Nitric-OX50

Stop buying fairy dust from GNC. I've seen 50-year-old men on this look better than guys half their age. No needles. No BS. Just results. I put my name on NOTHING I don't believe in. Period. ISYMFS.

What's inside
Two pump amino acids in four forms.
Every dose is on the label. Your body makes nitric oxide from arginine, and it turns citrulline into arginine. Nitric oxide is one signal that widens blood vessels during exercise.
800 mg, two forms
L-Arginine
L-arginine base 400 mg · L-arginine AKG 2:1 400 mg
Arginine is the amino acid your body turns into nitric oxide. It is formulated to support blood flow during training.†
400 mg, two forms
L-Citrulline
L-citrulline HCl 200 mg · L-citrulline malate 200 mg
Your body turns citrulline into arginine. It is formulated to support a fuller pump.†
80 mg per serving
Beta-alanine
Beta-alanine 80 mg
It is an amino acid found in many pre-workouts. The dose is small, so you should not feel a tingle.
15 mg + 36 mg
Niacin and calcium
Niacin 15 mg NE (94% DV) · Calcium 36 mg (as calcium carbonate)
Niacin is vitamin B3. One serving gives 94% of your daily value.
Stim-free: NITRIC-OX50 holds no caffeine or other stimulants. You can stack it with your pre-workout.
Erik L.
Great pump. Reminds me of the old school plasma jet
How to take it
Two capsules before a meal.
The label keeps it simple. Here is the routine.
Dose
2 capsules
Take 2 capsules once a day with a glass of water.
Timing
Before a meal
Take them 20 to 30 minutes before a meal.
Training days
Pre-workout meal
Make it the meal before your workout.
Dwight M.
It definitely a great product. I take this on heavy lifting days and get a huge pump! Goes really well with my preworkout and Myo-11 for real progress.
Bottle math: One bottle holds 60 capsules. At 2 a day, it lasts 30 days.
The fit
Who it is for (and who it is not).
This is for you if:
- You want more pump in your training.†
- You train late and want to skip caffeine.
- You take a pre-workout and want a stim-free pump add-on.
- You are 21 or older.
Mark R.
The pump on the N. O. booster is fantastic
This is not for you if:
- You want an energy kick. NITRIC-OX50 has no stimulants. Look at VINTAG3D.
- You take blood pressure medicine, heart medicine, or nitrates. Talk to your doctor first.
- You have low blood pressure or a heart condition.
- You are under 21, pregnant, or nursing.
About the pump: A pump is temporary. It fades in the hours after training.

You do the work. Let it show.
A full pump makes every set feel like it counts. Two capsules a day are built to help you get there.†
Train like it counts.
What NITRIC-OX50 will not do
- Give you an energy rush. It holds no stimulants.
- Build size on its own. A pump fades after training.
- Replace your training or your diet.
It is built to support blood flow and the pump while you train.†

Questions
Quick answers.
How do I take it?
Take 2 capsules once a day, 20 to 30 minutes before a meal, with a glass of water. On training days, make it your pre-workout meal.
Does it have caffeine?
No. NITRIC-OX50 holds no caffeine or other stimulants. You can stack it with your pre-workout.
Can I take it on a cycle?
Yes. It holds no prohormones, so it adds no PCT of its own.
Will it show up on a drug test?
It holds no prohormones or stimulants. If you compete in a tested sport, show the label to your league first.
Is it vegetarian?
The capsules are vegetable cellulose, and the label lists no animal ingredients.
Who should talk to a doctor first?
Anyone who takes blood pressure medicine, heart medicine, or nitrates. Anyone with a medical condition should ask first too.
What if it is not for me?
Your first bottle has a 30-day money-back guarantee. Email us within 30 days after delivery and send it back.
Can I keep taking creatine and protein?
Yes. NITRIC-OX50 fits with creatine, protein, and your pre-workout.
The work is already yours. Make it show.

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.”

Awesome products. Thanks VM .
I just started my second bottle of EQU-MASS and I feel more energetic and my workouts are intense. I've shed some stubborn fat and gain back some muscle mass. I feel great and I'm really happy with the product. Also NITRO-OX50 is great during workouts for an extra boost and pump.
My body never fails on my workouts .. I can always count on NITRIC..👍🏽
With this product ive notice more blood circulation throughout my veins and way better pumps in all my workouts
Gives a good pump!!
Veins be poppin
I love the pumps and transformations I am seeing from your products. Everything works so quickly and I couldn’t be happier!
I always have loved this is covers so many essential needs in your program
"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.
