ProArgi-9+ and the Physicians’ Desk Reference


Since 1947, medical specialists across the world have turned to the Physicians’ Desk Reference (PDR) as the authoritative source of information on drugs and prescribed substances. Synergy is pleased to note that ProArgi-9+ has been featured in the PDR, starting with the 2014 edition, as this expands the possibilities for people to discover the tremendous benefits of our flagship product.

Found in virtually every physician’s office, pharmacy, clinic and library, no medical reference is more current, more recognized, or more respected. Convenient digital versions of the PDR have also been recently made available. Both the physical and digital versions contain ProArgi-9+ label information, dosage instructions, images and more. We are confident that this will encourage more patients, medical professionals and students to discover and share ProArgi-9+ for its great value in supporting a healthy lifestyle.
