I was reading with excitement the ingredient label on PNI's "Paragon" NMDA product until I kicked up the anti-estrogens in it. For me, that's a red light.

Almost any product that touts it's anti-estrogen properties completely crushes me. I will have no libido, I become a raging dickhead and my joints will hurt.

The Sustain Alpha gel I can get away with two pumps max. I've been doing one pump lately and getting benefit. Much more than that and my estrogen suffers.

Anyone else out there experience similar effects?
