The Hardness Factor 4-Day Insurance Policy	Home / Partners of The Hardness Factor   Prelox THE PENIS VITAMIN Supplement: PYCNOGENOL + L/arginine (Trade Name: Prelox, Pycnogenol Plus) This combination of Pycnogenol (pronounced pick-nah-geh-nall), a patented complex mix of more than three-dozen different antioxidants extracted from the bark of the French pine tree, Pinus maritime, and L-arginine, an amino acid, will directly impact the endothelium, the lining of the blood vessels, shielding them and allowing for better nitric oxide utilization. The end result is a rock-hard erection. The Pycnogenol/L-arginine Program Take 80 mg of Pycnogenol and one gram of L-arginine. On day 3, I want you to increase your dosage to two grams, going to the full three-gram dosage on Day 7. For those taking Prelox Blue, take two capsules daily.
