Damn you have a great memory JD!
Now that you mention it I remember that too, and if it is only 1 bottle then that's a definitive no imo. I understand having a plan, and sticking to it, but I have no issue with thinking outside the box either. If you are experienced and in tune with your body, and want to experiment I'd be a hypocrite to say no. However like I said above this needs to be done with orals or short esters in case a quick bail is needed.
For example I was running a test/eq/proviron cycle a few years back at pretty high dosages of both compounds. It was a 20 week cycle and at week 14 I decided to throw in a moderate dose of tren a. The cycle was going great, but my reasons were twofold. First it was to see how the tren would enhance the current cycle, and second was to see how I responded to tren with high test. The first few weeks were great, but then I started having elevated e2 issues that no matter what I couldn't get under control. I ended up bailing on the tren which was easy because it was short estered. Had it been tren e I would've suffered for two additional weeks. The moral of the story here is that I learned me, tren, and high test don't mix and that there was no harm no foul since tren a was used.
