I've never had any problems with tren e crashing... My lab rats use 1.5% BA, 20% BB with cottonseed carrier oil... Tren blend 300(200 enanth/100ace). Holds well ar 2%/20%(most blends do tend to hold better, with lower solvent levels!... A high potency blend, such as tren 300, makes it nice and easy to get all the oil into you, without being a human pincushion!
Any questions, feel free to ask... In post, or pm
