What Our Clients Say
"I had the pleasure and good fortune to have a private phone consultation with the famous and extremely well informed Agingdoc- real name David Barzilai MD, PHD. It’s virtually impossible to find a medical doctor well versed in all things health and life extension related, and certainly you won’t find one as informed as David.
He has vast knowledge of the medical literature, second to none, and this is clear if you’ve ever visited his Twitter site, agingdoc1, where, on a daily basis, he posts numerous up to date studies in the longevity field.
I found David to be refreshingly humble, engaging, and incredibly informed."
