Adding test would be a good idea - maybe some prop (just mix the tren and prop together in one injection EOD) or if you want longer acting try Test-E taking a shot every 3-4 days.
What is the length of your cycle? What are your goals with this cycle?
Many wouldn't reccomend taking the tren more than 6 weeks but personally I would run it for up to 10-12 weeks with no problems. I love tren and add it in most cycles - currently doing a shorter 5 week cycle with tren + others.
What about you PCT - no point doing a cycle if you not goint to follow PCT to keep your gains.
I would also consider using proviron during the cycle. Also after reading AR article on stan I've added 20mg Stan tabs to give it a try as I'm on a high test base.
My length of my cycle is based on health recommendations, I plan to take an on-off approach for about a year or two. I see things that read to go on for like 8 to 12 weeks for some gear and then off for about the same time.
What is the PCT that you asked me about? Not familiar with abbreviations, I don't chat much. I work in I.T. so I like to stay away from a PC as much as possible, so that I can have a life.
Do you mean my (Post Cycle Training) regimen? If so I plan on doing the same amount of work as when I was on them, just much less weight of course.
However, I am interested in your comment about the ability to "keep my gains" also could you elaborate more about the estrogenic bloating?
