Let me start with the blue tops, blues are made by a thousand people so hard to say if your is quality and I have not used theres so cant help there. I do have a source here with confirmed kigtropin. At about 100 a kit ehealthpill if that helps. Ok as to all of your questions and I have gone over this extensively here in hgh forum but I'll hit it for you again. First up you should always put up your age and stats along witbh goals because these things are very different for every age group. So let me vo ahead and give you some general guidlines and answers and the n later you can come back with the items needed an d we can tweak to age and goal. Lets assume you are in good shape and young for the general here.....it is better if you could be on hgh at about 2 or 3 iu's ed for a period of time before cycle but not a must if you plan on running future cycles . Upon getting close to cycle one can begin to frontload the cycle with low mg's of prop as you ramp up hgb iu's going into cycle. You could begin 4 weeks before cycle and ramp up 1 iu each week so that by the time the actual cycle begins you are at les say 5iu's and stay there for the duration of the cycle. As the cycle ends you could do a 4 week taper with prop not only acting as a pct, even if you want a jump start at the end,and drop your iu's down each week as you did going into the cycle. This adresses your question about needing test while on hgh. The body has an axis, hpg loop, which includes growth and test. The axis itself will cause the body to discard any hormone it cant balance. So lets say naturally your body produces enougb test as a young person to balance 2 or 3 iu's of growth. What happens if you are not using any test off cycle and pop 5 iu's of growth. The body can balance 2 of that when compared to natural test production a d it will discard the remaining iu's. So the answer to your question is, you do need test at higher iu's but have enough test to balance and utilize smaller iu's in an off cycle mode given you are not 40 ish or above. So we stay around 2 or 3 iu's as a young person off cycle is the short answer...last question was , start now or later. I would wait at least 4 weeks for cycle so you can get it rolling in the system and ramp up a little as you bleed in and front load the cycle and even though you will not benefit from hgh as much this cycle you can run it all the way to next cycle and benefit much more on it....this does not address prop recommendation going in or coming out in terms of dosage but we need the things I asked for to help you specifically. Throw up stats, age and goals and we can go from there on our sust cycle....
