Transparent Labs BULK is a named pre-workout supplement. The word BULK here identifies the formula, rather than a wholesale order or a requirement to buy several tubs. This guide covers the standard BULK product and its current Blue Raspberry label.
What one labeled serving provides
The official Blue Raspberry Supplement Facts panel lists one 20.8-gram scoop and 30 servings per container. Its main ingredients include 8 grams citrulline malate 2:1, 4 grams beta-alanine, 2.5 grams betaine anhydrous, 1.3 grams taurine and 1 gram L-tyrosine.
It also lists 200 milligrams PurCaf caffeine, 200 milligrams L-theanine, 50 milligrams theobromine, 50 milligrams Senactiv and 300 milligrams AlphaSize material standardized to 50% alpha-GPC. That last amount represents about 150 milligrams alpha-GPC, rather than 300 milligrams pure alpha-GPC.
Read ingredient forms accurately
Eight grams of citrulline malate is the combined ingredient weight. It is not eight grams of pure L-citrulline. Keep the listed ratio and form beside the quantity when comparing another label.
Beta-alanine can cause tingling, but that sensation does not measure the quality of a session. Its performance research concerns repeated supplementation, not simply whether a single scoop produces a strong sensation. Evidence for individual ingredients also does not guarantee a particular result from a finished blend.
BULK, BULK Black and creatine
Standard BULK and BULK Black are separate formulas. A review, sale listing or photograph for Black should not supply the caffeine amount for this product. Likewise, the current BULK label does not include creatine: decide whether a separate creatine supplement fits your routine without assuming it is already in this tub.
Compare cost per intended serving, not just container price. Check the exact flavor panel because scoop weights and other ingredients can differ. If sport testing matters, verify the specific product in the relevant certification directory rather than relying on branding alone.
Before using it
Follow your container’s directions, count caffeine from every source and avoid combining stimulant pre-workouts. Natural-source caffeine still affects caffeine exposure. Choose a serving and training time that do not compromise sleep, and seek medical advice about supplements if you take medication, have a condition, or are pregnant or breastfeeding.
