Placebo proved ineffective and sildenafil and sildenafil plus ALC and PLC proved effective. The International Index of Erectile Function-15 scores of the group 2 patients were significantly greater than those of group 3 in the following domains: erectile function, sexual intercourse satisfaction, orgasm, and general sexual well-being. The drugs did not significantly modify the score in the sexual desire domain or in the peak systolic velocity or end-diastolic velocity of the cavernosal arteries. Sexual behavior interviews revealed that 2 of 29 in group 1, 28 of 32 in group 2, and 20 of 39 in group 3 attained satisfactory sexual intercourse (P <). Only group 2 had a significantly increased percentage of patients with a positive intracavernous injection test after therapy (% versus %; P <). ALC plus PLC did not significantly improve the side effects of sildenafil.
N-Acetyl Carnitine is simply another name for what is usually marketed as Acetyl L-Carnitine for brain and nerve support. Bear in mind that the abbreviation NAC is also used for N-Acetyl Cysteine , which is a precursor for glutathione synthesis in the body. Sometimes the use of abbreviations in the dietary supplement world can be a little confusing—like ALA used for Alpha Linolenic Acid (an Omega-3 Fatty Acid) and Alpha Lipoic Acid (an antioxidant). You have to be really careful about looking at the context to see what the abbreviation is being used for just to be certain.
