RS Transderm is going to be your best option for a transdermal product. The nice thing about RS Transderm is it contains both testosterone boosting ingredients and anti-estrogen ingredients so you won't experience any estrogen related side effects on cycle such as gyno, water retention etc.

Making your own transdermal product is not easy. You can't just apply raw steroid powders to your skin. If it was that simple, I don't think anyone would use injections.
