i did this the other day and i noticed a MAJOR difference
ive injected insulin dozens of times before, and ive injected b12 dozens of times before...
but this was the first i injected b12 right after insulin
by injecting b12 inner muscularly a few minutes after injecting insulin (10iu's, along with 100g sugar in 2 coke cans) inner muscularly made a HUGE difference
i IMMEDIATELY noticed a DRAMATIC change in my appetite and started eating EVERYTHING in sight (clean foods)... this has never happened to me before
within 20minutes my hunger increased, and before it did i wasnt even interested in eating...
then later on that night i also noticed my libido go up dramatically... like i was on viagra!
not too mention i suddenly noticed an extreme pump which lasted for hours... that hasent happend to that extreme degree before
(i took in 200g protein within an hour and half of doing this, along with 10g of creatine, 10g glutamine and 2g HMB)
for those looking to put on quality mass, or really any quality muscle, i highly recommend trying this
its my suspicion that it will make your muscle fibers more dense and thick, giving a more defined look... but who knows for sure
try it!
