Most pre-workouts are built on caffeine and beta-alanine, and you feel both. This one is built on a mushroom: six extracts, each with its amount on the label, and no stimulant among them.
01Cordyceps carries the formula
1,650 mg of fruiting-body extract: two thirds of what is in the capsules.
02Green tea, without the caffeine
The extract is standardised to 98% L-theanine. The extraction leaves the caffeine behind.
03Ashwagandha, standardised
180 mg of root extract at 5% withanolides, which is 9 mg of them.
04Forty-five minutes before
Three capsules with water. Sixty capsules: twenty sessions.
Per three capsules, from the label. No health claim is authorised for cordyceps, L-theanine, ashwagandha, astragalus, rhodiola or grape seed, and none is made here. The capsule shell is gelatin: not suitable for vegans or vegetarians.
How to use it

FAQ
Questions, answered.
None. Not from green tea either — the green tea extract here is standardised to L-theanine, which is a different compound, and the extraction leaves the caffeine behind. If you want the stimulant, drink coffee.
No. The capsule shell is gelatin, which is animal-derived. It is not suitable for vegans or vegetarians. Everything else on the shelf uses HPMC.
Nothing. Cordyceps is a fungus and no fungus carries an authorised claim; EFSA rejected L-theanine; ashwagandha, rhodiola, astragalus and grape seed are botanicals, and the CJEU closed the on-hold route in April 2025. We can publish the composition and the doses. That is the whole permitted list.
Three capsules with water about 45 minutes before training. That is the label's own direction, not ours.
Sixty capsules at three a serving — twenty.
They are different products with different jobs and no shared ingredient, so there is no interaction between them to manage. If you are on medication, ask a pharmacist first — ashwagandha in particular is worth mentioning to them.
Anyone pregnant or breastfeeding, anyone under 18, and anyone on thyroid, sedative or immunosuppressant medication should speak to a doctor first because of the ashwagandha and astragalus.
