RAD-MASS™ — The Testosterone Base That Breaks Every Plateau
High-dose 4-Andro. Direct test conversion. The foundation every serious cycle needs.
Same weights for 3 months.
Same physique in the mirror.
You're training like a savage but looking average.
Your natural testosterone can't support more growth. You've maxed it out.
RAD-MASS is the test base that smashes through that wall.
Why You Need More Testosterone To Grow
Let's be blunt about what's really happening.
After years of training, your body has hit biological walls that no amount of effort can break:
Wall #1: The Hormonal Ceiling
Your natural testosterone can only support so much muscle mass. You've built everything your current hormone levels allow. More food, more volume—none of it matters when testosterone is the bottleneck.
Wall #2: The Recovery Limit
Training breaks down muscle. Testosterone rebuilds it. Without enough test, you can't recover from the training volume needed to grow. You're either overtraining or undertrained—stuck in limbo.
Wall #3: The Stack Foundation Problem
Running prohormones without a test base? That's why you feel like garbage—low energy, no libido, joint pain. Every serious compound suppresses natural testosterone. Without a base, you're leaving 50% of gains on the table AND feeling like death.
RAD-MASS solves all three. It's the foundation everything else builds on.
Why 4-Andro Is The Perfect Test Base
4-DHEA is the most direct legal pathway to real testosterone. It converts with minimal steps and high efficiency. This is as close as you can get to actual testosterone without a prescription.
🔬 THE COMPOUND
4-DHEA (4-Andro) — 100mg per 2mL serving
4-Andro converts into testosterone via the enzyme 17β-HSD. This is a two-step conversion—far more efficient than regular DHEA or "test boosters." You're getting real testosterone elevation, not just "supporting natural production."
This is as close to TRT as you can get legally. Real testosterone, delivered as a legal precursor.
💧 THE LIQUID ADVANTAGE
Advanced Liquid Solution Delivery
4-Andro in powder capsules has garbage bioavailability—you absorb maybe 30-40%. Our liquid solution increases absorption to 70-80%+. More gets into your bloodstream, less gets wasted.
100mg of our liquid 4-Andro = 200mg+ of powder capsules. Maximum efficiency.
For Guys Who've Thought About TRT Or "The Real Stuff"
We know some of you have considered actual testosterone—either TRT from a clinic or gear from other sources.
Here's the reality: RAD-MASS gives you access to real testosterone elevation through a legal precursor pathway. 4-DHEA converts directly into bioidentical testosterone in your body. Same compound, legal delivery method.
No needles. No prescriptions. No clinic visits. No sketchy UGL sources. Just real testosterone results, legally.
What Actually Happens (Week By Week)
Week 1-2: The Foundation Phase
You feel more "on" immediately. Energy increases. Libido spikes. Training intensity goes up. Your body is getting the testosterone signal it's been missing. This is the base layer everything else builds on.
Week 3-4: The Strength Surge
Lifts that were stuck for months suddenly move up. You're adding 5-10 lbs weekly to major compounds. Recovery between sessions accelerates. You can train harder, more frequently. The plateau is officially broken.
Week 5-8: The Mass Building Phase
Scale is up 8-12 lbs. Muscles look fuller, thicker. Shirts fit tighter across chest and shoulders. People start noticing and commenting. This is what happens when you give your body the testosterone it needs to actually grow.
Week 9-12: The Complete Transformation
10-15 lbs of quality mass gained. Strength up 20-30% across all major lifts. Your physique looks different—more mature, more developed. Real, permanent muscle tissue that stays with proper PCT.
⚠️ Real Talk About Test Bases:
RAD-MASS contains 4-Andro, which WILL suppress your natural testosterone production. That's the point—you're replacing natural production with elevated exogenous levels.
PCT is mandatory. You're running a testosterone cycle, even if it's oral and legal. The results are worth it—but only if you do it right.
What You'll Actually See And Feel
💪 Explosive strength gains — Breaking through months-long plateaus within weeks
📈 Steady mass accrual — 10-15 lbs of quality muscle in 12 weeks
🔄 Enhanced recovery — Train harder, more frequently without overtraining
⚡ Elevated energy and drive — Feel "on" all day, not just in the gym
🔥 Increased libido and confidence — The alpha mentality testosterone brings
💧 Fuller, harder muscles — That "on-cycle" look even between workouts
Why Every Serious Cycle Needs A Test Base
| Scenario | With RAD-MASS | Without Test Base |
|---|---|---|
| Running 19-NANDRO | Massive gains, high libido, feel great | "Deca dick", no energy, joint pain |
| Running WIN-TEST | Dry gains + fullness, strength up | Flat muscles, weak, dry joints hurt |
| Running 1-ANDROL | Hardness + size, no low-T sides | Hard but flat, libido crashes |
| Training Intensity | Aggressive, focused, dominant | Tired, unmotivated, weak |
| Recovery Between Sessions | Fast, ready to go again quickly | Slow, constantly sore, dragging |
| Libido & Mood | High drive, confidence, alpha | Dead libido, depressed, irritable |
The verdict: RAD-MASS makes every other compound work 2-3x better while preventing the sides of low testosterone.
How To Run It
Dose: 1-2mL daily (100-200mg). Start with 1mL, increase to 2mL if needed.
Timing: Morning OR 30 minutes pre-workout. Empty stomach preferred for absorption.
Cycle Length: 8-12 weeks. Can run up to 16 weeks for advanced users with proper support.
PCT: MANDATORY. Run Muscle Support Stack (Armidione + Cycle Support) for 4 weeks minimum.
Diet: Works in surplus (mass) or deficit (recomp). Minimum 1g protein per lb bodyweight.
💡 Pro Tip: RAD-MASS is the perfect first cycle for someone stepping into prohormones. Single compound, well-tolerated, teaches you how to manage elevated testosterone. Run it solo for 10 weeks, follow with PCT, document everything. This is your education.
Who This Is Actually For
✓ You're running your first prohormone cycle
RAD-MASS solo is the smartest first cycle. One compound, predictable results, teaches you PCT management.
✓ You're stacking other prohormones and need a test base
Running 19-NANDRO, WIN-TEST, or 1-ANDROL? You NEED RAD-MASS as your foundation. Prevents low-T sides, amplifies gains.
✓ You've been stuck at the same strength/size for 3+ months
Your natural test can't support more growth. RAD-MASS raises that ceiling and breaks the plateau.
✓ You want to "gain plenty of strength" for compound lifts
Elevated testosterone = elevated strength. Bench, squat, deadlift—all will climb when test is no longer the bottleneck.
✗ This isn't for "quick shred"
Test builds mass and strength. Want to get shredded? Use WIN-TEST or HYDROXYGENIN. RAD-MASS is for building.
✗ This isn't for people who skip PCT
You're elevating testosterone exogenously. Natural production will shut down. PCT is mandatory to recover. No exceptions.
The 30-Day Plateau-Breaker Guarantee
Run RAD-MASS for 8 weeks with proper training and nutrition.
If you don't break through your plateau with measurable strength and size gains—full refund.
No hassle. No excuses. Just results or your money back.
Questions You're About To Ask
What exactly is 4-Andro?
4-DHEA is a true testosterone precursor—not a "booster." Through a single enzymatic conversion (via 17β-HSD), it transforms directly into bioidentical testosterone inside your body. You're not nudging natural production; you're supplying the raw substrate. This is real testosterone, delivered legally in precursor form.
Can I run RAD-MASS solo or do I need to stack?
Both work. Solo RAD-MASS is an excellent first cycle—10-15 lbs of quality mass in 10-12 weeks. OR use it as a test base when stacking other compounds like 19-NANDRO, WIN-TEST, or 1-ANDROL. Either way delivers results.
Do I really need PCT?
YES. You're running exogenous testosterone. Natural production will suppress significantly. Without PCT, you'll crash—low energy, no libido, depression, loss of gains. Run Muscle Support Stack for 4 weeks minimum after your cycle.
How much will I gain?
Solo RAD-MASS: 10-15 lbs in 10-12 weeks with proper diet and training. Stacked as test base with other compounds: 15-25+ lbs depending on what you stack. Quality gains that stay post-PCT if you do things right.
Why liquid instead of capsules?
Bioavailability. 4-Andro in powder capsules has poor absorption (30-40%). Our liquid solution increases absorption to 70-80%+. You get more actual testosterone conversion from less product. This is why liquid hits harder and faster.
What Serious Lifters Are Saying
"RAD-MASS was my first cycle. Ran it solo for 10 weeks. Gained 13 lbs, all lifts went up 15-20%. Felt amazing the whole time—high energy, great workouts, libido through the roof. Did proper PCT and kept 11 of the 13 lbs. This is the perfect introduction."
— Ryan K., 29, First Cycle
"I stack RAD-MASS with everything now as my test base. Running 19-NANDRO without it was miserable—no energy, no libido. With RAD-MASS? Gaining mass like crazy, feel like a beast, no sides. It's non-negotiable for any serious stack."
— Marcus D., 36, Experienced User
"Been stuck at 185 lbs for a year. Ran RAD-MASS for 12 weeks, hit 198 lbs. Bench went from 285 to 325. Finally broke through that wall. The liquid delivery is legit—you feel it kick in faster than any capsule I've ever taken."
— Jake T., 32, Plateau Breaker
