Personally, I would not take either. If I absolutely had to use a topical product, then it would be RS Transaderm, since it is very effective, and it already has an anti-estrogen included, so you basically get all in one product.
However, topical products in general are not good in my opinion because they are expensive, inconvenient (putting this cream on a daily basis...), you can transfer some of it to your close ones, and they are much more expensive than the injectable forms of testosterone. Therefore, it would make much more sense to do once per week injections instead of rubbing it into yourself everyday.
