How long is too long??

I have a script for Cypionate, been using 400-500mgs for 8 weeks at a time then back to 150mgs per week for 8 weeks.(for 18 months) My test levels were "27" before I started, hence the script. I feel my body is "tired" of cyp. I dont' get any stength gains or much weight gain. I'm gonna do Tren starting in Oct and get away from Cyp for a while. Any input would be greatly appreciated. What is the going street rate for American Cyp??

You still want to run test with tren. Tren shuts you down big time.

I'm already shut down. Norm test levels are 250-850 I was at 27. A 7 yr old has more test than me. I was gonna use tren alone, but if I'll get better gains w/ both, then great. I don't want to blow up to 250lbs, I'm at 210 at 7-8% bf. Any more weight is a problem for MtnBike racing. I want to get a little more vascular, and harder. Again thanks for the in put.

You would get better gains with both. Without taking test with tren there's a good chance you wont be getting a hard on anytime soon to be blunt.

OOOOOOHH, uh NOT GOOD.

What about Dbol w/ tren. I just feel that my Cyp receptors are full?

That's one of the main reasons to always take test with tren and other gear like deca that shuts you down hard.
