I did a series of short cycles about 2 years ago, 2 on/4off, 3-4 times. I was using Cut Mix, 50mg each of tren a/test p/mast p, shooting 1ml per day putting my total weekly use a shade over 1 gram. I did a log, you should still be able to find it on here.
I liked the results I got from this, but my diet wasn't dialed in as tight as it should have been - so I didn't lose much fat, just put on muscle and strength (benched 370 for a good single, highest I've ever done BY FAR). Each two week cycle I would gain around 10 pounds, then during the 4 weeks off I would drop about half of that. After 3-4 of these, I ended up about 10-15 pounds (give or take) heavier, noticeably bigger and more muscular, but didn't get cut up or shredded (again, diet). First two weeks off were PCT, forget exact dosing I used but it was Nolva. Still felt good and strong the first week or so after coming off, to the point of still making strength gains without adding any size. The fourth week off, right before going on again, usually felt like crap. Slight loss of motivation, not too serious; was able to move the weights I had planned but still felt weaker if that makes sense.
Biggest issue was about a month or two after my last short cycle, I felt like I crashed - loss of drive, started having trouble meeting my prescribed weights, felt run down most of the time. Did another PCT of Nolva 40/40/20/20, and that got me back on track. Everything I had read at the time said I could start PCT 2-3 days after last inject due to short esters, but in retrospect I probably should have waited a few more days or even a week, and should have done a full 4 week PCT after the last one. I may do these again in the future, and I'll try to remember those pointers if I do.
If you were going to follow a similar plan, I would do this:
week 1 - no injections, no PCT, letting short esters clear
week 2 - PCT, 40mg Nolva
week 3 - PCT, due to short nature of this, not sure if it would be better to stay at 40mg Nolva or drop to 20mg for second week
week 4 - PCT finished, waiting this week before starting again
I don't think 2 week cycles will do much as a stand alone, but a series of them should give you good results. Also, after the last of your series, I would wait a week again and then do a full 4 week PCT. I don't know it for a fact, but I think that would have helped with my recovery after the last one. Also, one of the biggest keys to success with this strategy is high amounts of gear, 1 gram or more per week - I want to say Bill Roberts chimed in on another thread about this and supported that statement. You're only on for a short time so you have to be aggressive in that area, without being stupid.
