Common questions
Is 3.4 fl oz TSA-friendly?
Each bottle is 3.4 fl oz (100 mL), which matches the common travel-size liquid limit. TSA rules can change, so follow current TSA 3-1-1 guidance and the screening instructions at your airport.
Can I toss it in a gym bag or a pocket?
Yes. 3.4 fl oz is pocket-size: gym bag, carry-on, jacket. 23g of complete protein, no shaker, no powder. Keep the cap closed, as you would with any liquid.
Do I still have to follow TSA rules?
Yes. We size the bottle at 3.4 fl oz so it can fit typical carry-on liquid limits, but you are responsible for following current TSA rules and any airline or airport instructions.
