Cycle after Injury

Hi All - thank you for reading this in advance.

I have just recovered from a bursitis / tendonitis injury in my elbow - went overseas for a month and feel fantastic. Been training for a couple of weeks now and back into it.

I was on a cycle earlier in the year up until the tendonitis injury 4 weeks in - thats right, I asked the pro's here on the forum and was advised to get off the cycle - just a 12 week Test cycle it was (I only did 4 and went off it).

Question for everyone - when is it best to go back on the cycle? Given it takes 3-4 weeks to kick in, it would be great to get back on it (mind you it was my first ever cycle!) as summer is approaching in Aussie land.

Cheers
