Smart Powders Vs Profrontal

I have been taking profrontal for a couple months now and i noticed it will consistently work after about a month of taking it. My problem is i can only take about half of the 2 gram dosage due to it being so expensive. I noticed the smart powders sarcosine is only 15 dollars compared to the 50 dollar profrontal. Any know if the smart powders sarcosine is safe and effective? Thanks!

I looked online and supposedly Sarcosine is one the two things in Profrontal so I guess if you’ve been taking Profrontal without side effects then Sarcosine should be safe.
