EQUI-MASS™ — The EQ Precursor Formulated To Help Break The Hardgainer Plateau
Formulated for serious mass seekers pursuing meaningful gains.* For men who refuse to stay small.
You're eating 4,000+ calories a day.
Training 5-6 days a week. Sleeping 8 hours. Doing everything right.
And the scale barely moves. When it does? It's going to your waist, not your chest.
How long have you been stuck at the same weight? 6 months? A year? Longer?
That's not a discipline problem. It's a biological bottleneck—and EQUI-MASS is formulated to address it.*
You've heard it a thousand times. "Just eat more, bro." "You're not eating enough."
Except you ARE eating enough. You're eating until you're sick. And nothing happens.
Here's what's typically going on:
Barrier #1: The Metabolic Furnace
Some metabolisms burn through calories faster than others. What supports muscle growth on one guy may just maintain weight for you. Your body may need additional hormonal support to shift into building mode.*
Barrier #2: The Partitioning Problem
Even when you do gain weight, some bodies preferentially send nutrients to fat storage instead of muscle tissue. Poor nutrient partitioning means getting soft before getting big.*
Barrier #3: The Natural Ceiling
Your natural testosterone and protein synthesis can only support so much muscle growth. You may have hit the limit of what your current hormone profile can build.*
Here's the good news: EQUI-MASS is formulated to help raise that ceiling.* Your body still has the machinery to build muscle—it may just need the right signal.
EQUI-MASS uses three synergistic compounds designed to support muscle growth through different pathways. This isn't just "more testosterone"—it's a multi-pathway approach formulated specifically for men who struggle to gain.*
💥 COMPOUND #1: THE EQ PRECURSOR
1,4-OHP (1,4-Andro)
This compound is designed to convert to boldenone (EQ) in the body.* Known in the bodybuilding community for its association with protein synthesis, nitrogen retention, and red blood cell production.* This is why many users report being able to train harder, longer, and recover faster.*
Designed to support enhanced protein utilization from every meal.*
⚡ COMPOUND #2: THE STRENGTH DRIVER
17beta-{3-ketoethyl}-androsta-1,4-diene-3-one, 17a-ol — 200mg
Formulated to support aggressive strength gains and training intensity.* Many users report their lifts increasing on EQUI-MASS—more weight moved means more stimulus for potential growth.*
Users commonly report setting new PRs within the first few weeks.*
🛡️ COMPOUND #3: THE RECOVERY AMPLIFIER
3β-Hydroxy-5-androsten-17-one — 200mg
Designed to support natural testosterone production and recovery.* This helps maintain that full, pumped appearance many users report.* Also formulated to support libido and mood throughout your cycle.*
Train hard today, train harder tomorrow. Designed to help minimize burnout.*
*Individual results may vary. These statements describe the formulation intent and user experiences, not guaranteed outcomes.
We know some of you have considered actual gear. Maybe you've researched Equipoise (EQ). Maybe you know someone running it for their bulk.
Here's the reality: EQ is one of the most respected mass-building compounds in that world. Known for steady gains, increased appetite, enhanced recovery, improved protein synthesis.
EQUI-MASS contains 1,4-OHP—a legal precursor designed to convert to the same compound in your body.*
No needles. No prescriptions. No sketchy UGL sources. No legal risk. A legal alternative for men seeking real compound support.*
*1,4-OHP is a legal prohormone precursor. Conversion rates and results vary by individual. This product is not a controlled substance and is not equivalent to injectable compounds.
Individual experiences shared by select customers. Your results will vary based on diet, training, genetics, and compliance. These represent individual reports, not typical outcomes.
Week 1-2: Initial Response Phase
Some users report that recovery feels faster and pumps feel fuller. Some notice energy and training intensity beginning to improve. Early changes are individual and vary widely.*
Week 3-4: Strength Response Phase
This is typically when some users report more noticeable changes. Some report adding weight to their major lifts. Shirts may begin feeling tighter across chest and arms for some users.*
Week 5-8: Visibility Phase
Some users report that others begin noticing changes during this phase. The physique may take on what some describe as a fuller, denser appearance.*
Week 9-12: Consolidation Phase
Users who complete a full 12-week cycle with proper diet and training have reported meaningful progress toward their mass goals.* Strength improvements are commonly reported during this phase.*
⚠️ Real Talk About Mass Gaining:
Gaining significant weight always involves some combination of muscle, water, glycogen, and body fat. EQUI-MASS is formulated to optimize the muscle-to-fat ratio, but some body fat gain during a bulk is normal and expected.*
That's how real physiques are built. You bulk hard, then you cut. Anyone promising "100% lean gains" isn't being straight with you.
*Individual experiences vary significantly. Results depend on diet (caloric surplus), training, genetics, age, and compliance with protocols. No specific results are guaranteed.
💪 Meaningful mass gains — Quality weight, formulated to support muscle over fat*
📈 Progressive strength increases — Some users report adding weight to lifts*
🔄 Enhanced recovery — Train the same muscle group sooner with less soreness*
🍽️ Increased appetite — Eating may feel more productive*
👔 Clothes fitting tighter — Shirts stretching across chest and shoulders*
🦁 Enhanced training drive — Some report increased motivation to train*
*Based on select customer reviews and feedback. Individual results vary. These represent individual experiences, not guaranteed or typical outcomes.

*Comparison based on product category characteristics. Individual results vary. This is not a claim of equivalence to any category. Injectable steroids are illegal without prescription and carry significant health risks.
Dose: 2mL daily — split 1mL morning and 1mL pre-workout for stable levels
Cycle Length: 8-12 weeks. Most users report best results from completing a full cycle.
PCT: MANDATORY. Run full PCT protocol (Armidione + Cycle Support) for 4 weeks after cycle.
Diet: Calorie SURPLUS required. 500-750 calories above maintenance. Minimum 1g protein per lb bodyweight.
Training: Heavy compound movements. Progressive overload every session. Train 4-6 days per week.
💡 Pro Tip: Track everything. Bodyweight daily (morning, post-bathroom). Measurements weekly (arms, chest, legs). Lifts every session. When you see your progress, you'll want documentation of your transformation.
✓ EQUI-MASS May Be Right For You If:
✓ You're an experienced lifter who's been stuck at the same weight
You eat big, train hard, and nothing happens. Bulking has been frustratingly slow no matter what you try. EQUI-MASS is formulated for exactly this situation.*
✓ You're tired of looking like you don't lift
You train but nobody can tell. You want to look like you actually put in the work—imposing, thick, muscular. You want real visible development.*
✓ You want accelerated progress—not in 2 years, but soon
Formulated to support aggressive, accelerated progress when combined with proper diet and training.*
✓ You're willing to commit to the full protocol
This compound is designed to amplify your efforts—but you need to eat in a surplus and train hard. 4-5 meals a day minimum. If you can't commit, save your money.
✗ EQUI-MASS Is NOT For:
✗ Cutting or "staying lean"
This is a MASS compound. You will likely gain some fat along with muscle. That's how bulking works. Cut later.
✗ Beginners still making natural gains
If you've only been training 6 months, you're still making "newbie gains." Save your money. Come back when you've hit a real plateau.
✗ People who skip PCT
PCT is mandatory. Skip it and you may lose your gains and feel terrible for months. Don't be that guy.
Individual customer experiences. These are exceptional results and should not be expected. Your results will vary based on diet, training, genetics, and protocol compliance.
"I've been a hardgainer my whole life. 6'2", could never break through no matter what I ate. Ran EQUI-MASS and finally saw real progress. My arms finally filled out my sleeves. This is the only thing that's ever actually worked for me."
*Exceptional individual result reflecting this user's unique experience. This is not typical and your results will vary.
"Made serious progress on this cycle. All my lifts shot up significantly. People at the gym kept asking what I was doing differently. Bloodwork came back fine post-PCT."
*Exceptional individual result reflecting this user's unique experience. This is not typical and your results will vary.
"At 42, I thought my mass-building days were over. Ran EQUI-MASS out of desperation and saw real changes. My wife said I look better now than in my 20s. Shoulders exploded. Back got thick. Already planning my next cycle."
*Exceptional individual result reflecting this user's unique experience. This is not typical and your results will vary.
*Testimonials represent exceptional individual experiences. Results depend on many factors including diet, training, genetics, age, and compliance with protocols. These results are not typical and should not be expected by all users.
🔷 The Mass Monster Stack (Maximum Size)*
EQUI-MASS + URONABOL + MYO-11 + Cycle Support
EQUI-MASS for mass support. URONABOL for density and hardness. MYO-11 to support myostatin modulation.* This is the comprehensive option for serious hardgainers pursuing aggressive mass goals.*
🔶 The Quality Bulk Stack*
EQUI-MASS + URONABOL + Cycle Support
EQUI-MASS for mass. URONABOL to help keep gains dry and dense.* This stack is formulated to help optimize the quality of mass gained.*
🔷 The First-Timer Stack
EQUI-MASS Solo + Comprehensive PCT
Your first prohormone cycle should be simple so you can assess tolerance and response. Run EQUI-MASS by itself for 8 weeks. Follow with Armidione + Cycle Support for 4 weeks. This will help you learn how your body responds.
*Stack results vary by individual. These are formulation goals, not guaranteed outcomes.
What kind of progress might I see?
Results vary significantly by individual based on diet, training, genetics, and compliance.* Some users have reported meaningful mass gains when following the full protocol with proper caloric surplus and training. A typical bulk includes some combination of muscle, glycogen, water, and fat—that's normal.*
Do I really need PCT?
Yes. Non-negotiable. EQUI-MASS may suppress your natural testosterone production. Without PCT, you may crash hard—potentially losing gains and experiencing decreased libido and mood. Run Armidione + Cycle Support for 4 weeks minimum after your cycle.
Will the gains stay after I stop?
With proper PCT and maintenance calories, many users report retaining a significant portion of progress made.* You may lose some water weight post-cycle, which is normal. Continued training and adequate nutrition support retention.*
What about side effects?
Potential effects reported by some users: Increased appetite (often considered a plus for hardgainers), oily skin/acne (manageable with skincare), water retention (normal during bulk), increased training intensity. Most users report tolerating it well when running Cycle Support for organ protection.*
How does this compare to actual steroids?
Honest answer: They're different product categories. Injectable compounds are illegal without prescription and carry different risk profiles. EQUI-MASS is a legal prohormone precursor that offers a different approach. For many guys who've been stuck at the same weight, this legal option may provide the support they're looking for.*
*Based on customer-reported experiences. Individual results vary significantly. No specific outcomes are guaranteed.
The 60-Day Satisfaction Guarantee
Run EQUI-MASS for 8 weeks with proper diet and training.
If you're not satisfied with your experience — full refund within 60 days.
No hassle. Just satisfaction or your money back.
For Men Who Are Done Being Patient
You've been patient your whole life.
"Just eat more." "Give it time." "Keep being consistent."
And you're still not where you want to be.
Maybe it's time to stop waiting for permission. Maybe it's time to actually support your body's potential to build what you've been working toward.*
Your family sees a man who doesn't quit. Your kids see a father who takes care of himself. Your partner sees someone who refuses to accept decline.
EQUI-MASS is for men who are ready to take action.
⚠️ The Non-Negotiables For Results
1. EAT IN A SURPLUS: 500+ calories above maintenance. You can't expect growth in a deficit, even with supplementation.
2. TRAIN HEAVY: Progressive overload every session. The compound is designed to amplify training stimulus—give it something to amplify.
3. SLEEP 7-9 HOURS: Growth happens during recovery. Shortchange sleep and you shortchange potential results.
4. RUN CYCLE SUPPORT: Protect your liver and organs during the cycle. This isn't optional.
5. COMPLETE YOUR PCT: Or risk losing your gains. Your choice.

Every label screaming “science-backed.” Every ad promising “massive gains.”

If you don’t feel harder, stronger, and bigger in 30 days, you don’t pay. Period.
Now it’s on you to take the leap.
Start your cycle. Document it.
And in a few weeks, you might be the next guy DM’ing us:
“I can’t believe I didn’t start sooner.”
