I gave the test booster a go earlier this year to see if it had noticeable effects. It probably took 2 weeks of daily use to feel anything. And even then, it was pretty mild. I would say the biggest effect I felt was it being an anti depressant. For no reason you feel upbeat and positive about everything. The test booster I used was also an estrogen blocker, which probably is the most important part of it.
Either way, best case scenario it will boost test levels by 30-40%. Where AAS will boost it by 4000%. The effects will be more noticeable for people with low test levels. It's kind of like a multivitamin, where it fills in any deficiencies.
In a month I might try a different brand that's D-Aspartic Acid based to see if it works differently.
