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.

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
