Why is a signature and proof of age required for this product and not others?
New York law imposes the requirements for certain dietary supplements making “weight loss” or "muscle building" claims. Only those products making these claims require a signature and age verification upon delivery. For states with these mandates, products will also be charged an additional fee. This fee covers additional order handling costs and will be shown in your cart at checkout. LEARN MORE
