Rule 1 Mass Gainers Prices

The Rule 1 mass gainers products we track average $44.99; the category as a whole averages $53.79, so the brand is about 16% cheaper than average. An average alone isn't a complete measure: package sizes differ, so the cost per serving gives a more accurate comparison.

We currently track 1 mass gainers products from Rule 1 and record each price four times a day. When the brand removes a product from its catalog we stop listing it, but we keep the price history it built up.

We don't see a verified price drop in this category right now. That doesn't mean the brand never runs sales, only that no real drop has formed in the price history we collect yet. Add products to your watchlist to hear when the price falls.

We collect prices from the store's own site four times a day, and every product card shows when it was last checked. The final price is the one at the store's checkout, where shipping, promotion terms or cart discounts can change the details.
