I have done 10-18 week cycles and I have run ONE 5 week cycle and I loved it. My year is based around my annual physical and being off long enough to fool my doc and my life insurance underwriter (substantial policy on me) that I am 100% healthy. I've only ever had elevated liver values twice (once because the aforementioned mini cycle was Dbol and Test for 5 weeks, and once because I ran SARMS S4 in the open with no liver prophylactic because I didn't realize it was hepatoxic). I got muscle shape and strength gains for sure, and then took a short break before a Tbol/Tren E/Test E cycle that I am just finishing off with Halotestin. And a LOT of NAC for liver pro.
Only you can tell how your body will respond, but I do agree with Rich Piana, you have to cycle different drugs, different times for your body to not develop immunities to them. Just like any drug that is used long term, you will eventually need higher doses if you don't allow your body to return to homeostasis; look at the 250+ pound monsters doing 1-1.5g test and other compounds at a gram+/week, you think they just want to spend that money on AAS?
