Here is a write up summarizing my last cycle of it:

1-14 400mg/wk Test C
1-14 500mg/wk 1-test C
HGH 4iu/day
4-14 Arimidex .25mg/E3D

That cycle sold me on 1-test. My primary goal with that cycle was a recomp and it worked perfectly. I exploded and put inches on everywhere. My shoulders gained 2in, 1in on biceps, 3in around chest/back and lost ½ in around waist. By the end of the cycle I had gained a solid 9lbs and dropped 3% BF. I say a solid 9 lbs because I retained all of it after PCT, including most of the inches, so it was good lean mass and not all water weight. The vascularity and strength gains were pretty insane. The vascularity effects I received from it lead me to believe that this would be an excellent pre-contest compound. My biceps looked like I had fire hoses running through them and I had spider web veins spreading across my chest and shoulders. All of this was noticeable with a BF of 9-10%. I can only imagine the results at 4-5% BF. Towards the end of my cycle when my BF was the lowest, I also noticed that more dense, hard, and grainy look to my muscles. Once again I can only imagine how that would have looked on stage at 4%, but I was still impressed how it gave that hard polished looked at 9%BF.

I noticed no negative side effects from it. I had tons of energy, libido great, no mood swings and didn’t experience any insomnia. Alpha feeling all the way. The one thing that I did notice was that I still had to keep up with my AI, a little bit more than what I needed for a test only cycle at 500mg/wk. 1-test supposedly doesn’t aromatize to any appreciable degree so my increased use of AI has me somewhat perplexed. I am just speculating here, but this could be due to the fact that 1-test has a much greater affinity for the receptors than the test which may be leaving more test left over to aromatize.

I should also mention I experienced no pip from this compound. I had two different brands during my run and both were smooth. Many people seem to shy away from this compound because they hear of these pip horror stories from it. I should mention that if you are allergic to EO, guiaicol, and all that stuff then this is not a compound for you. This is one of the hardest compounds to keep in solution and some hefty amounts of solvents are present in it. These compounds are probably what is causing pip if people are allergic to them and not the compound itself.

As far as dosing with this compound, I see no need to go above 500mg. This stuff is strong and the results are dramatic. It is supposedly 5x more anabolic than test and I believe that to be true. The test only cycle I ran fails in comparison with the addition of the 1-test and I was running less test during this cycle.
I also think that a cycle longer than 14 wks with this stuff is probably unnecessary. The gains really seemed to taper off approaching that 14 wk mark so I think the receptors were pretty saturated by that point and there was no point to continue.

I think 1-test is a very versatile compound and as always your diet will dictate the results. I really think it would particularly shine as a cutter since it doesn't seem to aromatize to any appreciable degree and it really seems to bring out awesome vascularity as well as polishing the muscles with that hard, grainy and dense look. My next contest prep is likely going to include 1-test with either mast or var and very low test.

yeah gets you hard as shit and strong too! very vascular and i could tell it i was very anabolic on it too.

My buddy and I both like the compound immensely...incredibly vascular, dry, hard results like a EQ times 2 or as most people say a watered down tren with not near the nasty sides. The negatives are a pretty good pip and he and I both felt sluggish or kinda test fluish damn near the whole cycle and we've both run it twice. It could be that GP uses EO bc there was a bit less pip than CENSOREDs from way back...that could be the cause of the test flu. All in all if your a person with great discipline in the gym it's great, but your not gonna feel the hulk smash want to lift everything feel like you would hope.
