I just started a 12 wk cycle of Test Cyp. I have been on Test Cyp, for approx. 6 mo, my levels have varied throughout. At this point my last test was not too stellar at 315. The highest it's been is 640, but that was a month starting TRT. I have been consistent with my weekly treatment, so I am at a loss as to why my levels are not consistently going up. No alcohol, clean diet. I am well-versed in AAS, just an advid reader. I subscribe to the Mentzer style of training, but with a bit more volume. That's a side issue. In short, I have increased my dosage to 400mg twice a week. 3.5 day split. Just want some feedback from anyone that has had a similar experience.
