I would strongly recommend tren ace for your first tren cycle. I've ran both. IMO the sides are worse on ace, but everyone reacts differently. My roommate took tren e and was absolutely nuts for a month. Couldn't sleep, higher than normal aggression, sweated like a pig all the time. Easier to get off ace. ED injections aren't bad if you get 25g pins. I'm about a week and a half into my cycle pinning ed with 22g pins waiting on my 25g and I feel like a pin cushion. Anyways 300mg/week would be fine for your first time. I like your pct, works like a charm for me every time.
