just need to tweak your method a bit.
