Hey there, so I'm already running a cycle (thanks to the information on this website, I was able to put together a really nice Test Prop cycle that I'm seeing a lot of lean mass from).

I have a question that I wasn't able to find the answer to, though.

I have been on Test prop for about 7 weeks, and I'm down to my last vial. I have a vial of Test E, though... and I'm hoping to add it on at the end of the cycle.

Question, is it safe to do this? And if so, I know Prop is a short ester and Test E is a long ester... so when and how should I go about the transition from prop to E?

Thanks for your help, everyone.
