Funny, I've been meaning to post on that thread...In short, it works great!
To try it out, I finished up a bottle of Masteron Prop Sub Q ED, no problems, then moved into the Tren Ace. It's been great, no cough, not sweating much and things are going as you'd expect in the gym...really well. I put not coughing down to having not much vascular tissue in the Sub Q fat. Also, no swelling or soreness.
I'm lean-ish ATM, so my biggest fat deposit sits right above my ass. That's where I inject. Top of the glutes, or low lower-back. If you're lean, I wouldn't go sub q anywhere near the abs. I did before and had a bubble sitting there for a week right under the skin.
This has been good for pinning Prop or Ace ED or EOD. I was getting damned tired of the big assed needles EOD.
Now, all the above stated, I'm a moderate user and I respond well to AAS, Tren is no different...So my doses are small-moderate. .50 for Masteron and .3 ED for Tren Ace. I may go to.5ml for Tren Ace later. It ads up. At .5ml that's still 350mg of Tren a week. More than enough for this kid.
I haven't tried big doses, so can't say Sub Q would work if you're pinning 3ml a day or some-such...
