I like his suspension alot. I mixed in a lidocaine additive from Animal and it is a completely painless shot that goes easily through a 25g, probably even smaller. I heard even without the lidocaine it is a pretty painless shot anyway, less so than any type of prop. The great thing about oil based suspension is you can load it in a 25g pin with some fina, do one shot 2 hours before lifting, and you will get stoked!
BTW this stuff IS NOT underdosed, so do not get tempted to shoot to much of it unless you have a boatload of femara, aromasin or armidex. 500-600mg a week of this stuff feels to me like a gram of any other test (since it hits faster and has no ester taking up space). I blew up last month on 350mg a week of it alone, and even though I was taking 40mg nolva a day still got really bad water retention. When I ran it at 600mg I remember that .5mg armidex barely did the job.
Again, while I know "test is test" I do think you need more anti-estros with this suspension than you would with the same dose of test prop.
