For myself since I am doctor supervised I preferred switching over to short esters like TestP, NPP, TrenA, MENT, etc. while blasting and resuming my normal TestC TRT once the blast cycle was complete. I have ran longer esters while blasting but the blood draw timing for TRT makes this more difficult to nail down.
FYI- it would not make a difference to my doctor because I made sure I was perfectly honest with him on day one. He even went as far as willing to monitor my labs while on cycle as long as I did not tell him where I got it and what I was taking.
If you are seeing good benefits from TRT why even consider doing anything else. If you are committed to cycling you could easily stay with a simple increased dosage of testosterone only. If it works why try and fix it? I received some of the very best results from just 500-750mg/wk of testosterone. 500 being my sweet spot.
We all love to experiment but the reality most of us are not seeing the maximum benefits of steroid use because of all the other factors that are holding us back from maximum results. I might sound like a hypocrite because of my past experiences but the truth of the matter is unless we make a living in this game no one needs all the other crap we are pumping into our bodies. I am a really good example of what not to do because I have a hyper curiosity to experiment on myself… thank God I have a lot more good experiences than bad.
