Acacia berlandieri.
A borderland shrub whose leaves carry phenethylamine-type amines. They work by nudging your own stored catecholamines out, which is why it turns up in stimulant blends.

What Acacia berlandieri is, and what it does.
- Does it work
- Suits people who want a short herbal lift before training. Alkaloid content swings with season and site, so a standardised extract tells you more than a leaf powder does.
- How much to take
- No dose figure is on record. Leaf alkaloid content shifts with rainfall, season and plant part, so a standardised amine figure is the number worth reading.
- Time to feel it
- On a batch carrying real amine content, the lift arrives inside 30 to 60 minutes and fades fast, because these amines are broken down quickly.
- The first dose
- Day one is a short, mild stimulant feeling within the hour on a potent batch. On a weaker batch the day passes quietly.
- With regular use
- Nobody has measured weeks of daily human use. What's known long-term comes from grazing livestock, where heavy sustained browse caused reversible movement problems.
- How well tolerated
- This is a stimulant-class plant with real cautions. Monoamine oxidase inhibitors are a hard no alongside it, and anyone on heart or blood pressure medication should ask a doctor.
- How it feels
- A brief, clean-edged alertness on a potent batch, lighter than coffee and shorter. It usually fades within an hour or two.
- The overlooked benefit
- Its main amine is broken down fast by monoamine oxidase, which is exactly why anything slowing that enzyme, medicine or herb, turns a mild effect into an unpredictable one.
The proof, claim by claim.
These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
Indirect sympathomimetics work by pushing stored catecholamines out of nerve terminals rather than by making new ones. Tyrosine is the upstream substrate for that pool through the tyrosine hydroxylase step. Pairing them is a substrate-plus-releaser logic, which is mechanistic rather than clinically demonstrated for this plant. No human study has tested the combination.
Theanine does not block sympathomimetic amines, but it shifts the subjective texture of stimulation toward less jitter. Formulators use it beside stimulant botanicals for that reason. It does not lower the cardiovascular load, so it should not be read as an offset. The effect is on how the stimulation feels, not on what the amine does to vascular tone.
St John's wort raises synaptic monoamine availability through reuptake and enzyme effects. Adding a releasing amine on top pushes the same pool from the other end. That is a recognised reason for caution with any indirect sympathomimetic, not a benefit to seek. The pairing is flagged here as an anti-synergy.
Dietary nitrate raises nitric oxide availability and tends to relax vessels. A sympathomimetic amine pushes the other way through adrenergic vasoconstriction. The net blood pressure effect of the pair is not predictable from either component. Read the interaction as directional conflict rather than as a smoothing agent.
Nothing specific on file for Acacia berlandieri. Match the label to the daily amount above, and tell your doctor what you take.

These phenethylamine-type compounds are broken down quickly by an enzyme in the body, which is why taking them by mouth gives short and unpredictable exposure.
The alkaloid content in browse plants like guajillo shifts with season, plant part, rainfall and growth stage, so a leaf powder is a variable input rather than a fixed, predictable dose.
Acacia berlandieri leaf contains phenethylamine-type compounds that act indirectly on the nervous system by displacing stored catecholamines from nerve endings.
Veterinary literature on grazing animals has long linked heavy guajillo browsing in small ruminants to a reversible loss of hind-limb coordination, attributed to the plant's amine content.
Where Acacia berlandieri comes from.
A thorny shrub from the Texas and Mexico borderlands. Its leaves contain natural stimulant amines, and how much you get depends heavily on when and where the plant was picked.
Made from a plant. What ends up in the capsule tracks the harvest, so batch testing and a stated marker matter more here than with a made molecule.
