TweetI am running Tren A for twelve weeks and at your dose 12 weeks is fine if you can handle the sides...I PREFER to run it that long to get the full synergistic effect of the compound. I feel 8 weeks and this is my opinion is to short to run it. You will get good gains but I prefer 10-12 weeks. Now when people run 100mg ed then its trouble but 75 eod is fine for twelve weeks. If you do cut it short then throw that winny in for 4 weeks to harden up, that is an option too.
