Every label in this category promises intensity.

You’ve seen it all before—loud claims, recycled blends, and “next-level” energy.

But does Stim Shady actually back up the hype, or is “smooth” just the latest buzzword?

Stim Shady by Frenzy Labs is not your typical stim bomb.

Instead of chasing chaos, this one aims for serious urgency—minus the usual anxiety.

Rare stimulants like DMBA and DMHA headline the formula, but there’s no alpha yo or yohimbine to derail your focus.

Pumps actually show up, and energy kicks in fast.

Still, this is a product for seasoned pre-workout users, not for first-timers or party-chasers.

Citrulline 6g

Pumps aren’t just an afterthought here.

You get a legit six grams per scoop, enough to feel a difference before you’re halfway through your first set.

If you’re after that full, swelling muscle pump, this is a real dose—not a sprinkle.

Beta Alanine 3.2g

Here’s where the tingles kick in.

This is the tried-and-true clinical dose for endurance, and you’ll feel it.

If you’ve ever felt your face start to buzz before a heavy lift, you already know the drill.

Glycerol Monostearate 3g

You want muscle fullness that sticks around?

Three grams of glycerol pulls water right into your muscles, turning every set into a visual pump session.

This is for lifters who want to look and feel pumped—not just dry veins.

Caffeine Anhydrous 375mg

This is where it gets serious.

You’re stepping into stim junkie territory here, so go easy if you’re not used to high caffeine.

One scoop delivers enough urgency for even the toughest sessions.

Alpha-GPC 50% 300mg

Focus doesn’t get left behind.

Alpha-GPC (yielding about 150mg) puts nootropic support on the table, so you stay dialed in when the energy hits.

You may not notice it alone, but in this stack, it ties the formula together.

Lion’s Mane Extract 300mg

Mental clarity gets another boost here.

Lion’s mane isn’t always seen in hardcore formulas, but here it adds to the alertness without overdoing it.

The exact standardization isn’t listed, but it rounds out the nootropic support.

4-Amino-2-Methylpentane (DMBA) 200mg

Here’s the wild card.

DMBA brings urgency and that “let’s go now” edge to the mix.

Tolerance goes up fast, so don’t make this your daily driver.

If you want a session that feels special, this is what does it.

2-Aminoisoheptane (DMHA) 100mg

Not just a supporting act.

DMHA adds another layer of mental energy, with a kick that’s strong but not overwhelming.

No DMAA here, but you’ll get that extra gear.

Theobromine 100mg

No roller coaster ride.

Theobromine smooths things out and keeps your mood steady.

It keeps the edge from getting too sharp.

Methyl Synephrine HCL 25mg

Brings a bit of thermogenic heat and a background boost.

You won’t feel it stealing the show, but it helps keep energy high.

The secret sauce?

No alpha yo, no yohimbine, and none of the harsh side effects that usually show up in the strongest pre-workouts.

This formula is all about urgency and focus—energy you can actually control.

DMBA and DMHA make their presence known, but the ride stays smooth from start to finish.

If you’re used to formulas that trade power for chaos, this one goes another direction.

You’ll feel the lift hit quickly—energy builds fast, but it’s clean.

No shaky hands, no racing heart, and no anxiety as the session kicks in.

Focus actually sticks around, and the physical drive doesn’t fade.

The pumps show up strong, helped by both citrulline and glycerol.

Instead of a crash, you stay in the zone from start to finish.

Snow cone flavor is sweet without being overpowering.

Mixes up with no clumping or grit, and goes down easy.

No need to brace yourself for a chemical aftertaste.

Pros:

• DMBA and DMHA for real urgency without the chaos
  
• No alpha yo or yohimbine, so anxiety is off the table
  
• Pumps that actually deliver, even in a stim-heavy formula
  
• Easy to mix, sweet flavor, and solid focus
  

Cons:

• Too much for beginners or anyone sensitive to stimulants
  
• Alpha-GPC dose is modest, focus is noticeable but not extreme
  
• DMBA tolerance ramps up quickly—don’t use it daily
  
• Not for party pre fans or those chasing euphoria
  
• Only a couple of flavors to choose from

Perfect for experienced pre-workout users who know their tolerance.

Best if you want urgency, focus, and pumps, but hate the alpha yo jitters.

Anyone looking for a productive, driven workout session without wild mood swings.

Not ideal if you’re new to stims, want a daily formula, or crave heavy euphoria.

Skip it if you want dry, veiny pumps—this is for those who like that full, “wet” look.

Scoop carefully—actual weight is heavy, so level off for a proper serving.

Take 20 to 30 minutes before your workout, ideally on an empty stomach.

Never combine with other stims or fat burners.

Use only when you want a truly urgent session—don’t burn out your tolerance.

Stim Shady by Frenzy Labs carves out a real spot in the 2025 high-stim lineup.

You get rare stimulants, a proper caffeine punch, and zero alpha yo side effects.

If you want urgent, productive energy that doesn’t wreck your mood or crash your session, this is one of the few that can actually deliver.
