Well, my last cycle was aboutr 16 weeks of test e and deca(frontloaded my deca and ran prop the 1st 3 weeks).
Stopped deca a couple weeks before test.
250iu of hcg every 3 days starting 3rd week all the way through.
Adex then letro ed
Clen and eca used throughout (NO not at the same time)
pct with clomid
Recovery... SUCKED!!!
Sides... SUCKED!!! after about week 12
Dont really feel like I gained much more after the initial 12 weeks anyway and whatever I did gain at that point was not worth the additional sides.
Sex drive was shot for a long while(thinking it was the deca), had really bad acne for months after pct(still have some scars.
Whether a coincidence or not I ended up with a variety of problems(acid reflux causing breathing issues, little naggin injuries, etc...) All of which resulted in a loss of a good portion of my gains.
This time round I'm running Test Only for 10 weeks(combination of prop and enth but stopping enth at week 8 so that pct can begin right after week 10). Hoping this works out better, I feel like 16 weeks + another 2 before pct was just wayyy too long for me to be shutdown.
Just my personal experience though, I'm sure alot of guys run very successful long cycles.
