no i havent done the blue tops but many of my buddies have in doses anywhere from 2 to 10iu per day. Got various feedback on the quality of it. Not one said wow it was great. Why i do it in the evening is because of what i researched, and the conclusion i came too from what i read was that a dose prior to bed is more effective for fat loss. this is an experiement for me, i have never used GH before, i am 34 and have been on and off gear since i was 20. I wanted to try something new and see what it would do to my body, possibly heal old injuries, lean right out etc etc.. and of course the healing properties it has to the organs etc. ive been on it now since sept 1st, and no i havent had any numbness or anything but my wrists are starting to get sore. I am doing 4iu per day prior to bed 7 days a week. i have enough for 8 months and if i like it and keep getting the results im after i will continue for a year.i am currently also using test prop and a test 400 blend.. 1cc prop 3x week with .5 cc 400 in the same shot 3 x per week. as of now i am def getting leaner, i havent changed nothing as far as workouts go or diet, i actually cut cardio right out 3 weeks ago to see if it was really as effective as some say with regards to fat loss. im really pleased with the results thus far, and again its only been 27 days.. im not bullshitting when i say i have noticed it either i know my body very well, and i know that just by looking at my abdominal area shits dissapearing almost daily. and trust me i can get fat pretty quick if im not on top of diet and training just the way my metabolism is, its very slow.. i know alot of buddies started getting numbness about 6 weeks in , i havent experienced this yet but if i do ill gladly pass that info on..
