7 Things to Know About RAD-MASS Before You Buy
Read this in 3 minutes. Then decide.
1
It Gives Your Body the Raw Material to Make Real Testosterone
After 30, your testosterone drops 1–2% every year. By 40, you've lost a quarter of your peak. By 50, a third. No amount of training fixes a supply problem.*
RAD-MASS contains 4-DHEA (4-Androsterone) at 100mg per serving. Your body takes it and converts it into testosterone. Same molecule. Same pathway your body already uses.*
This is not a "test booster." It's a direct building block your body turns into the real thing.*
Think of it this way: Test boosters try to convince your body to make more. RAD-MASS gives your body the raw material so it actually can.*
2
Here's How You Know It's Actually Working
Most supplements don't require PCT (post-cycle therapy). That's not because they're gentle. It's because they don't do anything worth recovering from.
RAD-MASS requires PCT.
That means it's actually changing your hormones. It's raising your testosterone by giving your body a real precursor — and your natural production dips while it's doing that. When you stop, PCT brings everything back to normal.*
A useful rule: If a testosterone product doesn't need PCT, it probably isn't doing much. RAD-MASS needs PCT. That should tell you something.*

It's Nothing Like What You've Tried Before
If you've been disappointed by supplements, you're not wrong. Most of them are garbage. Here's why RAD-MASS is a different category entirely:
Most "Test Boosters"
✗ Herbal blends (tribulus, fenugreek)
✗ Proprietary labels hiding doses
✗ No hormonal effect at all
✗ No PCT needed (nothing happened)
✗ $40/month wasted
RAD-MASS
✓ Single compound: 4-DHEA, 100mg
✓ Full dose on the label. Nothing hidden.
✓ Direct testosterone conversion*
✓ PCT required (it's actually working)*
✓ HPLC-tested. Every batch.

Here's What It Feels Like (Week by Week)
Results depend on your training, diet, and consistency. But here's what customers typically report:*
Weeks 1–2: The switch flips. More energy. Better mood. Stronger gym drive. Most guys feel this within 7–10 days as the 4-DHEA enters your system.*
Weeks 3–5: Weights start moving. Lifts you've been stuck on for months go up. Recovery between sessions gets noticeably faster. The plateau is cracking.*
Weeks 6–8: Visible changes. Fuller, thicker muscles. Shirts fitting tighter. The mirror starts matching the effort. This is when people start asking questions.*
Weeks 9–12: Full transformation window. Meaningful size and strength gains. Because 4-DHEA builds real tissue — not water — what you gain stays after proper PCT.*

The Complete System (Not Just a Bottle)
RAD-MASS is a 3-phase protocol. Not a single product you take and hope for the best. Here's the full picture:
Phase 1 · On Cycle (8–12 weeks)
RAD-MASS: 2mL daily (100mg). Morning or pre-workout. Start at 2mL, bump to 3–4mL based on response. Run Cycle Support alongside for organ protection.

Phase 2 · PCT — Required (4 weeks min)
Arimidione + Cycle Support. This restores your natural testosterone after your cycle. Without it: lost gains, tanked energy, dead libido, mood swings. Non-negotiable. If you won't run PCT, don't buy RAD-MASS.

Phase 3 · Off Cycle (4+ weeks)
Let your body fully recover. Use non-suppressive products (Titan, Diobol, Uronabol, MYO-11) during this window to keep progressing without hormonal stress.*

Pick Your Goal. We'll Tell You What to Stack.
RAD-MASS is the foundation. What you add depends on what you're after.
First Cycle → RAD-MASS solo + PCT. One compound. Predictable results. The smartest way to start.
Maximum Size → RAD-MASS + 19-Nandro + Cycle Support. Test base + Deca precursor. For guys who want to fill out.*
Lean & Hard → RAD-MASS + Win-Test + Cycle Support. Dense, dry muscle. Zero water retention.*
Recomp → RAD-MASS + Win-Test + Hydroxygenin + Cycle Support. Build muscle and lose fat at the same time.*
Raw Strength → RAD-MASS + 1-Androl + Cycle Support. Dense, dry strength gains. The PR-smasher.*

Who It's For (and Who It's Not)
This is for you if:
✓ You're a first-timer ready for a real cycle (not another test booster)
✓ You're 35+ and can feel your testosterone declining
✓ You've been stuck at the same weights for months
✓ You need a testosterone base for stacking other compounds
✓ You've considered TRT but want a legal OTC option first
This is NOT for you if:
✗ You won't commit to PCT afterward — seriously, don't buy it
✗ You want a "quick shred" — look at Win-Test or Hydroxygenin instead
✗ You're under 21
✗ You have liver, kidney, cardiovascular, or prostate conditions
✗ You're looking for a magic pill without training and diet
Quick Answers
Tap to expand.
Thinking about TRT or gear?
4-DHEA converts into the same testosterone your body makes naturally. Same pathway. No prescriptions, no injections, no commitment to weekly shots for life.*
We're not claiming RAD-MASS equals TRT. TRT is medical-grade hormone replacement. RAD-MASS is a legal OTC precursor that many guys try first — and a significant portion decide they don't need that next step.
If your doctor has recommended TRT, follow their guidance. Results vary.*
Will this mess with my hormones?
Yes — that's the whole point. 4-DHEA raises testosterone by providing a direct precursor. Natural production dips while you're on cycle. This is normal and expected. That's exactly why PCT exists.*
Run Arimidione for 4 weeks after your cycle. It blocks estrogen and restarts natural production. Thousands of guys have run this protocol successfully.*
If you're concerned, get bloodwork before and after. No marketing copy replaces knowing your actual numbers.
Is this safe? What about my liver?
4-DHEA is non-methylated — it doesn't carry the liver toxicity of old-school banned prohormones. We still recommend Cycle Support during your protocol for overall organ protection.*
If you have pre-existing liver, kidney, cardiovascular, or prostate conditions, consult a doctor before using any hormonal supplement.
Can I run it solo or do I need to stack?
Both work. First cycle? Solo is the smartest play. One compound, predictable results, teaches you how your body responds before adding complexity.*
Experienced? RAD-MASS is the test base you run underneath other compounds (19-Nandro, Win-Test, 1-Androl) to maintain testosterone, energy, and libido while those compounds do their specific jobs.
Why liquid instead of capsules?
Bioavailability. Sublingual liquid bypasses much of the digestive breakdown that capsules go through — more active compound reaches your system per milligram.*
The tradeoff: it doesn't taste great. But you're not buying it for the flavor.
I'm on TRT. Can I take this too?
Talk to your prescribing doctor first. 4-DHEA converts to testosterone and will affect your hormone panel and potentially your TRT dosing. Many TRT users do add precursors, but medical supervision is the right move here.
I'm over 50. Is this safe for me?
A large portion of our customers are in the 40–65 range. Many came to us specifically because their testosterone has been declining and they wanted an alternative to TRT clinics.*
Recommended: (1) Get bloodwork first for a baseline. (2) Consult your doctor, especially if on medications. (3) Run Cycle Support for the full duration. (4) Start at 2mL and assess before increasing.
Don't skip the precautions because you're eager. The guys who get the best results are the ones who do this responsibly.
Every serious cycle starts with a testosterone base.
100mg 4-DHEA per serving · Direct conversion · Liquid delivery · Lab tested · PCT protocol included
Important: RAD-MASS contains 4-DHEA (4-Androsterone), a testosterone precursor. It will support testosterone levels and may temporarily suppress natural production. Post-Cycle Therapy (PCT) is strongly recommended. Consult a healthcare provider before use, especially if you have any medical conditions or take medications. For adult males 21+ with training experience. Not suitable for women, individuals under 21, or those with liver, kidney, cardiovascular, or prostate conditions. *Individual results vary.

Why trust us when every other supplement brand has lied to you?
You’ve tried it all.
Powders. Pills. Pre-workouts. Test boosters. Protein tubs stacked to the ceiling.
Every label screaming “science-backed.” Every ad promising “massive gains.”

Plateaus. False hope. Wasted money. Weak results.
