Loren G.
I started using Vintage Muscle a few months ago after trying countless supplements over the years. Honestly, nothing has worked for me like Vintage Muscle. I’ve noticed a real difference in how I look, but even more impressive is the strength I’ve gained. After being stuck on a plateau for years, I’m finally lifting heavier and seeing consistent progress again. I’m excited to see where I’ll be in the months ahead!
David L.
I’m 54, recently started lifting again after years of not training. I am absolutely impressed with this stack!

“I F@#$%&! LOVE THIS STUFF”
The problem
Three walls block the size you should see.
You did the work. Food and training built your base. Three things keep the next layer of muscle out of reach.
01
The plateau
You run the same program on the same food. Your numbers have barely moved in months.
02
Flat muscle
The pump fades an hour after you rack the bar. At rest, your chest and arms look flat.
03
Slow recovery
One hard leg day costs you three days. Fewer good sessions add up to slower progress.
RAD-MASS is built to take on all three walls at once.*
What is inside
One active. 100 mg a serving.
Each 2 mL serving holds one active, and the label lists its dose. Here is the active and its job in the formula.*
The 4-androstene-3β-ol,17-one molecule, drawn from its real chemical structure.
100 mg per serving
4-Androstene-3β-ol,17-one
3β-hydroxyandrost-4-en-17-one · C₁₉H₂₈O₂
It is the only active in the formula. It is formulated to target lean size and fullness in your chest, shoulders, and arms.*
Label: 100 mg per 2 mL serving
Read the name
4-ene
A double bond at carbon 4
3β-ol
An OH group on carbon 3, pointing up
17-one
A ketone group on carbon 17
The full name points to one exact molecule. Our HPLC test looks for that exact molecule.
HPLC tested · May 16, 2025
We tested batch BC051425, from our earlier 1 oz bottle. It measured 101 mg per 1 mL serving against a 100 mg label claim. Today's 2 oz bottle holds 100 mg per 2 mL. Our chemist ran the test in-house with method SOP VM-103. See the lab report
The timeline
What 8 weeks of RAD-MASS feels like.
One bottle lasts 4 weeks, so a full cycle takes 2 bottles. Here is what each bottle is built to do. Results vary with your training and food.*
-
Weeks1–4
Bottle 1: strength and pumps
Bottle 1 is built to drive strength and harder pumps. Log every lift, so you can see the bar move week by week.*
Raul C.
I am going on week 3 and I have noticed that I can lift a little bit more weight and my wife is starting to see a difference on my looks
-
Weeks5–8
Bottle 2: size you can see
Bottle 2 is built for fullness that stays after the pump fades. Your chest and arms look fuller at rest, and your shirts fit tighter.*
Robert M.
I was skeptical at first, especially with the taste. At the end of my first cycle I noticed gains in my chest and more definition in my biceps. Coming into my second cycle and I'm noticing more strength and feeling fuller. Almost like a constant pump. I've recommended these supplements to others.
The difference
Creatine got you here. RAD-MASS is built for the next step.
Keep your creatine, protein, and pre-workout. They fuel your training. RAD-MASS is a prohormone, a separate category built for size past a plateau.*
Basic stack alone
- Fuels your training
- Gains slow after the first year
- Can leave you stuck at one size
Basic stack + RAD-MASS
- Built for lean size you can see*
- Built to push strength on the bar*
- Built for fuller muscle at rest*
For more size support, pair RAD-MASS with 19-NANDRO. See the stacks below.
The fit
Who it is for (and who it is not).
This is for you if:
- You train at least three days a week, and your size has stalled.
- Your basic stack stopped adding size.
- You want a fuller chest and arms that fill out your sleeves.*
- You are back in the gym after years away, and you want to rebuild.
- You want to be the strongest dad on the sideline.
- You will run the full plan, including 4 weeks of PCT after the cycle.
Elliott C.
Not bad for 72 IMHO.
This is not for you if:
- You want to cut fast. RAD-MASS is built for size. Look at WIN-TEST or Hydroxygenin instead.
- You expect results without training and food. The work stays yours.
- You do not plan to run post-cycle therapy (PCT). RAD-MASS suppresses natural testosterone, so 4 weeks of PCT after each cycle are required.
- You are drug tested for sports, the military, or work.
- You are under 21, or you have a liver, kidney, heart, or prostate condition.

Bashkim P.
I've been using vintage muscle products for several months I personally love it and always recommend it ... P.S. P.C.T. IS IMPORTANT 💪🏽🦈🌊
Tip: RAD-MASS can run up to 12 weeks. For a 12-week cycle, add one more bottle and one more Cycle Support, then start PCT in week 13.
PCT is in every kit: All four stacks below need PCT. Each kit includes Arimidione and Cycle Support for all 4 weeks.

Harmon H.
Started with a cycle of 1-Androl and noticed lifts getting easier. After some time off, I started a new cycle of 1-Androl and Rad-Mass. I’ve recently hit a PR on overhead press, hit a snatch weight that I haven’t touched in years, and squats are moving easy. I was skeptical of the claims at first, but I’m a believer now.

Questions
Quick answers.
What is PCT, and when do I start it?
PCT stands for post-cycle therapy. It is the 4 weeks right after your cycle. Start it the day after your last RAD-MASS dose.
Take Arimidione and Cycle Support for those 4 weeks. RAD-MASS suppresses your natural testosterone, so every cycle needs PCT, even a short one.
What is a prohormone?
Prohormone is the name of the supplement category RAD-MASS belongs to. Prohormones like RAD-MASS run in cycles.
They suppress your natural testosterone while you take them. That is why every cycle ends with 4 weeks of PCT.
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. A 12-week cycle takes 3.
Can I run cycles back to back?
Run one cycle at a time. Finish 4 weeks of PCT and 4 weeks off before you start the next one.
How does AutoShip work?
AutoShip sends a bottle every 4 weeks at $65.99, so two shipments cover one 8-week cycle. You can change or cancel it any time in Manage Subscriptions.
How do I take it, and how does it taste?
Take 2 mL a day. Take it all at once, or split it between the morning and 30 minutes before training.
It tastes strong, with a peppermint bite. Robert mentions the taste above. Keep a chaser ready, like orange juice.
Will RAD-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?
RAD-MASS suppresses your natural testosterone while you take it, which is why PCT is required.
Other possible effects are acne on the back and shoulders, a bigger appetite, and a shorter temper. Hair can shed faster if you are prone to it.
I am on TRT. Can I use RAD-MASS?
Talk to the doctor who prescribes your TRT before you start. RAD-MASS affects your hormone levels, and your doctor needs to know that to read your blood work.
Will RAD-MASS show up on a drug test?
It can. If you are tested for sports, the military, or work, check your testing rules before you start. We cannot promise you will pass.
I am over 50. Will it work for me?
Age alone is not a reason to sit this out. Buyers on this page range from 45 to 72. Results vary.*
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. RAD-MASS has one active, and the label states its dose of 100 mg per 2 mL serving.
In May 2025, we tested batch BC051425 from the earlier 1 oz bottle. It measured 101 mg per 1 mL serving. See the lab report. Your first bottle also has a 30-day money-back guarantee.
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 man you used to be is still in there. Build him back, one bottle at a time.

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.”

Overall rating: 4.8 / 5 from 1651 reviews.
Taking Anadrol, Rad and Nandro with Titan in the am and it’s incredible, coming into 10 weeks and have got my weight from 175 to 190 and bench is steady climbing. Couldn’t be any happier with the results so far. Definitely a customer for life !!
This stuff taste like shit however it works and if your goal is to get inshape taste doesn’t matter. I recommend having your nutrition in check before using this💪🏽
I was skeptical at first, especially with the taste. At the end of my first cycle I noticed gains in my chest and more definition in my biceps. Coming into my second cycle and I'm noticing more strength and feeling fuller. Almost like a constant pump. I've recommended these supplements to others.
I’m going to be 43 in December. These products work and I have been taking them for a couple years now. I recommend them to everyone.
Works pretty decent
Day 8 and I can tell it's legit
Awesome
Stout taste lol. Good supplement
helps you get to where you want to be!!
Love it 6’0 255lbs 50years old
I feel better physically, stronger and more confident. It taste gross but I’m here for the gains. With that said it’s only been 12 days, I am excited to see the results in another two weeks
Ws lo mejor en 20 años de entrenamiento y ahora me siento y me veo muy diferente levanto mucho mas peso esto es genial
Belive what you read
Muscle Growth and Size difference 👍🏼
Fantastic, a work amazing, faster, can’t believe it, my body is shifting to the better very happy with results. Only 6 days, that’s the true 100%.
one pic is 7 months of dieting and training and the other is after 1 month,so far on Rad Mass.
Just right down good stuff !! Thanks VM!
This stuff is the bomb love it definitely work I'm 45 never had arms this big 💪
I’m 58 and had not been working out for about a decade. Massive work stress, high cortisol levels, sketchy diet, not enough exercise, no sustained physical labor, no weights… but moderately healthy and active. Started getting back into fitness over the last three years. My mass, strength, and endurance that I had built up into my late 30’s stayed level into my 40’s but was hit hard with some physical injuries and health issues. Got it turned around but didn’t get back into my physical routines to be at my peak. Over the last three years, I have been carefully getting back into shape, methodically making meaningful gains. It was imperative to avoid injuries yet make gains. I travel for my business and have limited time. It’s been a year now that I’ve been lifting when weights are available and exercising on the regular but hit a plateau of sorts till I started your products. Started using your products (Rad-Mass) for two months now and ready to cycle off. I should be able to keep the gains and the momentum with exercise and nutrition, then start back up again with your supplements. Rad-Mass helped me bust through the plateau I was having and now hitting heavier weights, longer hikes, faster speeds, and shredding fat. My physical activity mostly consists of body weight/ resistance training daily, ruck marching (military style hikes) a few miles with weights 15-120lbs/ 3.25-20 kilometers over alternating elevation terrain) once to twice a week, running 3K-7K twice a week, and some iron work during the week. It’s simple and efficient for my fitness goals. Let’s just say, I seem to be transforming back about where I was in my early 50’s right now with the goal to be in my 30’s when I was at my peak doing much the same thing I’m doing now. I think my strategy will have a synergy effect with my gains over time.
Slow start to seeing the gains but have seen some
I started using Vintage Muscle a few months ago after trying countless supplements over the years. Honestly, nothing has worked for me like Vintage Muscle. I’ve noticed a real difference in how I look, but even more impressive is the strength I’ve gained. After being stuck on a plateau for years, I’m finally lifting heavier and seeing consistent progress again. I’m excited to see where I’ll be in the months ahead!
These products continue to impress me.
Great product
I’ve been taking rad mass stacked with methyl-test for going on 3weeks. At the end of week 2 I began to notice measurable improvements in strength and endurance. According to my metrics I’ve made about a 20% improvement in overall strength. I’m starting to notice physical changes that I can visually see. Great product I will definitely be using for the long haul. This is my first attempt at using this product I’m on a 12 week journey. After I PCT I believe I will be stacking with other products potentially myo-11. As I progress I will send periodic updates. Thanks Ventage for giving me the drive I thought was lost.
tried this today and during lifting & now i can’t remember was it 380lbs or 400lbs. or somewhere in between , definitely a change
Great products! Real people, real company, not some scammer onTT. My 4th week tomorrow on Rad Mass, Hydroxygen, GH Trop, Myo 11, and Uronabol. Diobol gummies too!
Love the new 2oz bottles got this before and I loved it so I want to keep it in stock
Vintage muscle is hat off great company and awesome results.
It’s working fast and well would recommend to anyone looking to put on size pretty quick!
the stack is firming up the muscles and allowing me to push harder'd to bigger lifts
If you’re looking for your next step this is it
Finishing up week 2...definite notices in strength
Gives me a boost through out th day . My recovery is quicker
Words can't describe how I love vintage muscle supps they've definitely helped me reach my goals
I've only been taking it for about 4 days but I feel like it's working. I hit two new prs this week and my body is starting to feel harder and leaner than before.
Honestly I’m overly impressed with this product.
Just 1 month in and already seeing insane results
Always been a skinnier guy, but I gained 3 pounds within a week and shredded through all but one PR in the gym. Great product, taste is funky but mix it up with OJ and its good to go.
The product is great in my opinion. There has been a significant difference in my development since starting the product. My stamina and endurance has increased, I can just keep going, the recovery you get from the product keeps you going.
"If My Products Don’t Build You Up, We Don’t Want Your Money."
If Vintage Muscle doesn’t help you get stronger, harder, and more powerful within 30 days of daily use, we don’t want a dime from you.
We’re confident because these formulas work. They’ve already transformed thousands of men.
But here’s the truth — nothing works for everyone. And if it doesn’t work for you, we’ll refund you. No excuses.
