..fo course there s fiber destruction..i ve mentioned many times that big amounts of oil damages muscle,lose some strength, and does not stretch any fascia to help it grow..itmight stretch something but definetly wont help much with muscle growth on small muscles, at least oil doesnt, short esters of gear actually helps...
Next time I have a few of my buddies in the area ill ask some to come by my office and ill grab some ultrasound images off the record and snap some pics to post up. MRI's off the record are a little harder to do unless there is a cancellation and we arent double booked already.
Not that it will change anything that people do but i think its interesting to fully understand the effects.
