Just my experience with NPP. I like to be able to get off quick if something comes up. I cant do test unless i want to breakout allover. Just the word test makes me breakout. its horrible. I tried a low dose of NPP by itself 100 mg every 3 rd day I ran this for 12 weeks with absolutely no problem. Had no sex drive issues at all. Arounf the 13 week i felt the slightest sensitivity in nipple so i added an AI ( aromasin @ 12.5 every 3-4 days) took care of that. around week 16 i bumped up to 150 fr the last 4 weeks. At 20 weeks I pyramided down ( Iknow it goes against the norm but the 1st cycyle like this was miserable when I ended & began PCT. The tamper down was about 4-6 weeks going as low as 25mg.. I used HCG a little during middle then more during the last month. I did my PCT with 1 1oo mcg of Triptolelan Not sure of spelling. Had clomid on hand but didn't use. Also some natural test booster on side. I felt the tapper was better then the sudden shock. I liked it i did this 3 times so far. getting ready again, I go from mid to end of may through September- October . I make good solid gains that i would say 75% sustained. Everyone is different. This time I am going to run proviron & see how that feels.. Just my experience. Hope it give you something to think about. YES you become a pin cushion but i move around & use insulin pin for shoulders & other small muscle groups.
