Animal M-Stak by Universal Nutrition
What is Animal M-Stak? A natural, non-hormonal supplement designed for the most stubborn of all 'hardgainers.' From green beginner to diehard vet, we’ve all gone through it – skidding to a halt, our progress idles on a plateau. Can’t gain another pound, workouts are stale, lifts are static. This is the hardgainer’s syndrome, and from the most slender of ectomorphs to the most muscular endomorph, we’ve all been there. Desperate to ignite new growth, we’ll try almost anything.
