It’s not pharmaceutical, but it is synthetic. I will be switching to TM as @Bulk Reef Supply ticked me enough off. I am a man of principal.I
I agree with you. Is HW pharmaceutical grade? That's what got me with TM. I have a medical background, so I know how difficult it can be to achieve "pharmaceutical grade". I wouldn't steer you wrong... maybe give TM a shot. It was so worth it in my opinion.
