Hey guys I was gona do a test cyp cycle for 15 weeks, but I will have some left over, so would I be able to do a 20 week cycle of cyp? Or will those extra 5 weeks even be beneficial, and actually work against me for being on for too long? Not sure wat to think of that length, Its a long acting one so it seems to be good on paper. But i'll let my lab rats answer that from experience, haha.
