As an example of the first viewpoint, a 2004 review in Trends in Biotechnology written by Leigh Turner of the Institute for Advanced Study in Princeton, New Jersey stated that the products promoted by the A4M have "no credible scientific basis" and that "there are no proven, scientifically established ‘anti-aging’ medications".
作为第一种观点的例子，2004年在《生物技术趋势》上，新泽西州普林斯顿高级研究所的Leigh Turner的一篇综述写道，A4M推广的产品“没有可靠的科学基础”，而且“没有任何已证明的、在科学上确定的‘抗衰老’药物”。
