PenaMax – Nutritional Supplement to enhance male performance

ACETYL-L-CARNITINE AND PROPIONYL-L-CARNITINE: • Both acetyl-L-carnitine and propionyl-L-carnitine are natural substances that help boost our energy metabolism by acting as sources of their parent compound, carnitine. • Carnitine in our cells facilitates the transport of fatty acid molecules across the mitochondrial membranes. • Carnitine levels tend to decline with age, so maintaining a healthy supply of this compound provides many health benefits.

CARNITINE VERSUS ANDROGEN ADMINISTRATION IN THE TREATMENT OF SEXUAL DYSFUNCTION, DEPRESSED MOOD, AND FATIGUE ASSOCIATED WITH MALE AGING. Urology. 2004 Απρ., 63(4):641-6.

Randomized, double-blind, placebo-controlled trial investigating the effects of propionyl-L-carnitine and acetyl-L-carnitine, taken together, versus those of testosterone undecanoate. 150 generally healthy men, aged 60–74 (average 64), whose chief complaints were those typical of older men who feel that they’re “slowing down” in various ways.

Following are the categories and the results observed:

Erectile function – Both testosterone and PLC/ALC produced significant improvement at 3 months, with further improvement at 6 months. The improvement with PLC/ALC was significantly better than that with testosterone at both time points.
Satisfaction with sexual intercourse – With both treatments, there was significant improvement at 6 months
Orgasm – There was no improvement with testosterone, but PLC/ALC produced significant improvement at 3 months, with further improvement at 6 months.
Sexual desire – Both treatments produced significant improvement at 3 months, but no further improvement at 6 months
General sexual well-being – There was no improvement with testosterone, but PLC/ALC produced significant improvement at 3 months, with no further improvement at 6 months.
Depression and fatigue – both improved – Both treatment regimens produced significant mood improvement at 3 months, with no further improvement at 6 months. At both time points, the scores for the PLC/ALC group were significantly lower —meaning better mood—than those for the testosterone group.
