I use maca especially in the cold winter months. It helps to give me a little boost. It gives me more energy and desire. Together with arginine, it's a great product for active men. I can definitely recommend the brand, as I use several of their products.

The product is great quality and so much better to take than the maca powder. I would order again and again. Fast delivery and very good packaging. Great value for money.

My first impression is very positive, since I have been taking these capsules regularly I have not been ill once. :) Together with a healthy diet and exercise, the product is a great supplement!

L-arginine Most of what you read here about L-arginine ? the natural form of this amino acid ? was completely unknown a decade ago. It was known that arginine favours the wound healing process and the regeneration of tissue, especially in burns, and also ? by stimulating the release of growth hormones ? promotes muscle building and increased fat loss. The immune-strengthening effect of this amino acid (through the increased formation of new natural killer cells) was described in 1991, and its support of the thymus gland, which is crucial for the body's own defence reaction, was confirmed in 1991. The inhibition of the growth of tumours and cancer cells by arginine was reported in 1994. Then the nutrient researchers discovered that arginine plays a decisive role in the production of nitric oxide (NO). This extremely important regulatory substance, which is found in blood vessels and in the brain, has a control function in the production of white blood cells, the expansion (dilation) of blood vessels and neurone transmission in the brain. Orthomolecularly orientated doctors have been using arginine with great success for circulatory disorders of the circulation and heart (e.g. coronary vessels) and to strengthen the heart muscle in cases of cardiac insufficiency. According to reports from Japan and Greece, cardiologists there administer 20???30 g of arginine by infusion directly into the heart vessels of angina pectoris patients and thus achieve a dramatic improvement in blood flow. Thanks to its ability to stimulate the body's own nitric oxide production, L-arginine has now become a valuable natural aid for cardiovascular diseases. Nitric oxide is also needed to increase or maintain a man's sexual performance. This is why arginine is often recommended by orthomolecular physicians for erectile dysfunction. In most cases, these have physiological causes and among these causes, circulatory disorders are in first place.

I bought this product to supplement my diet as I am sure that I am still missing some nutrients. The ingredients are well selected and there are no unnecessary substances in it that I don't need. The pack is big enough to last 2 months so for now I'm happy with it.
