Contact / Disclaimer

Legal notice in accordance with § 6 of the German Teledienstegesetz (Teleservices Act), in the version promulgated on 20.12.01, which provides the legal framework for electronic commerce.




1. Content of the website

The author does not provide any guarantee whatsoever for the topicality, correctness, completeness or quality of the information provided. Liability claims against the author which are based on damage of a material or non-material nature and which result from the use or non-use of the provided information or, respectively, by the use of incorrect or incomplete information are generally excluded insofar as there is no demonstrable fault of an intentional or grossly negligent nature on the part of the author. All offers are subject to confirmation and are not binding. The author expressly reserves the right to modify, append, delete parts or the complete online content without prior notice, or to cancel the publication temporarily or permanently.

2. References and links

In the case of direct or indirect references to third-party websites (hyperlinks), which are outside the author's sphere of responsibility, an obligation to assume liability would take effect exclusively in the case of the author having knowledge of the content, and it having been technically feasible and reasonable for him to have prevented its use should it have unlawful contents. The author herewith explicitly declares that the respectively linked pages were free of illegal contents at the time the links were generated. The author has no influence of any kind on the current and future creative design, contents or copyright of the linked pages. He therefore explicitly disassociates himself herewith from all content of any linked pages that have been changed after the links were generated. This statement is valid for all the links and references contained within the scope of the author's own internet offer and also for entries by third persons in the guest books, discussion forums and mailing lists set up by the author. Liability for any illegal, incorrect or incomplete content and, in particular, for any damages arising from the use or non-use of information offered on linked pages lies solely with the provider of the linked or hyperlinked page, and not with the author who only referred the user to the particular page through a link.

3. Copyright and trademark rights

The author has made every effort in all publications to comply with copyrights for the used images, audio documents, video sequences and texts and has strived to use images, audio documents, video sequences and texts created by himself or to use images, audio documents, video sequences and texts that are license-free. All trademarks and brand names mentioned on the website and, where applicable, copyrighted by third parties, are unreservedly subject to the provisions of the respectively applicable trademark law and to the ownership rights of the respectively registered owners. It cannot be assumed that trademarks are not protected by third parties simply because this is not explicitly stated. The copyright for any published items produced by the author himself shall remain solely with the author of these pages. Duplication or utilisation of such images, audio documents, video sequences and texts in other electronic or printed publications is not permitted without the author's explicit consent.

4. Data protection

Insofar as this website contains options to enter personal or business data (e-mail addresses, names, addresses), the disclosure of this data by the user is carried out on a purely voluntary basis. Insofar as is technically possible and reasonable, the use and payment of all offered services are also permitted without providing any personal data or by submitting anonymous data or using an alias. Contact information published within the scope of the disclaimer or similar information, such as postal and email addresses as well as telephone and fax numbers, shall not be used by third parties for the transmission of information that has not been expressly requested. The author expressly reserves the right to take legal steps against senders of so-called spam emails if the above stipulation is infringed.

5. Legal validity of this disclaimer

This disclaimer is to be regarded as part of the website from which reference to this page was made. Insofar as parts or individual formulations of this text are not, are no longer or are not fully in compliance with the current legislation, this shall not affect the content and validity of the remaining parts of the document.

Dear reader,

We are often asked for amino acid product recommendations. As we generally cannot answer this in a universal way, the information collected from our German colleagues could be used as a guide to those who are looking for quality supplements: The site trialed and evaluated the products and services of the main providers in German-speaking countries. The information is currently only available in German, but you will nevertheless be able to see the names of the best manufacturers.

    Arginine and zinc make sperm cells more resilient

    “Men should ensure that they consume a balanced diet and get enough exercise” explained Professor Frank Sommer from the Institute for Men’s Health, at the Hamburg-Eppendorf Clinic in Germany. He specifically recommended arginine when presenting his nutritional advice, as the amino acid can have a positive effect on the dynamics and fitness of sperm cells. The trace element zinc also contributes to the resilience of these cells.
