just finished my third cycle of m1t,added n02 to the stack i was doing for the last 11 days ,the results were none exsistant.there were no mind blowing pumps especially ones that lasted for hours afterword. any results i did see were from the m1t which included strenth gain as well as weight gain.although my muscles were tight and hard that was always the case while using m1t,that was my reasoning for adding the n02 i thought this would inhance the results....wrong!!!! i am totally sold on m1t the results are always awsome but beleive me ive done m1t long enough now that if no2 had something to offer i would have noticed.in canada it costs anywhere from $80. up. i will finish the bottle and let you no if it helped in regard to saving any gains.for now save your money and stick to creatine and glutimine...
