I made it at 400 mg/ml with 2/20 and grapeseed. It did fine for about a week. Then it crashed right as I was drawing from the bottle and my tren E solution immediately turned from liquid to the consistency of a bar of soap. I could see the crystals growing, it was strange.
I cut it down to 360 mg/ml and it holds now that it's summer but when it cools down, crystals form. I just heat it every time. A batch of tren I made at 250 (2/20/GSO) also used to crash when it got cool.
Tren e always gives me more injection site soreness than any other thing. I don't know if it's the crystals or if the stuff just irritates me. I always draw a little test or nandrolone with it and that helps a lot. Even prop helps.
Next time I make tren E I will make it at about 360 again. I'd try using a little EO if I thought it would help it hold at 400. I've never heard of somebody using EO with tren E.
For sure I'm going to try tren decanoate once I run through my tren E. I have a feeling that the decanoate estered tren will hold at 400 mg/ml. Anybody try that yet?
