What's inside

One capsule holds three blends.

The label lists each blend total. It does not list the amount of each ingredient inside a blend.

Energy and Focus Blend

Caffeine anhydrous · Phenylethylamine HCl · Glucomannan (konjac root)

Caffeine and phenylethylamine lead the formula. Glucomannan, a konjac fiber, rounds out the blend. It is formulated to support energy, focus, and appetite control.†

40 mg per capsule

Thermogenesis Blend

Raspberry ketones · Yohimbe bark powder · Green tea extract (min. 50% EGCG)

This 40 mg blend adds raspberry ketones, yohimbe, and green tea extract. It is formulated to support thermogenesis.†

7 mg per capsule

Lipolytic Blend

Helps with my hunger throughout the day

How to take it

Take one capsule each morning.

Follow the label. Three rules cover it.

Morning

1 capsule

Take 1 capsule in the morning with a full glass of water.

Limit

2 a day at most

Never take more than 2 capsules in 24 hours. Take none after 4 PM.

Cycle

8 weeks on

Use it for 8 weeks at most. Then take at least 2 weeks off.

Go easy on caffeine: Start with 1 capsule. Skip other caffeine, like coffee and energy drinks, while you take it. Do not stack it with a high-stimulant pre-workout like VINTAG3D.

Bottle math: One bottle holds 60 capsules. At 1 a day, it covers a full 8-week run.

The fit

Who it is for (and who it is not).

This is for you if:

  • You are cutting, and your energy fades by mid-morning.
  • You fight hunger between meals on a diet.
  • You train early and want a sharper start to the day.†
  • You handle caffeine well.
  • You are 21 or older.

Chester S.

I used this four running, and also four my push ups in between while running my 4 miles. And it's good when hitting the weights. 240 lbs 5 times .aged 66.

May 2026

This is not for you if:

  • You are sensitive to caffeine or other stimulants.
  • You have high blood pressure, or a heart, thyroid, liver, or kidney condition.
  • You have anxiety, depression, or another mental health condition.
  • You take any prescription medicine. Talk to your doctor first.
  • You want to hold muscle on a cut. Look at Hydroxygenin.†
  • You compete in a drug-tested sport.
  • You are under 21, pregnant, or nursing.

About stimulants: You may feel warm, sweaty, or wired. Stop and call a doctor if your heart races or you feel chest pain.

Start My 8-Week Cut ↑

$27 for 60 capsules. At 1 a day, one bottle covers 8 weeks.

The plan is set. Now win the mornings.

Cuts break down in the slow, hungry hours of the day. CLEN-XT50 is built for those hours.†

Eat clean. Train hard. Take one each morning.

What CLEN-XT50 will not do

  • Replace your diet or training. It backs them up.†
  • Hold muscle on its own. For that, see Hydroxygenin.†
  • Run past 8 weeks. Take 2 weeks off after each run.

It is built to make cut mornings easier.†

Questions

Quick answers.

How do I take it?

Take 1 capsule in the morning with a full glass of water. Never take more than 2 capsules in 24 hours, and take none after 4 PM.

How much caffeine is in it?

The label lists caffeine inside a 425 mg blend. It does not list the caffeine amount alone.

Start with 1 capsule, and skip other caffeine while you take it.

How long can I run it?

Up to 8 weeks in a row. Then take at least 2 weeks off before you start again.

Can I take it with my pre-workout?

Do not stack it with a high-stimulant pre-workout like VINTAG3D. A stim-free pump formula like NITRIC-OX50 is a better match.

Can I take it on a cycle?

Yes. CLEN-XT50 holds no prohormones, so it adds no PCT of its own. Talk to your doctor if you take any medicine.

Will it show up on a drug test?

It holds no prohormones, but it does contain stimulants. If you compete in a tested sport, show the label to your league first.

Is it vegetarian?

No. The capsules are gelatin.

I am over 50. Is it for me?

Check with your doctor first, since stimulants raise your heart rate. If your doctor agrees, follow the label.

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. Keep your creatine and protein. Skip other stimulants, and talk to your doctor if you take any medicine.

The cut is yours to finish. Start tomorrow morning.

Why trust us when every other supplement brand has lied to you?

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.”

"If My Products Don’t Build You Up, We Don’t Want Your Money."

"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.
