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!

“I put my name on NOTHING I don't believe in. Period.”
The problem
“The same stack that worked in my 30's isn't working as well in my 40's.”
From our new-customer survey, Jul 2026
You did the work, and your effort is fine. Food and training built your base. Three things keep the next layer of muscle out of reach.
01
You run the same program on the same food. Your numbers have barely moved in months.
02
The pump fades an hour after you rack the bar. At rest, your chest and arms look flat.
03
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
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
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
One bottle lasts 4 weeks, so a full cycle takes 2 bottles. You feel it first and see it later. Results vary with your training and food.†
Day 1
Start
Take your mirror photos and log your lifts. Start Cycle Support the same day.
Weeks 2–3

Buyers write about stronger lifts and harder pumps first.†
Weeks 6–8

Judge your chest and arms at rest after bottle 2. Strength shows before size.†
Weeks1–4
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
Same dose, same food. Bottle 2 is built for fullness that stays after the pump fades.†
Michael S.
The mass gains from this product are incredible, the strength gains are awesome as well, will continue to use this product as well

The difference
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
Basic stack + RAD-MASS
For more size support, pair RAD-MASS with 19-NANDRO. See the stacks below.

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.

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: You can run RAD-MASS for as long as 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
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.
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.
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.
Run one cycle at a time. Finish 4 weeks of PCT and 4 weeks off before you start the next one.
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.
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.
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.
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.
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.
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.
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, 51, 61, 65, and 72. 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.
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, even if you open it.
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.

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.”
Jared Van Yperen, Founder Vintage Muscle
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.
