first off i seem to really respond well to syntherol, i was going to follow big a's protocol but i just don't need that much. anyway i put a little over 1" on my bi's with 1 bottle. so last friday i go to shot 3cc in each head of the bi's i never went above 2. so shoot'm up go to the gym, go home eat, then go to work. well i wear a polo shirt at work which has the lining around the end of the sleaves, before i put on noticed how swollen my bi's were but didn't think anything about it. well when i got home that night i have a ring around both bi's right in the middle where the peak should be from the shirt being tight. my bi's looked like 2 camel humps,i had double peaked bi's. i took about 24 hours for them to return to normal.
