My Ultra Test only has 50ml of Prop and while there is no pain when injecting, the next 4-5 days are hell!
One pin in my quad (1ml) makes me unable to bend my leg more than a few degrees. But I've been sucking it up hoping my body would get used to it.
Pain & swelling still happens after almost 2 months of using Ultra Test.
I'm going back to Test E as I never had this pain using that.
And I noticed zero difference in using Test E or the Ultra Test as far as size / strength go.
No sides from either, just the incredible pain with the Ultra...
