Does EQUI-MASS actually work?
If you have paid for big labels and fairy-dust doses before, your doubt is earned. So skip our promises and read a buyer.

What is in EQUI-MASS, and how much?
A label can say anything, so we test the bottle. Each 2 mL serving holds two actives, at 200 mg each. 1,4-OHP is the main active, formulated to support protein synthesis and nitrogen retention for full, dense size.† The second active works beside it, formulated to support strength and a thick, solid look.† Our HPLC test of batch 251028-001 on Oct 28, 2025 found 212 mg and 208 mg. Both tested above the label. The lab report is lower on this page.

Great product...I've seen massive gain...on my small 54yr old frame
Verified buyer review and photo. Some reviewers got a discount for adding a photo. Results vary.†
How do I take it?
No needle and no prescription. Take 2 mL a day, with 1 mL in the morning and 1 mL before training. It tastes bad, so keep water or juice ready as a chaser. EQUI-MASS is built for a bulk, and size needs food. Eat 500 to 750 calories over maintenance, with about 1 gram of protein per pound of body weight. Run it for 8 weeks, which is 2 bottles, with Cycle Support from day one. Then stop, and take Arimidione and Cycle Support for 4 weeks of PCT. Then take 4 weeks off. Every kit on this page includes the PCT.

Same here. Making hard muscle after only a week. Hate the taste but will keep using it because it really works.

Is EQUI-MASS safe?
Men have taken EQUI-MASS for more than five years. Vintage Muscle is a US company with six years in business, and it sells EQUI-MASS legally and in the open. The formula is HPLC lab tested, and it has 671 reviews on this page. EQUI-MASS is a hormonal product, and that is why it comes with a plan. It lowers your natural testosterone while you take it, so every cycle ends with 4 weeks of PCT. Every kit on this page includes the PCT. As one customer in his 40s put it: “honestly if I need pct then the stuff has got to be good.”
EQUI-MASS is for men 21 and older who train. Some men notice side effects, and the full list is in Quick answers lower on this page. If you feel unwell, stop and talk to your doctor. Talk to a doctor first if you have a medical condition or take any medicine, including TRT.

What will I notice, and when?
In weeks 2 to 3, buyers write about fuller pumps and stronger lifts.† Strength shows before size. Judge the mirror and your shirts after bottle 2, in weeks 6 to 8.† Results vary with your food, training, and sleep.† Size needs extra food, so eat like you mean it. The first person to notice may not be you. 77% of returning customers surveyed said someone noticed a change in them. A wife or partner was the most common answer.

Verified EQUI-MASS Results
You should be furious at the supplement industry.
You've dumped hundreds of dollars on chalky mass gainers, underdosed retail test boosters, and GNC placebos—only to look identical 60 days later. You have every right to be cynical. Here is what real guys who train like hell wrote after their first cycle:
Victor C. · Verified Buyer
Was very surprised, and stoked, at how well it has worked. Hoping to continue to gain more mass, but satisfied with my progress so far. Getting ready to place another order!
Robert C. · Verified Buyer
I was on a weight loss journey and lost a substantial amount of muscle. I wanted a product to help rebuild it. After extensive research I landed on Vintage muscle products. I have used quite a few of them and all of them do exactly what they say they will. As long as you're willing to put in the work.

The Biological Trap
Why training harder and eating more stops working.
Creatine and whey protein got you past the beginner phase. But once you hit your mid-30s and 40s, your body shifts into preservation mode. You hit three biological brick walls:
01
Anabolic Resistance
Your muscle tissue stops responding to normal protein intake. You force-feed 3,500 calories a day like a second job, but protein synthesis idles.†
02
Nutrient Misdirection
Without a dominant anabolic signal, surplus carbohydrates and amino acids bypass depleted muscle cells and spill straight into visceral gut fat.†
03
Recovery Bankruptcy
Heavy squats and deadlifts leave you crippled for 5 days. You can't train with the frequency required to force real hyper-trophy.†
EQUI-MASS forces an aggressive anabolic partition: food builds muscle, not gut fat.†
The Formula
Two heavy-hitting actives. 400 mg every single day.
No proprietary blends. No fairy dusting. 2 mL delivers 200 mg of 1,4-OHP and 200 mg of raw androgenic support. When our chemist ran batch 251028-001, it clocked in at 420 mg total active payload.†
1,4-OHP molecular architecture: engineered for massive nitrogen retention without bloating.
Liquid Bioavailability: Traditional prohormone capsules get destroyed by first-pass liver breakdown. EQUI-MASS delivers liquid suspension actives directly into circulation.
200 mg per serving
1,4-OHP
17β-(1-ketoethyl)-androsta-1,4-dien-3-one, 17α-ol

The 8-Week Transformation Clock
What happens when you flood your body with 400 mg daily.
One bottle covers 4 weeks. A serious transformation requires 2 bottles (8 full weeks). You feel the compound ignite in your blood before you see the shirts stretch.†

The Stark Reality
Bulking alone makes you fat. EQUI-MASS forces it into muscle.†
Shoveling food without an active partitioning agent is a recipe for a dad bod. Here is what happens to your body with and without EQUI-MASS:
Standard Bulking Alone
- Surplus calories convert into stubborn waistline fat
- Bloated face and watery, soft muscle tissue
- Lifts hit a frustrating wall after 3 weeks
- Months of miserable dieting required to strip the fat off
Bulking + EQUI-MASS
- Calories routed directly into dry muscle synthesis†
- Rock-hard, dense tissue that fills your shirts†
- Sustained weekly strength PRs on bench, squat, deadlift†
- Rapid recovery so you can train heavy 5 days a week†
Looking for maximum hardness and density? Stack EQUI-MASS with Uronabol for extreme muscle definition. See stacks below.
Strict Qualification
Who this is for (and who should leave this page).
Pull the trigger immediately if:
- You bust your ass in the gym, but the mirror hasn't changed in 12 months.
- Your shirts hang loose on your shoulders while your gut pushes against your belt.
- You used to be big and strong in your 20s, and you refuse to settle for looking like a soft, fragile older man.
- You want to walk into any room and command respect as the strongest father or guy there.
- You're sick of spinning your wheels with GNC test boosters and want real hormonal leverage without needles.
- You are committed to eating in a surplus and completing the full 4-week PCT.
Doug K. · 61 Years Old
At 61 years old, I am amazed at my progress on these products! I am in the best shape of my life. I have built muscle mass with low body fat percentage for my age. My workout energy is great and my pumps are as well.
Do NOT buy this if:
- You want to be shredded and dehydrated right now. EQUI-MASS builds raw, thick size. For cutting, take WIN-TEST.
- You refuse to eat in a 500+ calorie surplus. Muscle cannot be manufactured out of thin air.
- You think you can skip post-cycle therapy. EQUI-MASS temporarily suppresses natural output; you MUST run 4 weeks of PCT to solidify your gains.
- You are under 21, looking for a magic shortcut, or compete in drug-tested athletic federations.
Straight Talk on Side Effects: Real compounds carry real metabolic responses. You will experience massive appetite increases and some intra-muscular water fullness. Start Cycle Support on Day 1 to safeguard liver values, and run the required PCT to lock in your mass.

Straight Answers
Frequently asked questions.
What is PCT and why is it mandatory?
EQUI-MASS delivers real anabolic compounds that temporarily suppress natural production during the cycle. Post-Cycle Therapy (PCT) is the 4-week window immediately following your cycle where you run Arimidione and Cycle Support.
PCT prevents estrogen rebound (chest fat), reactivates natural hormone balance, and locks in the muscle tissue you just built so you don't lose an ounce. Every kit on this page includes the complete PCT arsenal.
How does it taste?
It tastes terrible. Anyone telling you active prohormone liquids taste like candy is selling you flavored sugar water from GNC. EQUI-MASS tastes like high-octane racing fuel because it is packed with real chemical actives. Take your 1 mL dropper, shoot it to the back of your throat, and chase it with 4 oz of orange juice or water.
How many bottles do I need for a real cycle?
Each bottle contains 60 mL (30 servings of 2 mL), covering exactly 4 weeks. Real muscular hyper-trophy requires an 8-week run, which means you need 2 bottles of EQUI-MASS plus PCT. That is why our B2G2 kits are bundled for 12 complete weeks.
I’m in my 40s, 50s, or 60s. Am I too old for this?
You are our primary customer. The median age of Vintage Muscle lifters is 46, with over 40% in their 50s and 60s. Your muscle cells don't forget how to grow; they are simply starving for the hormonal signal they had 20 years ago. As long as your cardiovascular and liver baseline is healthy, EQUI-MASS is built to restart that signal.†
Will EQUI-MASS cause hair loss or chest fat?
If you are genetically predisposed to male pattern baldness, high androgenic environments can accelerate shedding. Estrogen conversion is kept in check by running Arimidione during PCT to prevent chest fat accumulation. Always run Cycle Support from Day 1.
I have been burned by test boosters. Why is this different?
Over-the-counter retail test boosters use trace herbs like Tribulus that do nothing for muscle growth. EQUI-MASS delivers 400 mg of 1,4-OHP and androst-4-en compounds—molecules structurally engineered to trigger nitrogen retention and tissue synthesis. We publish our 3rd-party HPLC laboratory testing on this page proving exact mg dosages. If it fails to perform, our 30-day empty bottle guarantee has you covered.
Can I keep taking creatine and pre-workout?
Yes. Keep your creatine, whey isolate, and pre-workout. EQUI-MASS acts as the anabolic amplifier that forces those nutrients into deep muscle storage.
Your frame is waiting. Now go fill it out.

- Exclusively for healthy adult men 21 and older with consistent resistance training experience. Prohibited for women or individuals with liver, renal, or cardiovascular impairments.
- Consult your licensed physician prior to initiating any hormonal supplement protocol.

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.

Every formula is pure, potent, and HPLC-tested. No cheap junk. No under-dosing. Just real compounds that fuel size, strength, and recovery.

That’s why we back everything with a 100% money-back guarantee.

I'm 50 years old Thanks Vintage Muscle for this road to recovery. .

Love this stuff!!! Been using this for 4 weeks now and I’ve seen a big improvement in my pull-ups and pushups. I don’t weightlift, I only do calisthenics. My daughter who is 60 pounds gets on my back for pushups. I went from doing sets of 30 to sets of 50 in the first week! And 5 reps more on “wide” pull-ups per set. This stuff is the real deal
Working great so far
I dropped 70 lb and need something to help me put on muscle.
After my first week i feel great. My arms have been rock solid and full constantly. My sleep has been more restful. I'm 50 years old and I've been recovering like I'm 25 again. I'm loving the early results. Thanks Charles Taylor Jr
Just got back in the gym after a few years off 4 yrs ago maxing 315 on bench 5 weeks ago maybe 185. Im at 235 and the whole process just seemed easier. Less sore, less fatigue, less pain from previous injuries. Definitely love this stuff, Definitely works. Try it for 6months if you dont like it get your money back guarantee, na just kidding only said that so you know im not a bot.
So far its hard to tell if im really gaining any weight or mass. I am definitely losing fat and replacing it with muscle no doubt but that could be due to alot of things was working out long before using this stuff well about a month before and I want to say that yes I am noticing a difference and its good. Is it as much as they claim you will? Idk that i would say that but I will say I do like it and its not hurting my gains at all so really long story short time will tell give me another month as only been using this stuff not quite 2 weeks so in all fairness I feel its hard to leave a real honest review yet!!
I'm at week 4 of using this product and the gains are huge!
I was on a weight loss journey and lost a substantial amount of muscle. I wanted a product to help rebuild it. After extensive research I landed on Vintage muscle products. I have used quite a few of them and all of then do exactly what they say they will. As long as you're willing to put in the work.
Noticeable gains and strength. Only product that i have seen gains with!
Love it , 2 months on one off
I have been putting on some serious clean size with this product. I strongly recommend anyone competing or just your everyday person who loves to train. I’m definitely ordering this again. Love it.
Was very surprised, and stoked, at how well it has worked. Hoping to continue to gain more mass, but satisfied with my progress so far. Getting ready to place another order!
Mad gains. One my third bottle of EquiMass. Going to cycle off and start WinTest for my summer shred.
I work Gates Rubber, and sometimes my job can be physically demanding. I would come home hurting from my neck to my toes. Since I started taking equi mass I sleep more soundly and my muscles recover from my workouts in a day. No more aches and pain. I'm 50 years old and still got it!
This stuff works great. More weight, more reps, more muscle and faster recovery.
Love it! Burns like fire tho but I believe it works!
Product is for real I am half way through my second consecutive 4 week cycle, will be purchasing more after my 4 week break
My weight has stayed the same but I'm starting to get alot more definition. Also I have way more energy and and I've increased weight in every lift. Im really impressed so far.
So far has been good. I actually like the flavor. Its strong and has a mint taste. I was already on a supplement and I decided to add this since its a stacking tincture. I have noticed the fat on my arms disappearing I even saw a vein in my bicep on my last workout. Seems to do exactly what it says and as far as muscle supplements go....thats Amazing. Good job Vintage Muscle. I've already spread the word.
2 on 1 off with the way I eat is doing wonders
I love it!!! I gained 22 lbs in the last 2 months and have never past 151. I Feel Great and more confident about myself!!
It works
So far so good. Felling strong and focused. Can't wait for later results. The pumps are insane.
