years ago i ran my Gh eod so i could stretch it out longer because of financial reasons. ed seems much more effective, but they're other issues to consider. Back then when i did eod, due to cash flow reasons i couldn't run as much and nor did i do slin and thyroid chemicals. So now ed is much more effective for me with of course slin and T4. So it really isn't a fair assessment. Another thing i've noticed over the years, when i ran saizen, humatrope, and jins back then, i got amazing growth/mass/density. Today, with the blue tops and hygetropins, it seems to really effect my conditioning alot more than packing on mass. I now, the thyroid drugs are amazing. Getting back to your question, i really believe in steady even levels, to me taking days off are only beneficial to stretching out your kits.
