I feel they are underdosed. I have been taking them for months now (not every day). I was using pharm grade at first then went with his own pressed tabs so I have a reference of what is real.
If I were to guess, a "100mg" tab is probably only 50-75mg based on my "feelings" alone. However, I am very aware of and sensitive to stimulants in my body due to previous bad habits.
With that being said, I would buy them again as they are DIRT cheap and easy to double dose of needed.
I feel the same way about his Tadalafil as well. Underdosed, but so cheap it is still worth it to me.
Plan your dose accordingly noobs who are new to these drugs. They have a LONG half-life so don't simply assume your dose is underdosed without testing a normal dose first!
