It’s definitely a question as to what constitutes a worhtwhile gain. Obviously, if you’re feeling measurably better and you can reasonably narrow it down to something like a test booster, then cost issues aside it would likely be worth it.
In my own case, I still need to have one more test run (to filter out the effects of finasteride) before I can say anything for sure about the test booster I took. But even WITH the fina, I only experienced about a 20% increase in Free T, and it came at the expense of a similar increase in estradiol.
So I’m thinking: not worth it.
