Rule 1
Rule 1 Mass Gainer - Chocolate 12lb
What it is
It is a good choice for building size while keeping things leaner. This 12lb tub in Chocolate provides about 15 servings.
Chocolate is the everyday pick and hides well in milk; the 12lb tub is roughly fifteen servings, so it suits a committed bulk.
Who it's for
Lifters chasing lean size — decent appetite, training hard, wanting a controlled surplus rather than the biggest calorie number on the shelf. Also a sensible step up from plain whey.
How to use it
Rule 1 Mass Gainer is a higher-protein, cleaner weight gainer delivering around 740 calories and a generous 53g of protein per serving with quality carbohydrates, to support lean mass gains without excess sugar. Blend with water or milk between meals or after training.
Worth knowing
Contains milk, so it is out if dairy does not agree with you. It is still a surplus product — if you are trying to lean down, a straight whey is the better buy.
Our take
We steer people here when they want to add size without a sugar hit: about 740 calories a serving rather than the 1,250 in Serious Mass, but more protein per serving — 53g against 50g. It suits lifters already eating reasonably who just need topping up. If you genuinely cannot gain at all, the bigger ON tub works harder.
