Quick verdict

Bulk Black Lower caffeine, 4g beta-alanine, 30 full servings, theanine — a smaller, more restrained formula.
Gorilla Mode More caffeine, plus creatine and glycerol, higher betaine/tyrosine and a bigger pump/fullness emphasis.
Bottom line Bulk Black is the more restrained all-around high-stim option. Gorilla Mode is the more loaded choice if creatine, glycerol and formula size matter more.

My testing
Bulk Black has been tested firsthand. The current Gorilla Mode comparison is based on its current manufacturer label; I am not presenting the current version as a fresh side-by-side test.
Formula & Dosing
?
Gorilla Mode: more included ingredients by dose. Formula size is not a proven overall-performance advantage.
BULK BLACK
8G
Citrulline Malate 2:1
GORILLA MODE
10G
Pure L-Citrulline

Gorilla Mode includes creatine and glycerol alongside higher betaine and tyrosine amounts. BULK BLACK includes 4g beta-alanine, 200mg theanine and 200mcg huperzine A. The doses refer to the formulations compared here, not every historical tub.

Pumps & fullness
?
Gorilla Mode: larger L-citrulline amount. This is a label-based distinction, not a measured pump comparison.
Bulk Black
8g
citrulline malate 2:1 + 2.5g betaine
Gorilla Mode
10g
L-citrulline + 4g betaine + ~2.6g glycerol (HydroPrime)

Gorilla Mode lists 10g L-citrulline. BULK BLACK lists 8g citrulline malate (2:1), not 8g pure citrulline. Gorilla Mode also lists 4g HydroPrime at 65%, equivalent to about 2.6g glycerol.

Energy & Usability
BULK BLACK wins for lower caffeine: 325mg versus 400mg. Neither is a low-caffeine option.
Bulk Black
325 MG
Caffeine + 200mg L-Theanine
Gorilla Mode
400MG
Caffeine, no L-Theanine

The full-serving caffeine difference is 75mg. BULK BLACK also lists 200mg theanine; that does not guarantee a jitter-free experience.

Endurance
⚡
BULK BLACK includes beta-alanine; Gorilla Mode does not. This is not proof of an overall endurance win.
Bulk Black
4g
beta-alanine
Gorilla Mode
None
No Beta-Alanine

Bulk Black includes a full 4g beta-alanine dose. Gorilla Mode intentionally does not include beta-alanine.

Value
No fixed winner. Compare the live cost per full serving.
Bulk Black
30
Full servings
Gorilla Mode
20
Full two-scoop servings

Bulk Black gives 30 full servings while Gorilla Mode gives 20 full two-scoop servings. Current retailer pricing should determine which offers the better cost per full serving.

Pros & Cons

Bulk Black

Pros
More restrained, controlled feel
4g beta-alanine + dedicated focus stack
30 full servings
No artificial sweeteners/dyes
Cons
Smaller overall formula
No creatine or glycerol
325mg is still a lot for some

Gorilla Mode

Pros
Bigger, more loaded formula
400mg caffeine, 5g creatine, glycerol
Higher betaine and tyrosine
Strong pump/fullness emphasis
Cons
No beta-alanine
Only 20 full servings
Higher stimulant dose won't suit everyone
Who should choose each?

Choose Bulk Black if:

  • You want a more restrained high-stim feel
  • You want 30 full servings and 4g beta-alanine
  • You value a dedicated focus stack
  • You don't need bundled creatine

Choose Gorilla Mode if:

  • You want the more loaded formula
  • Creatine and glycerol matter to you
  • You want higher caffeine and pump emphasis

Skip both if:

  • You're caffeine-sensitive or new to stimulants
  • 400mg (Gorilla Mode) is too much for you
  • You usually train late
Final Verdict

Bulk Black for restraint; Gorilla Mode for a loaded formula.

Gorilla Mode is the bigger build — more caffeine, 5g creatine, glycerol, higher betaine and tyrosine. If you want a do-it-all loaded pre-workout and creatine bundled in, it makes sense.

Bulk Black is smaller but more controlled, keeps 4g beta-alanine, adds a real focus layer and gives 30 full servings. Both brands publish testing info, so that isn't the deciding factor — formula fit and how much stimulation you want are.

FAQ

Which has more caffeine? ▼
Gorilla Mode — 400mg vs 325mg. That's a meaningful stimulant-dose difference, not a rounding gap.
Does Gorilla Mode have creatine? ▼
Yes, 5g at a full dose. Bulk Black has none, so if you want creatine bundled in, that's a real Gorilla Mode advantage.
How much glycerol is in Gorilla Mode? ▼
4g HydroPrime powder standardized to 65% glycerol, providing about 2.6g glycerol — not 4g of glycerol.
Which is better for endurance? ▼
BULK BLACK includes 4g beta-alanine; the Gorilla Mode formula compared here does not. That ingredient difference alone does not prove which finished product improves endurance more.
Which is better tested? ▼
Check each product’s actual test reports and any batch-specific certification. Neither brand should receive an automatic testing winner without matching evidence.
