The verdict, fast
Transparent Labs Bulk The better default for most users โ€” 200mg caffeine, 30 full servings, 4g beta-alanine, 200mg theanine and a more manageable daily profile.
Gorilla Mode The stronger maximum-dose product. At two scoops: 10g pure citrulline, 5g creatine, 4g betaine, 4g HydroPrime glycerol powder (65%, ~2.6g glycerol), 5g tyrosine and 400mg caffeine.
Bottom line Choose Bulk when consistency and daily usability matter. Choose Gorilla Mode when a larger, more comprehensive maximum-dose formula matters more than scoop size, stimulant load or serving count.

These two sit at opposite ends of the design spectrum. Bulk is a clean, moderate, everyday one-scoop pre-workout. Gorilla Mode is a maximum-dose two-scoop formula built to throw everything at the wall.

The comparison basis: one full scoop of Bulk vs Gorilla Mode's maximum two-scoop serving. Gorilla's one-scoop and two-scoop data are kept separate โ€” it gives 40 lighter servings or 20 maximum servings, while Bulk gives 30 standard full servings.

Two label-reading cautions: Bulk's 8g is citrulline malate while Gorilla's 10g is pure L-citrulline (not identical citrulline content per gram), and both use 50% Alpha-GPC material, so the raw 800mg vs 300mg figures need the standardization explained.

Formula comparison based on current labels. Bulk has been tested personally; the current Gorilla Mode formula is compared from its verified label and is not presented as a fresh side-by-side experience test.

Bulk's 8g is citrulline malate; Gorilla's 10g is pure L-citrulline โ€” not identical citrulline per gram (Gorilla still wins the category). Both Alpha-GPC figures are 50% material: Bulk 300mg raw (~150mg active) vs Gorilla 800mg raw (~400mg active).
Formula versions checked: Transparent Labs Bulk (current 1-scoop panel) & Gorilla Mode (current 2-scoop panel)
Gorilla Mode at one scoop is roughly half these amounts across 40 servings. Bulk has 30 standard full servings; Gorilla has 40 one-scoop or 20 two-scoop servings โ€” don't read Gorilla as "40 full servings."
