transparent labs pre workout vs gorilla mode for energy review

Who This Is For (And What I'm Solving)

You're standing in the supplement aisle (or scrolling tabs) trying to pick between two heavy hitters: Transparent Labs Bulk and Gorilla Mode. Both promise insane energy. Both have huge followings. But they hit completely differently.

This review is for the lifter who wants real data, not hype. I spent 30 days cycling between the two, logging every rep, heart rate spike, and afternoon crash. I tested the Stim-Free versions too, but the focus here is on the energy-heavy formulas. You'll learn which one gives you clean, sustained drive versus a jittery spike.

Quick Summary:

• Who this is for: Intermediate to advanced lifters who need high-stim energy for heavy compound lifts or long sessions.
• Our top pick for raw energy: Gorilla Mode (Original) — 410mg of caffeine hits harder and faster.
• Our pick for clean focus: Transparent Labs Bulk — smoother ramp-up with no crash.
• Price range: Both sit between $39 and $55 per 30 servings. Gorilla Mode is slightly cheaper per serving.

Buyer's Guide: What to Look For in a High-Energy Pre-Workout

Before we dive into the head-to-head, here’s what I actually look for. Most people just stare at the caffeine number. That’s a mistake.

1. The Caffeine Source and Dose

Gorilla Mode uses anhydrous caffeine (fast-acting). Transparent Labs uses a mix of anhydrous and di-caffeine malate (slower release). At 200mg vs 410mg, you will feel the difference. If you're sensitive to stims, start with half a scoop of either.

2. Alpha-GPC and Choline for Focus

Energy without focus is just anxiety. Look for Alpha-GPC or Citicoline. Gorilla Mode packs a massive 600mg of Alpha-GPC. Transparent Labs uses 300mg of Cognizin (Citicoline). The Gorilla Mode dose is clinically shown to boost power output, but it can make you feel "wired."

3. Pump Ingredients vs. Energy Ingredients

Transparent Labs Bulk is more balanced. It has 4g of L-Citrulline and 2g of Beta-Alanine. Gorilla Mode has 9g of Citrulline Malate (a huge dose) but less focus on beta-alanine. If you want skin-splitting pumps with your energy, Gorilla Mode wins. If you want a clean, all-rounder, Transparent Labs is better.

4. Artificial Sweeteners and Dyes

Transparent Labs uses Stevia and fruit extracts. Gorilla Mode uses Sucralose. If you have a sensitive stomach, that matters. I had zero GI issues with Transparent Labs, but Gorilla Mode gave me a slight tingle and a "heavy" feeling if taken on an empty stomach.

The 30-Day Test: Transparent Labs vs Gorilla Mode

I ran this like a lab rat. Same time of day (4:30 PM), same meal (2 hours prior), same workout split. Here are the individual breakdowns.

1. Transparent Labs Bulk (Pre-Workout)

Price: $49.99 | Rating: 4.5/5 | Best for: Clean energy without the jitters

This is the "adult" pre-workout. The di-caffeine malate releases slowly. I didn't feel a "rush" — I felt a build. By minute 20, my focus was razor-sharp. I hit a 405lb deadlift PR on week 2 of this test, and I attribute that to the consistent focus rather than a sudden burst.

The downside? It lacks the explosive kick. If you're used to high-stim formulas, 200mg might feel weak. You'll need to double-scoop, which makes it expensive (nearly $100/tub). The Blue Raspberry flavor tastes like a light Gatorade — not too sweet, not bitter.

Pros: Transparent label (literally), no crash, no artificial dyes, great for afternoon workouts.

Cons: Lower caffeine dose, pricey per serving if you use 2 scoops.

2. Gorilla Mode (Original)

Price: $39.99 | Rating: 4.8/5 | Best for: Max energy and skin-splitting pumps

This is the sledgehammer. 410mg of caffeine hits you like a freight train at the 15-minute mark. My heart rate spiked to 145 BPM during warm-ups — that's high for me. The focus is unreal due to the 600mg of Alpha-GPC. I felt like I could stare through walls.

But it's not for everyone. The Gorilla Mode gave me a mild headache on days 2 and 3, likely from the high choline dose. It also has that classic "pre-workout itch" from Beta-Alanine, though less than other brands. The Mango Peach flavor is sweet and thick — almost like a juice concentrate.

Pros: Massive energy, huge pump (9g citrulline), great value per serving, clinically dosed ingredients.

Cons: Can cause jitters, hard to sleep if taken after 4 PM, sucralose may upset sensitive stomachs.

3. Transparent Labs Stim-Free (The Control)

Price: $49.99 | Rating: 3.5/5 | Best for: Evening lifters or caffeine-sensitive users

I tested this to see if the "energy" was just caffeine or something else. It's not. Without stims, the pump is good (5g Citrulline) but the focus is flat. This confirms that Gorilla Mode's energy comes mostly from the massive caffeine dose, not the proprietary blends. Skip this if you need a kick.

4. Gorilla Mode Nitric (Stim-Free)

Price: $39.99 | Rating: 4/5 | Best for: Pump chasers who hate stims

This one surprised me. It has 10g of Citrulline and Agmatine Sulfate. The pump is genuinely better than the original Gorilla Mode. But since this review is about energy, it only gets a 4/5. If you want the pump of Gorilla Mode without the shakes, this is your pick.

5. The Budget Alternative: MyProtein Pre-Workout

Price: $25.99 | Rating: 3/5 | Best for: Tight budgets

I include this to show the gap. It has 200mg caffeine and 3g Citrulline. It works, but the energy is short-lived (45 minutes) and the mixability is poor. It's the "corolla" to the "ferrari" of the other two. Not a bad choice, but you get what you pay for.

Comparison Table: Transparent Labs vs Gorilla Mode

FAQ: Quick Answers

Can I stack Transparent Labs and Gorilla Mode?

No. Don't mix them. You'll end up with 610mg of caffeine and a panic attack. Pick one.

Which one is better for cardio?

Transparent Labs. The lower caffeine dose won't spike your heart rate as dangerously during high-intensity intervals. Gorilla Mode is for lifting heavy shit.

Which tastes better?

Gorilla Mode (Mango Peach) is sweeter and thicker. Transparent Labs tastes more natural. It's personal preference.

Which one should a beginner buy?

Neither. Start with half a scoop of Transparent Labs. Gorilla Mode will ruin your tolerance fast.

The Bottom Line Verdict

If you want to feel like a superhero for 60 minutes and you're lifting heavy, buy Gorilla Mode. It's cheaper, harder-hitting, and the pump is unmatched. But if you value your sleep, have mild anxiety, or workout in the evening, buy Transparent Labs Bulk. It's the smarter, cleaner choice that gives you 80% of the energy with zero crash. For me? I keep Gorilla Mode for Saturday PR attempts and Transparent Labs for my Tuesday volume day. That's the honest answer.
