Old Guy Needs Help with Testosterone Purchase

I am a 68 year old white male who has been on Testosterone therapy for about 5 years. I am currently taking 1.5ml (200g/ml) IM on a weekly basis. Numbers are right and my doc is happy.

I just lost my Rx coverage and need to find a place to purchase my medications for as few dollars as possible.

I can get most of my meds from various Canadian pharmacies, but am running into a problem with the Testosterone.

Simple question, I hope:

I need to buy Testosterone Enanthate in bulk for IM injection. I can get a valid US Script for it if necessary.

Can anyone offer a suggestion as to legitimate place to purchase this and give me an idea as to my cost.
