I've never heard of this. Do you have some extra androgel? Otherwise, ditch the idea as this is not a good idea. Most prefer injects (on these sites anyway) and adding the "a-gel" would be redundant.
Incidentally, I pay $5 for a 20 week supply of T cyp..I've heard androgel being as much as $300+ w/"good insurance.
I'd google the subject and if it rendered nothing objectionable I'd consider it...if I were inclined.
