Know what you're saying about it barely kicking in, Andy, but ultimately you must still get the same effect, just delayed by a week or two. It will then last a week or two longer once it has kicked in.

I use tren ace and I'm more than happy with a 4 week run. I'm also convinced it's still doing its magic for a week or two after I stop. The same must surely apply to tren E, except that the effects will continue for even longer. Depends what you want from a cycle, I suppose.

Do agree that I would wait until I've got enough of everything to run at least 12 weeks though.

It's an awkward stock of AAS to plan an 8 week cycle for though. The OP has used before, just not tren, so I was presuming he knows about PCT etc
