I am currently in week 7 of my 9 week winny only cycle... I did IP Winny orals... 50 mg ED... and I started feeling it at the end of week 4... which I thought was kind of late, maybe due to the fact that it was IP, but after that my strength SHOT thru the roof... I started getting veiny as shit and had awesome pumps... this is my first cycle and i love it. The first thing i started noticing after week 1 or 2 was my muscles would cramp a little bit after workout... but now they dont cramp at all which is odd... but now I am having slight joint pain, but not terrible... Just make sure you drink lots of water, 2 gallons if possible... and I would go on glucosomine just to be safe because during workouts sometimes my left shoulder cant take it and i wish I would have taken glucosomine as a precaution... it is too late now, I might get some for post cycle, but I heard it takes a week or so to kick in. Hope this answered your question a little bit...
