The less time you spend off the higher the chance of damaging your HPTA.
Less time off also gives less time for your Lipids and RBC etc to return to normal although without blood work its impossible to say how these health markers are being affected.
Cycles ran in quick succession may also be less effective than a cycle after a period of 8-16 weeks off. This is why people do not stay 'on' forever, along with health concerns. If people do not want to PCT then they would blast and cruise i.e. 8-16week cycle followed by a running a high TRT dose for a similar period of time.
Blasting and cruising is very different from running cycles and is not something that i would suggest unless necessary for you goals or if you are already on TRT.
