Massabulk Starter Stack (MK-677 + RAD-140)

Do you want to start with a powerful, but manageable stack?

The Mass Bulk Starter Stack from Apex Receptor is specially formulated for athletes who are taking their first steps in the world of performance enhancement. This package combines two of the most proven research chemicals on the market: MK-677 (Ibutamoren) and RAD-140 (Testolone).

No injections. No complicated protocols. Just a clean, dual-compound package that you get right away.

Many beginners make the mistake of combining too many products right away.

This leads to confusion, unnecessary costs and a lack of insight into what each component does. The Mass Bulk Starter Stack keeps it simple. Two products. Two clear features. One clear goal: mass.

MK-677 and RAD-140 operate through completely different mechanisms. That makes them ideal for stacking together. You get the benefits of both worlds without the effects overlapping or counteracting each other.

MK-677, also known as Ibutamoren, is not a SARM in the traditional sense. It is a growth hormone secretagogue.

What does that mean in concrete terms? MK-677 stimulates your body to produce more growth hormone and IGF-1. This happens naturally, via the ghrelin receptor. So your body produces more of the hormone responsible for recovery, fat burning and — crucially — muscle mass.

The advantage of MK-677 is its 24-hour operation. You take it once a day and it remains active while you sleep. Recovery improves. Sleep quality goes up. And the anabolic environment in your body remains constantly elevated.

For a starter, that is worth its weight in gold. You don’t have to take peaks and troughs into account. Just consistent, stable support.

RAD-140 (Testolone) is one of the most powerful SARMs available today. Originally developed as a safer alternative to testosterone therapy, RAD-140 has quickly established itself as a favorite among bodybuilders and strength athletes.

Why? Because it’s extremely anabolic without the androgenic side effects you see with traditional steroids.

RAD-140 selectively binds to androgen receptors in muscle and bone tissue. That means: more muscle mass, more strength, better bone density — without the strain on organs like the liver or prostate.

For a starter, RAD-140 is the ideal compound to start with. You feel the effects quickly. Strength goes up in the gym. Muscles become fuller and harder. And because it’s taken orally, there’s no hassle with needles or injection schedules.

The magic of this stack is in the combination.

RAD-140 provides the direct anabolic drive. It forces your body to build muscle mass via androgen receptor activation. MK-677 supports this process from a different angle. It increases growth hormone and IGF-1, which further stimulates protein synthesis and speeds up recovery.

Together, they create a double anabolic attack. RAD-140 builds. MK-677 recovers and grows. The result is a stack that yields more than the sum of its parts.

That’s exactly why this combination is so popular with first-time buyers. You get maximum results with minimal product. No unnecessary additives. No messy stacks of five or six components. Just two high-quality connections that complement each other perfectly.

In a market that is flooded with underdosed, contaminated or even fake products, Apex Receptor makes the difference.

Apex Receptor produces only research-grade SARMs and research chemicals. Each batch is checked for purity and consistency. The dosage per capsule is exact and uniform. No guesswork. No variation from one bottle to another.

When you invest in your body, you invest in quality. Cheap alternatives from dubious sources can not only be ineffective, but also contain harmful contaminants. With Apex Receptor, you know what you’re getting. And that’s exactly what the label says.

One of the biggest barriers for first-time buyers is the fear of injections.

This stack completely eliminates that problem. Both MK-677 and RAD-140 are taken orally. Capsules. Water. Done. This makes the Mass Bulk Starter Stack accessible to anyone who wants to get serious about it, but is not yet ready for needles and injection protocols.

In addition, the half-life of both components is favorable. One dose per day is sufficient. No complex schedules. No multiple daily intakes. Just a routine that you can effortlessly maintain.

The Mass Bulk Starter Stack is designed for the serious beginner.

That may sound like a contradiction, but it’s exactly what most athletes need. Someone who already has a solid training foundation. Someone who has his nutrition in order. Someone who is ready to go to the next level, but doesn’t want to go straight into the depths with aggressive, multi-compound stacks.

If you’ve been training consistently for a few years and notice that the natural progression is stagnating, this is your logical next step.

This stack is also perfect for athletes who are coming back after a break. Or for experienced users who want to run a milder, entertaining cycle without the complexity of heavier protocols.

Results are always individual, but most users of this stack report some consistent effects.

The first is the increase in strength. Within two to three weeks, you notice that the weights that previously felt heavy suddenly become lighter. The barbell moves more smoothly. The repetitions become easier. You can train harder without breaking down earlier.

Second is the mass build-up. Not necessarily extremely dry, stage-ready mass, but full, round muscles that stay put. The combination of RAD-140’s anabolic effect and MK-677’s growth hormone-boosting effect results in a body composition that clearly changes.

Third is the recovery. Sleep becomes deeper. Muscle pain disappears faster. You feel fresher when you walk into the gym, even on days when you have trained heavily. That recovery is the hidden key to long-term progress.

Privacy is essential. That is why each Mass Bulk Starter Stack is packaged in a completely neutral, unrecognizable packaging. No logos. No brand names. No indication of the content on the outside.

Delivery within the Netherlands usually takes 1 to 2 working days. You order today. You start this week.

The demand for high-quality starter stacks is high. The stock is limited.
