You Eat Big. You Train Hard. The Food Lands on Your Gut.
Full, thick muscle that fills your shirts. The work you put in finally shows up as size.†
You hit your calories and never skip a session. The scale stalls, or the gain lands on your waist. EQUI-MASS is built to turn that work into real size, with 400 mg of actives in every serving.†

You should be skeptical.
You have finished bottles of mass gainers and boosters and looked the same on the last day. Read what three verified EQUI-MASS buyers wrote.
Victor C.
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.
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.
Matt M.
This stuff works! I'm 60 yrs young. And I notice a huge difference when I use Equi-mass. I recommend it to anyone trying to pack on muscle.

“I put my name on NOTHING I don't believe in. Period.”
The problem
Three walls stand between your plate and the size you want.
Creatine, protein, and hard training got you this far. Your effort is fine. After a few years, more food and more sets stop adding size.
01
The stall
You add calories week after week, and the scale sits still. Eating more starts to feel like a second job.†
02
Soft gains
When the scale does move, the weight lands on your waist. Your chest and arms look the same.†
03
Slow recovery
Heavy days leave you sore for most of the week. You cannot train hard often enough to grow.†
EQUI-MASS is built to take on all three walls at once.†
What is inside
Two actives. 400 mg a serving.
Each 2 mL serving holds 200 mg of each active. Our lab found 420 mg in total. Here is each one and its job in the formula.†
The 1,4-OHP molecule, drawn from its real chemical structure.
Reading the name: The “1,4” marks two double bonds in the first ring. The “17α” marks the hydroxyl group on carbon 17. Both are labeled in the diagram.
200 mg per serving
1,4-OHP
17β-(1-ketoethyl)-androsta-1,4-dien-3-one, 17α-ol
It is the main active, formulated to support protein synthesis and nitrogen retention for full, dense size.†
Label: 200 mg · Lab test: 212 mg
200 mg per serving
Second active
3β-hydroxyandrost-4-en-17-one
It works beside 1,4-OHP, formulated to support strength and a thick, solid look.†
Label: 200 mg · Lab test: 208 mg
HPLC tested · Oct 28, 2025
Batch 251028-001. Both actives tested above the label, at 212 mg and 208 mg. Our chemist ran the test in-house with method SOP VM-106. See the lab report
The timeline
What 8 weeks of EQUI-MASS feels like.
One bottle lasts 4 weeks, so a full cycle takes 2 bottles. You feel it first and see it later. Results vary with your food, training, and sleep.†
Day 1
Start
Take your mirror photos. Start Cycle Support the same day.
Weeks 2–3
Feel it
Buyers write about fuller pumps and stronger lifts first.†
Weeks 6–8
See it
Judge the mirror and your shirts after bottle 2. Strength shows before size.†

Weeks1–4
Bottle 1: the push
Bottle 1 is built to fill out your pumps and push your lifts while you eat big.†
Warren S.
I’ve always been a string bean my whole life. It’s never mattered what my routine or supplement intake was until I found Vintage Muscle and they’re Equi-Mass. After 3 weeks I’m finally starting to see results I’ve been chasing for years now! Thank you Vintage Muscle!
-
Weeks5–8
Bottle 2: the size shows
Same dose, same surplus. Bottle 2 is built to fill out your shirts across the chest, arms, and shoulders.†
Edward W.
Been using the equimass for 5 wks and it worked amazingly just as it was described huge mass gain love all your products
The difference
A surplus adds calories. EQUI-MASS is built to turn them into size.†
Food and training build the base, and that job matters. How much of the surplus shows up as muscle is a separate job. That is why so many hardgainers eat more and still look the same.
Bulking alone
- Adds calories and scale weight
- Extra weight can land on your waist
- Lifts can stall for months
Bulking + EQUI-MASS
- Built for full, thick size†
- Built to support strength gains†
- Built to support recovery between sessions†
Want a denser, harder look on top of the size? Pair EQUI-MASS with Uronabol. See the stacks below.
The fit
Who it is for (and who it is not).
This is for you if:
- You eat big and train hard, and the scale has not moved in months.
- Your shirts used to fit tight across the chest, and now they hang.
- Creatine and protein got you this far, and your progress has stalled.
- You are coming back after a long break and want your size back.
- You want to be the strongest dad in the room.
- You will eat in a surplus and run the full PCT.
Doug K.
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.
This is not for you if:
- You want to get lean and dry. EQUI-MASS adds size and some water. Look at WIN-TEST.
- You will not eat in a surplus. Size needs extra food.
- You do not plan to run post-cycle therapy (PCT). EQUI-MASS suppresses natural testosterone, so 4 weeks of PCT after each cycle are required.
- You compete in a drug-tested sport or serve in the military.
- You are under 21, or you have a liver, kidney, or heart condition.
About side effects: EQUI-MASS can raise your appetite and add some water weight. Some men get skin breakouts. Run Cycle Support from day one, and get blood work before and after your cycle.

Increased strength, longer workouts, feeling younger than 45. Great product.

It was so hard to put on weight and turn it into muscle. This was the missing link. It’s not magic liquid that taste good and you don’t have to do anything to build muscle but an amplifier for the work you put in. Will be a long term customer

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.

PCT, in plain words
- Why you need it: EQUI-MASS suppresses your natural testosterone while you take it. PCT is the 4 weeks right after your cycle.
- Arimidione: It is formulated to support healthy estrogen balance and natural testosterone production after a cycle.†
- Cycle Support: Its label lists three blends: EstroControl, TestSupport, and LivSupport. It is built to support liver health and hormone balance from day one to the end of PCT.†
- In the kits: EQUI-MASS and 19-NANDRO need PCT. Uronabol and MYO-11 do not need PCT on their own.
Every kit below includes the full PCT.
Tip: Every bulk adds some water and a little fat with the muscle. To harden up later, run a WIN-TEST cycle after your off weeks.†

Questions
Quick answers.
What is PCT, and do I need it?
PCT stands for post-cycle therapy. It is the 4 weeks right after your cycle, when you stop EQUI-MASS and take Arimidione and Cycle Support.
EQUI-MASS suppresses your natural testosterone while you take it, so every EQUI-MASS cycle needs PCT. Every kit on this page includes it.
How many bottles do I need?
Each bottle has 30 servings of 2 mL, enough for 4 weeks with a couple of days to spare. A full 8-week cycle takes 2 bottles.
How does AutoShip work?
AutoShip sends a bottle every 4 weeks at $65.99, so two shipments cover one 8-week cycle. An every-8-weeks plan is also $65.99 a bottle.
AutoShip renews until you change or cancel it. You can do either any time in Manage Subscriptions.
How do I take it, and how does it taste?
Take 2 mL a day. Take 1 mL in the morning and 1 mL before training.
It tastes bad. Keep water or juice ready as a chaser.
Do I need to eat more?
Yes. EQUI-MASS is built for a bulk, and size needs extra food. Aim for 500 to 750 calories over maintenance.
Get about 1 gram of protein per pound of body weight every day.
Will EQUI-MASS cause hair loss?
It can speed up hair loss in men who are prone to it. If your father and grandfather kept their hair, your risk is lower.
If your hair is a top worry, take the 60-second quiz first. It can point you to a better fit.
What side effects should I know about?
EQUI-MASS suppresses your natural testosterone while you take it, which is why PCT is required.
Other possible effects are a bigger appetite, some water weight, and skin breakouts. Run Cycle Support from day one.
I am on TRT. Can I use EQUI-MASS?
Talk to the doctor who prescribes your TRT before you start. EQUI-MASS affects your hormone levels, and your doctor needs to know that to read your blood work.
Will EQUI-MASS show up on a drug test?
It can. If you compete in a drug-tested sport or serve in the military, check your testing rules before you start. We cannot promise you will pass.
I am over 50. Will it work for me?
You are in good company. The median age our customers tell us is 46. Age alone is not a reason to sit this out. Buyers on this page include men aged 45, 60, and 61. Results vary.†
Self-reported by 297 customers who shared their age in our post-purchase surveys, Jun 27 – Oct 24, 2026.
If you have a medical condition or take any medicine, talk to your doctor first.
I have been burned by other supplements. Why trust this one?
Fair question. A mass gainer adds calories, and EQUI-MASS is built to help those calories become size.†
The label says 200 mg of each active per serving. Our HPLC test of batch 251028-001 found 212 mg and 208 mg. See the lab report. Your first bottle also has a 30-day money-back guarantee, even if you open it.
Can I keep taking creatine and protein?
Yes. Keep your creatine, protein, and pre-workout. If you take any medicine or have a medical condition, talk to your doctor before you start.
The frame is still there. Now fill it out.

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.”
And what happened?
Plateaus. False hope. Wasted money. Weak results.
That’s because most of the industry is built on fillers, caffeine, and fairy dust doses. Lies packaged in shiny tubs.
Vintage Muscle is different.
We don’t push hype—we push hardcore precursors designed to actually change your results.
Every formula is pure, potent, and HPLC-tested. No cheap junk. No under-dosing. Just real compounds that fuel size, strength, and recovery.
Don’t take our word for it. Look at the reviews. Thousands of lifters already transformed.
And if you’re still skeptical—we get it. You’ve been lied to too many times.
That’s why we back everything with a 100% money-back guarantee.
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.”

I love it and I can’t wait to try other products from you guys!
Pushing 50 been using products for years with great results. People will accuse you of using illegal anabolics...
I love this product and it works so well and putting in the work with great results makes me appreciate it even more!
So far so good. Noticing small differences
been waking up better less soar and i feel tight around my muscles!
Great product, I feel it the momement it hits my tongue. The pump it gives lasts my entire workout. Great edge for a 66 year old.
I’m loving this stuff. My pumps are amazing and people are always asking what I’m using
Hi my name is Jesse,im 63 years old pretty much my last rodeo for building size and getting toned I feel. this product tastes horrible but works very well I've probably put on an inch in arms, chest and on top of good diet protocol and pretty much carnivore at this point I've lost 42 LB. these are good products I'll be checking out some others in the near future, thank you
Got bigger than I was before. I am definitely going to keep taking this to keep progressing
Equimass kicked in on day 8 love it feel incredible I recommend to everyone!!
I've always been a big strong man. I hit my peak strength in my 30's. I benched 465 lbs. ,Dead lifted 585 lbs., and my squats were up to 585 lbs. for three reps. When I was almost 38 years old I started noticing my body wasn't recovering like it used to. I had hit a wall in my gains. Now I'm tearing down the wall and building myself back to better than I was. I'm 50 years old Thanks Vintage Muscle for this road to recovery. .
The gains are real the vintage muscle product line is legit stuff depending on your fitness goals you’ll definitely see improvements gotta be consistent though no half assing. it works if you work hit the gym hit your calorie goals hit your protein goals you won’t be disappointed!
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.
Good stuff
more reps and definitely gaining more muscle
Just saying these supplements work! I have been training for 25 plus years, taking many supplements! Most stuff I felt worked are no longer on market! But Vintage Muscle has changed that! 💯 stuff works
It was so hard to put on weight and turn it into muscle. This was the missing link. It’s not magic liquid that taste good and you don’t have to do anything to build muscle but an amplifier for the work you put in. Will be a long term customer
