If you wanted to try the Testogel sachets instead of Tostran, I don't think there are any supply issues with those yet, although as we know, shortage of one product tends to have a knock on effect on others. There is also Testim in the little tubes, which would be another one to enquire about. None of the other testosterone gels are suitable for women.
I never thought I would see the day when the men's products were in short supply!
