JYM Mass Gainer

Mass JYM Features

Mass JYM Protein Blend

Designed to the exact specifications as my award winning Pro JYM protein – each serving of Mass JYM delivers 30 grams of the highest-quality protein powder blend available. Mass JYM delivers 50% casein from micellar casein and milk protein isolate; 40% whey protein from cold-filtered whey protein isolate and milk protein isolate; and 10% egg white protein.

This protein blend provides just enough fast-digesting whey to quickly spike muscle protein synthesis, plus adequate amounts of slow-digesting casein to keep protein synthesis elevated for several hours after ingestion. Egg white protein provides a medium-digesting protein source that also provides higher levels of sulfur-containing amino acids as compared to dairy protein.*

Mass JYM Carb Blend

Each serving of Mass JYM contains 30 grams of carbohydrates to deliver a 1:1 ratio of protein to carbs. This is critical. Consume too many carbs, and you’ll gain body fat in addition to muscle.* Take in too few carbs, and you won’t optimize muscle growth.*The 1:1 ratio of protein to carbs helps keep the gains lean and steady.*

Mass JYM’s ratio of low-glycemic (low-GI) to high-glycemic (high-GI) carbs is another key aspect that makes this formula a true lean-mass-gainer. I designed the carb blend in Mass JYM mainly from pea starch, isomaltulose, and oat fiber to deliver a 3:1 ratio of low-GI to high-GI carbs.
