ProteinFactory® Weight-Gainer Essentials Stack

The Cleanest, Smartest Way to Gain Size — Without Paying for Sugar

Most mass gainers on the market are nothing more than bags of maltodextrin, disguised as premium products. You end up paying for sugar, fillers, and low-grade protein.

This stack is different.
Created by ProteinFactory®, it uses three clinically proven foundational ingredients for real muscle growth:

• Mega Whey 10 lbs → High-quality whey protein concentrate with exceptional amino acid profile

• Oatmuscle → Whole-food, slow-digesting carbohydrate powder with a low glycemic index

• Creapure® Creatine → The purest, most researched creatine monohydrate in the world

Together, these three essentials support lean weight gain, stronger workouts, better recovery, and consistent caloric surplus without turning your gains into fat.

Why This Stack Beats Commercial Mass Gainers

Commercial mass gainers typically contain:

• Maltodextrin as ingredient #1

• Dextrose or corn syrup solids

• Low-quality, highly processed proteins

• Artificial flavors, sweeteners, and gums

With this stack, you control the quality yourself.
No maltodextrin. No dextrose. No junk.
Only clean calories that actually build muscle.

The Truth About Maltodextrin, Tapioca Starch, and Fat Gain

Mass Gainer Trick #1: “Maltodextrin” = Hidden Sugar

Maltodextrin has a glycemic index of 105–135, meaning it spikes blood sugar faster than table sugar.
This creates:

• Rapid insulin surges

• Increased fat storage

• Energy crashes

• Bloating and water retention

Most mass gainers list maltodextrin as the first ingredient, making their “1,200-calorie serving” nothing more than a bag of glucose disguised as a supplement.

**Mass Gainer Trick #2: “Tapioca Starch” ≠ Clean Carb

(Companies Use This To Fool You)**

A lot of brands switched from “maltodextrin” to “organic tapioca starch” because it sounds healthier.
Here’s the secret:

Tapioca starch is essentially just another fast-digesting, high-GI carb — metabolized almost identically to maltodextrin.
Companies use it to appear “clean” while still giving you a cheap carb that leads to fat gain, not lean mass.

Why Oatmuscle Is Superior

Your Oatmuscle formula is:

✔ Low Glycemic Index (slow digesting)
✔ Whole-food derived
✔ Higher in natural fiber
✔ Much steadier blood glucose impact

This leads to:

• More lean mass gain

• Less body-fat accumulation

• Longer-lasting energy

• Better nutrient partitioning

• No insulin spikes

Clean carbs = cleaner gains.
That’s why the ProteinFactory stack builds actual muscle, not sugar weight.

• Low-quality, highly processed proteins

• Artificial flavors, sweeteners, and gums

With this stack, you control the quality yourself.
No maltodextrin. No tapioca starch. No dextrose. No junk.
Only clean calories that actually build muscle.

PRODUCT FAQ 

FAQ – ProteinFactory® Weight-Gainer Essentials Stack

---

1. What makes this weight-gainer stack different from other mass gainers?

Most mass gainers use cheap maltodextrin or tapioca starch, which act like sugar and cause rapid fat gain. Our stack uses Oatmuscle, a whole-food low-GI carb that supports lean mass—not body fat.

---

2. Will this stack help me gain weight even if I have a fast metabolism?

Yes. This stack provides the three essentials for weight gain: high-quality protein, clean carbohydrates, and pure creatine. Together, they make maintaining a caloric surplus much easier—even for hardgainers.

---

3. Why is Oatmuscle better than maltodextrin or tapioca starch?

Oatmuscle digests slowly, helping maintain stable blood sugar and reducing fat storage.
Maltodextrin and tapioca starch, despite sounding “clean,” are fast-digesting high-GI carbs that spike insulin and promote fat gain.

---

4. Does this stack cause bloating or sugar crashes like commercial mass gainers?

No. Because the carb source is whole-grain Oatmuscle—not sugar-based fillers—users experience steady energy and fewer digestive issues.

---

5. Is creatine included in the stack?

Yes. The stack includes Creapure®, the purest and most clinically researched creatine monohydrate in the world.

---

6. How should I use the stack for best results?

Mega Whey: 1–2 scoops post-workout or between meals
Oatmuscle: Add 1–3 scoops to shakes for clean calories
Creapure: Take 3–5 grams daily

Consistency is key—use daily to maintain a caloric surplus.

---

7. Can I customize the calories?

Absolutely. Since Mega Whey and Oatmuscle are separate powders, you can precision-control your carb-to-protein ratio—something impossible with premixed mass gainers.

---

8. Is this stack suitable for athletes?

Yes. With clean ingredients, steady energy, and premium creatine, the stack supports strength, recovery, and performance without sugar crashes.

---

9. Will this help me gain muscle without adding too much body fat?

Yes. The combination of low-GI Oatmuscle and high-quality whey promotes lean mass rather than bloated sugar weight. It’s engineered for quality gains, not empty calories.

---

10. Are there artificial sweeteners, fillers, or seed oils?

No. The entire stack is free of maltodextrin, dextrose, tapioca starch, artificial sugars, and unnecessary additives.
