Transparent Labs Stim-Free is a specific caffeine-free pre-workout in the brand’s PRE series. The current Strawberry Lemonade panel provides a useful reference for comparing it with other non-stimulant powders. This is a label-based guide; it does not include hands-on taste, mixability or workout testing.
What the current label contains
The manufacturer’s Strawberry Lemonade panel lists one 20.8 g scoop and 30 servings per container. Selected amounts per serving are:
- Citrulline malate 2:1: 8,000 mg
- Beta-alanine: 4,000 mg
- Betaine anhydrous: 2,500 mg
- Taurine: 1,300 mg; L-tyrosine: 1,000 mg
- elevATP: 150 mg; Senactiv: 50 mg
- BioPerine: 5 mg; huperzine A: 100 mcg
The panel also lists 150 mg sodium and 100 mg potassium. The official product page identifies the formula as stimulant-free. Check your chosen flavor and container, since packaging and serving weights can change.
Caffeine-free still calls for a full-label review
Eight grams of citrulline malate is the weight of the combined ingredient, so it should not be compared one-for-one with eight grams of pure L-citrulline. Likewise, the absence of caffeine does not make every other ingredient irrelevant to medications, personal tolerances or existing supplements.
Beta-alanine can cause tingling. Its proposed training benefits are studied with repeated use over weeks; feeling a sensation after one serving is not evidence that the finished product improved a workout. The NIH evidence overview describes mixed results across exercise settings. Ingredient research also does not establish that this exact multi-ingredient formula will deliver a particular result.
How to decide whether it fits
Start with your reason for considering it: reducing added caffeine, choosing disclosed ingredient amounts, or avoiding a late-day caffeinated drink. Then compare the actual serving rather than the size of the tub or a front-label claim.
- Calculate cost using 30 labeled servings for this version.
- Check for overlapping beta-alanine, betaine and other ingredients in your routine.
- Review the complete warnings and ask a qualified clinician about medications or health conditions.
Removing a caffeine serving may be useful for a particular routine, but it cannot promise uninterrupted sleep, better recovery or a stronger session. Nutrition, training and adequate rest remain the foundation.
