You should be skeptical.
You have bought supplements that promised size and changed nothing. Read what three verified RAD-MASS buyers wrote.
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!

At 65 putting on muscle becomes more of a challenge but this is really helping!

The problem
Three walls block the size you should see.
“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
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. 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
Feel it
Buyers write about stronger lifts and harder pumps first.†
Weeks 6–8
See it
Judge your chest and arms at rest after bottle 2. Strength shows before size.†
-
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
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
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 kits 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 compete in a drug-tested sport or serve in the military.
- You are under 21, or you have a liver, kidney, heart, or prostate condition.

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: Both kits below include Arimidione and Cycle Support for all 4 weeks of PCT.

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?
Pick Subscribe & Save in the options above. It sends a bottle every 4 weeks at $65.99, so two shipments cover one 8-week cycle.
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 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 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, 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.
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, 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 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.”

Great
Will use again
This stuff is a game changer. 💯 works
I love Rad. Been out for a while. Back now and looking forward to growth.
Excellent
So far so good, I haven’t really seen any drastic changes since I started my cycle about 2 week ago, but I have noticed changes in my sleep and also in my recovery. I was able to add 15 pounds to my max bench within such a small period of time. I believe this is a good product and if you guys are looking for better recovery and more strength this is definitely a good option.
Works great makes me feel energized
Been using it for about for about week and a half and already have noticed a difference in strength and recovery time.
I weigh 194 an work out often can't seem to reach 200 with just muscle I stay same size my goal I'd liked 220 atleast but it's been a week or so an iv gains 2 pounds 💪
Not bad for 72-year-old who started exercising three years ago. Visceral fat from 12.5 to 9.8 while building muscle. This was stuff that got me started on a journey I’m enjoying thoroughly.
Good for vascularoty
Feels good never sore and fast process
Day 60
Definitely enjoying the pumps
Works did not think it would ar first but yes it does work
Awesome mass gainer love it will keep buying
Been using a month and have noticed exceptional fat loss and muscle gains
I've noticed results my first week, i feel stronger and I have gained mass
Good product
Good pumps, and great sleep
Fricking powerful
Gained 13 pounds within 3 weeks !! Great products , i workout 5 to 6 days a week with Also a good diet and muscle tech protein powder mass gainer !
Works great
I admit I was skeptical, and the taste is as bad as advertised. But this stuff works! Instead of dragging myself to the gym, I actually look forward to it and find myself pushing to add weight and sets to every workout! My vascularity has improved as well as muscle hardness.
The drops is very good, the pills give me shellfish reaction, I want the pills exchange
Increased vascularity, definition, and strength. Also, feel great and have more energy!
The best!
So far it’s been a week since I’ve started Rad mass and I’ve noticed the energy and noticing it when lifting as well.
Works great gets me jacked
It works
I’m a frequent gym goer and have taken probably too many things but this product works! It’s fast acting, my work outs became more efficient, my recovery seems to be about the same but with significantly more soreness. I have gone from 206 to 210lbs and currently still on so I don’t know how much mass will hang on once I’m off but I will follow every step like taking a steroid cycle and see what happens. So far, only week 2, this product simply works as advertised.
Thank you i can feel the the progress
I've seen some progress I'll try it for another month
Love it
Works amazing!
Ok never ran a 90 day cycle in the process of running one now with Rad mass started 2nd bottle strength has increased alot results are coming in ,more muscle less fat, I really recommend a 90 day cycle verses a 30 cycle. Better results for sure.
So far so good
Love this stuff. Great pumps on this stuff
Great so far !
