Just a pointer, and this is not to assume you were not already aware, but If you weren't
If the patches you are getting a similar to the transdermal patch system of 10 years ago, which they likely are, why change them?, DONT THROW OUT THE USED PATCHES!!!!!!!!! The 50 mg indicates the amount of base testosterone you will receive as a DOSE over the course of 24 hrs. In order to set up a sufficient diffusion gradient across the multiple layers of skin before being picked up by the cardiovascular and lymphatic system it requires and don't quote me ( I had some in the lab at one time and I believe this was the content) a per patch base testosterone content of something to the order of 150 mg. So, don't chuck those patches, cut 'em open just like opiate addicts go at thier morphine and fentanyl patches. Squeeze out the jelly and rub it on your skin for an instant androderm type application.
Best of luck with the patches and use an antiestrogen at 150 mg per day, but I'm sure you already knew that. Or, I don't know what does everyone else think? approx 1000mg/week for 100 days........oh yah, I like letrozole, I've had excellent success with 200 micrograms per day (test/estra measured bi-weekly and ratio stayed VERY high) so don't waste the 2.5 mg you can get a lot more mileage out of them. These are all just opinions, I'm a lab rat, listen to the gym rats with the practical experience.
