Here's the deal - you can only run an oral for a few weeks before it starts fucking with your liver, and it's going to shut down your HPTA and you are going to need PCT. Six weeks is about the max for most people, and that is really too short to be worth the effort. PCT is PCT.
Now Bill Roberts and some others advocate for shorter cycles, but that is blasting and cruising on injectables, so there isn't PCT.
The thing to figure out is your goals. What do you want to do? Improve strength, performance, mass? Then plan a cycle. I assume whomever you are talking about is considering a first cycle and is probably afraid of injecting shit into their body, as they should be. They most likely haven't maxed out their natty potential, haven't put in the work in the gym for a long enough period of time, haven't figured out how to eat, and are looking for a short cut. If that is the case, doing a cycle will be a complete waste of time and money. If it isn't, then they should just do a proper cycle of 500mg of test, with an AI, HCG, and a proper PCT. There are literally thousands of threads on this board about how to plan a first cycle.
