Being week 9 of your cyp cycle beast is a waste. Save it for your next cycle. Not sure of your goals though but stats would be best.... Read the stickies!!
One week is rather pointless. Im guessing your saying one week because your doing a 10 week Test C cycle? In all honesty I seen my best gains from test E weeks 6-12 so to me 10 weeks is a little short. If your looking for a little more bang you could run the test for 12 weeks total which would give you 3 weeks to run the beast. But to be honest your best bet would be to save the beast as a kick start to a future cycle and just finish your 10 weeks or extend to 12 weeks if your still making good gains like i was.
