Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Pre-Workout Caffeine Free Strawberry Lemonade by Gnarly Sports Nutrition
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This 6-ingredient pre-workout has branched-chain amino acids (BCAAs) — L-Leucine, L-Isoleucine, and L-Valine — which support muscle function. It also contains beta-alanine (sold as CarnoSyn), Citrulline Malate for blood flow, and Asian Ginseng Powder.
The rest is inactive stuff: natural flavors, stevia, citric acid, and a couple of flow agents.
Does it work?
Moderate evidence
Beta-alanine is possibly effective for athletic performance and physical performance — the evidence suggests it may help, but isn't definitive. The product doesn't contain caffeine, so you won't get a stimulant boost.
We don't have effectiveness data on file for the amino acids, Citrulline Malate, or the ginseng in this formulation.
How safe is it?
Well-documented data
Beta-alanine is generally well tolerated, but it causes a harmless tingling and flushing feeling (paresthesia) in most people — it usually starts on the scalp within 20 minutes and spreads to the body, lasting about an hour. The tingling is mild at lower doses and more noticeable at higher ones.
The safety data advises against using beta-alanine during pregnancy or while breastfeeding because there isn't enough information to know it's safe. We don't have safety data on file for the other active ingredients.
Meds to double-check
No known interactions
No interactions are documented for the ingredients we could check. Still, run your medications through the search tool on this page before you start — we don't have data for several of the other active ingredients.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
This is a decent choice if you're looking for a caffeine-free pre-workout to support athletic performance — no stimulant jitters. Expect the tingling feeling from beta-alanine; it's normal and harmless.
If you're pregnant, breastfeeding, or take any medications, check with your pharmacist first.
