I don't yet know which is causing it, but either high BB content (15-20%) or EO is causing me major problems.
I made Tren E with EO and it crashed. (It may also be crashing in depot as well.)
I also made a Test Prop (200mg/ml) with EO.
I recently made and started using a Test E (500) made with EO/grapeseed oil.
All three were made with high BB and EO.
The problem...every time and every site where I shoot these solutions produces a hardened lump that prettymuch cripples the muscle site. This last week, I shot the Test E and Tren E into my pecs and for the last six days, I looked and felt like I just had pec implant surgery! I don't remember it being this bad when I used the Test Prop/EO solution, but I am having major reactions with the enanthate-estered hormones.
I also made some Bold Cyp with EO, though I have not tested it yet.
Just something to take note of for all the lay-chemist out there...
