No, but it is really weird I was taking a test cyp, tren 75, test prop cycle for about 16 weeks and for all of those sixteen weeks when I ran my calves felt like they were going to explode and it was hard to put the pressure on my feet..i mean excrutiating pain...felt like i had no calfs, they almost went numb...but only when i ran...I do not inject in my calfs but since ive been off my cycle for about a week and a half the pain is gone when i run...but i was wondering for future references what gear wont cause this....Ive heard of this happening to many people.
