Frequently Asked Questions
Is shipping free on one-time orders?
Yes, on orders above $75. Subscription orders ship free under the current offer, so a subscription can make sense for products you already buy regularly.
How do I make a guarantee claim?
Call 1-800-705-5226 or email the company within 60 days of purchase, with where and when you bought the product. If approved, you mail it back with proof of purchase, at your own postage cost.
What does the 60-day satisfaction guarantee cover?
It covers Optimum Nutrition products bought from optimumnutrition.com or an authorized online seller, with a refund or replacement. It applies only to the original purchaser.
Does the guarantee apply to Amazon purchases?
Only if the seller is authorized. The guarantee does not cover products from unauthorized sellers, and Optimum Nutrition requires approval before anyone sells its products in an Amazon storefront.
