I'm a nobody but that's the best advice you're going to get.you can go with tren e but you need to dial the dose back on it especially considering you had to cut it short with just 300 mg... keep in mind that tren is certainly not for everyone and my thoughts on it are the best way to run it is to not run it at all!
Leave that shit for the pros or the professional idiots (like me).
No offense to anyone.
