If you’ve spent your whole life being the “skinny guy” no matter how much you eat or train — stop. This breakthrough is helping hardgainers finally pack on real size, without steroids, needles, or crazy side effects.

I’m Dr. Fras, a board-certified functional medicine physician based in Berlin, Germany.
For over 15 years, I’ve worked with men who train consistently, stay disciplined, and push themselves in the gym — but still struggle to gain weight or put on noticeable muscle.
In many cases, the problem isn’t their effort.
It’s their body’s low natural output of growth hormones — and a chronically low appetite that makes it nearly impossible to eat enough to grow.
That’s why I focus on solutions that support the body’s own muscle-building pathways — including appetite regulation and hormonal signaling — without resorting to steroids or extreme protocols.
• Poor appetite
• Slow recovery
• Low energy
• Difficulty gaining muscle
• Slow progress, even with training
I've seen it all.
These aren’t mindset issues. They’re physiological.
And for many, the truth is hard to swallow — because it means what they’ve been told about building muscle is incomplete at best.
The standard advice — just eat more, train harder, and take your whey protein — doesn’t cut it for everyone.
Why Most Muscle Supplements Aren’t Built for Hardgainers
Walk into any supplement store and you’ll see the same promises:
“Mass gainer.” “Extreme size formula.” “Anabolic whey.”
But ask any naturally skinny guy who’s actually used them — and the story’s the same: little to no results.
Here’s why:
Most popular supplements are designed to support muscle growth — not trigger it.
They assume your body already has the right hormonal environment, hunger signals, and recovery capacity.
But if you’re a hardgainer — if you’ve always been underweight or struggled to bulk — your body doesn’t respond the same way.
You’re not just lacking protein or carbs.
You’re lacking the internal signals that tell your body to eat more, build tissue, and retain size.
That’s why the usual go-to’s often fall flat:
• Creatine helps with strength output — but not appetite or mass gain.
• Protein powders add convenience — but don’t trigger growth on their own.
• Mass gainers are just high-calorie shakes — if you’re not hungry, you won’t use them.
• BCAAs and pre-workouts might help performance — but they don’t address why your body won’t grow.
If your body isn’t primed to grow, these won’t move the needle.
What I discovered left me shocked...
What If There Was a Safe, Proven Way to Trigger Real Muscle & Weight Growth — Backed by Science?
Instead of forcing more food down or choking down another “mass gainer,” what if you could activate your body’s own ability to grow?
Modern research has shown that certain compounds — when taken consistently — can stimulate key hormones that control appetite, recovery, and lean muscle development.
No needles. No steroids. No complicated stacks.
This approach doesn’t rely on harsh or dangerous shortcuts. Instead, it supports the natural processes your body already has — just not in high enough amounts to see serious gains.
We’re talking about benefits like:
1. Increased natural growth hormone production, leading to better recovery and deeper sleep
2. Stronger appetite signals, making it easier to eat more and grow
3. Improved muscle retention, so you keep more of what you build
4. No suppression, so your natural testosterone stays intact
This isn’t about hype. It’s about finally giving your body the tools it needs to grow — in a way that feels natural, sustainable, and powerful.
And that’s where Ibutamoren MK677 comes in.
Ibutamoren MK677: The Growth Trigger Your Body’s Been Missing
Ibutamoren MK-677 is not a protein powder or a pre-workout.
It’s a compound that helps your body release more growth hormone — the stuff responsible for size, recovery, and strength.
How does it work?
It copies a hormone in your body called ghrelin — the same one that controls hunger.
When that gets activated, it tells your brain to release more growth hormone and IGF-1 — two key hormones for building muscle and gaining weight.
What makes it different from steroids?
• No testosterone shutdown
• No injections
• No crazy side effects
• You stay natural — but grow faster
It’s simple. If your body doesn’t produce enough growth signals on its own, MK677 helps flip that switch.
What You’ll Notice on MK677 — Week by Week
Week 1 – Hormonal Activation Begins
The first thing most users report is better sleep — longer, deeper, and more restorative.
You may also notice your appetite gradually increasing, and muscles start to feel slightly fuller even without changes in your training.
Week 2–3 – Hunger Kicks In
By now, your appetite ramps up hard — for many, this is the point where eating more no longer feels like a chore.
Workouts feel stronger, recovery is faster, and you’ll likely notice better pumps and improved stamina in the gym.
Week 4 – Muscle Growth Becomes Noticeable
Visible changes in body composition may begin. Lean mass increases, especially when combined with a calorie surplus and consistent resistance training.
Most users report a 2–4 kg gain, driven by a mix of muscle, glycogen storage, and slight water retention.
Recovery is sharp, and sleep remains high quality, improving systemic repair processes.
Week 5–6 – Strength and Size Accelerate
At this stage, it’s common to hear people around you say, “You’re looking bigger.”
Strength is up, you’re hitting heavier weights, and the scale continues to climb. Your muscle fullness stays constant, even on rest days.
Week 7–8 – Locked In
You’re likely at your heaviest, strongest, and most anabolic state yet — with continued progress if nutrition and training are aligned.
Sleep, recovery, hunger, and training output all stay elevated.
Longer-term users report:
1. 4–7 kg of weight gained (largely lean tissue)
2. Noticeable changes in muscle density and roundness
3. Enhanced work capacity and training motivation due to quicker systemic recovery
...But here’s the thing: not every MK-677 product is created equal.
Quality, purity, and bioavailability make all the difference — especially when you’re trusting your body to respond the right way.
That’s why if you’re serious about results, you need a source you can trust.
