About This Product.

Transparent Labs Stim-Free Pre Workout is a caffeine-free pre-exercise formula designed for athletes who want to support training performance without stimulants. It contains beta-alanine, citrulline, and branched-chain amino acids (BCAAs) — a combination commonly used to address blood flow, muscular endurance, and muscle protein availability during exercise.

Citrulline is an amino acid studied for its role in nitric oxide production, which may support circulation and the delivery of oxygen and nutrients to working muscle. Beta-alanine buffers hydrogen ion accumulation in muscle tissue, which is associated with the burning sensation during high-intensity sets — it is studied for its potential to extend muscular endurance. BCAAs, particularly leucine, are linked to muscle protein synthesis and may help reduce exercise-induced muscle breakdown.

This formula suits athletes who train in the evening and want to avoid sleep disruption, those who are sensitive to caffeine, or anyone mid-cycle who needs a break from stimulant-based products. It also works well for two-a-day training sessions where a second stimulant dose would be impractical.

The Strawberry Lemonade flavour is specified in the product name. Transparent Labs is a brand known within the performance nutrition space for disclosing full ingredient quantities on their labels — a practice that allows informed dosing decisions and is rarer than it should be in this category.

Frequently Asked.

Why would I choose a stim-free pre-workout over a regular one?

If you train in the evening, are sensitive to caffeine, or are already consuming caffeine through other sources, a stimulant-free formula lets you support performance without disrupting sleep or adding to your overall stimulant intake. It is also practical for second sessions in a day.

Will I still feel a noticeable effect without caffeine?

Beta-alanine often produces a tingling sensation (paraesthesia) on the skin, which is a normal and harmless physiological response, not an indicator of efficacy. Citrulline may contribute to a muscle pump during training. The effects are more subtle than a stimulant-based product, but the underlying mechanisms are well-studied.

Is beta-alanine safe to take daily?

Beta-alanine is considered safe for most healthy adults at typical supplemental doses. The tingling sensation it causes is harmless and tends to diminish with regular use. If you have any underlying health conditions, check with a clinician before starting.

Can I take this alongside a caffeinated product?

Yes — because this formula contains no stimulants, it can be stacked with a separate caffeine source if you choose. However, monitor your total daily caffeine intake and avoid doing so close to bedtime.

Who should avoid this product?

Pregnant or breastfeeding individuals should avoid pre-workout supplements unless advised otherwise by a doctor. Those with kidney conditions should be cautious with high-dose amino acid products. Check the full ingredient list on the packaging if you have known sensitivities or are taking medication.

Finally a pre that doesn't wreck my sleep

4 months ago

Train after work most evenings so anything with caffeine just destroys my sleep. Been using this for about six weeks now and I genuinely notice the difference in my later sets — less of that burning sensation cutting things short, and I feel like I'm recovering between sets a bit faster. Strawberry lemonade flavour is actually decent, not too sweet. Mixes clean too.

Solid stim-free option

4 months ago

Switched to this mid-cycle when I wanted a break from my usual caffeinated pre. Wasn't expecting much honestly, but the pump and endurance were noticeably there. Does what it says.

Good product, pricey for the size

5 months ago

No complaints about performance — I get good endurance through my sessions and the tingles from beta-alanine are strong which tells me the dose is proper. My only gripe is £68.99 feels steep when the tub doesn't last as long as I'd like. Would still buy again but wish they did a larger size.

Perfect for evening sessions

5 months ago

I do two-a-days a couple of times a week and this has been a lifesaver for the second session — no way I'm having more caffeine at 7pm. Citrulline kick is real and I love that you can see exactly what's in it and at what dose. Transparent labelling is something more brands should do.

5 months ago

Started using this before my half marathon training block. Great for long easy runs where I don't need a stimulant hit but still want something to take the edge off fatigue. Strawberry lemonade is pleasant — not overly artificial tasting.

Stacks well with my morning coffee

5 months ago

I take this separately from my coffee so I'm not stacking stimulants, and it means I can still enjoy the pre-workout ritual without worrying about going overboard. Endurance during high-rep sets is noticeably improved. Flavour is good — proper lemonade tang.
