Ok, here goes...
Way back in the day Nutra sold a crystal phen that was phenominal (maybe it was just me being introduced, but I have never seen a thick crystal phen since)
Next, they sold a powder batch that was good, but not as good as the thick crystal batch...needed more powder to get the desired effect...
Next, they sold a super phen which I believe was r isomer which was like a small salt crystal...was almost as good as the thick crystal...
I believe it's back to the powder as of current...which I'm sure is good.
I have never been let down by Nutra's Phen. SNS has never let me down nor has AI Sports capped phen products.
Ok, let's go even further...IBE used to sell neurobalance, a cherry liquid phen...it was REALLY good.
I have tried Primaforce capsules way back and it worked, I just didn't like 250mg in a cap.
