Longer DAA cycle length - useful info from new study

[Greenhulk]

There are only two studies regarding use of DAA in human subjects. The second study however is especially interesting because the duration of supplementation was much longer.

And this may be of interest to all of those who would like to run longer cycles of DAA. In the first study, the supplementation only lasted 12 days, in the second one, it lasted 90 days. After 90 days of supplementation in subfertile men, there were no reported abnormalities noted in serum measurements. So, longer runs of taking DAA appear to be fine.

Does the study show positive benefits of longer cycle lengths?

No, not really. There seems to be quite a variance in how well subjects respond to DAA. Here, they report a 30 to 60% increase in testosterone levels at the end of the treatment. In the first study, they reported a mean increase of 42% (mean of all subjects). So, while you can run longer DAA cycles, I conclude from these results that after around 12 days you will already have reached the maximum increase in test that you will get.
