The Truth About Mass Gainers
Most mass gainers make you fat, not big. Here’s how to choose one that actually helps you build lean, clean muscle.
Hi again guys,
Food should always be the foundation of a successful bulk. Real meals, real digestion, real nutrients — that’s the backbone of sustainable weight gain.
But the moment someone decides to start a bulk, what do they do?
They run straight to mass gainers.
So let’s break them down properly — what they are, why they seem helpful, why most of them fail, and how to actually use them effectively.
💥 What Are Mass Gainers?
Mass gainers are some of the most popular supplements for putting on weight. Think of them as hyper-caloric protein shakes — usually a blend of:
whey protein
fast-absorbing carbs
cheap oils or fats
artificial flavors
thickeners and fillers
It would not be an exaggeration to say that 90% of mass gainers on the market are trash.
They’re high-calorie, yes — but usually in the worst possible way.
And while making your own is ideal, what if you didn’t have to?
Let’s first understand the “why.”
🧠 Why Do People Use Mass Gainers?
A few reasons come up over and over:
Liquid calories are easier to consume
They’re fast to prepare
Easy to drink on the go
They create a psychological “I’m bulking” feeling
They help people hit a calorie surplus
Do they work?
Yes — if “work” simply means gaining weight.
But weight ≠ muscle.
Most commercial gainers push you into a sloppy surplus, leading to:
excess fat gain
blood sugar issues
poor digestion
inflammation
worse training performance
So yes, they work — but not cleanly, not intelligently, and not sustainably.
❌ What Most People Get Wrong
The biggest mistake?
Using mass gainers at the wrong time.
People drink them:
for breakfast
as a random snack
before bed
during work breaks
All of these are pointless. They spike calories when you don’t need them and encourage fat storage.
✅ When mass gainers actually matter:
Peri-workout.
This includes:
Pre-workout:
If you haven’t eaten in the last 2–3 hoursPost-workout:
When glycogen is low and cortisol is highIntra-workout:
If you’ve already mastered pre and post nutrition
During these windows, your body is primed to:
shuttle carbs into muscle
spike insulin at the right time
drop cortisol
accelerate recovery
build lean mass instead of fat
Outside of these windows?
They’re just sugar bombs.
🔍 What to Look For in a Mass Gainer
With hundreds on the market, people usually pick:
the most popular
the highest calorie
or the best tasting one
In reality, those are typically the worst.
Example of a problematic one:
Serious Mass by Optimum Nutrition

254 g carbs
1000+ calories
50 g protein
artificial flavors + sweeteners
Unless you train like a bricklayer and burn calories all day, this is a fat gainer, not a mass gainer.
⭐ What I Recommend Instead
TRUE Nutrition — Post Workout Blend
This is what a mass gainer should look like.

Why it works:
Clean ingredients
High-quality protein
Optimal carb:protein ratio
Creatine included
Easy to digest
Designed specifically for peri-workout
Macros per serving:
28.6 g protein
33.5 g carbs
2.5 g creatine
Do one serving pre-workout, one post-workout, and you’re set.
Mix with skim milk or filtered water to keep fats under 1 g and digestion smooth.
This is a clean gainer — not an insulin rollercoaster.
