Description
Pure Rawz Synephrine solution is a bitter orange protoalkaloid (p-synephrine), available as a powder. Each batch is checked for 99%+ purity. It’s intended for research use only.
Synephrine solution explained
Synephrine, or p-synephrine, is the main protoalkaloid in bitter orange (Citrus aurantium). It’s sold here as a liquid solution.
It replaced ephedrine in many weight-loss supplements after ephedra was banned in 2004.
Mechanism of action
p-Synephrine binds beta-3 adrenergic receptors, which drive fat breakdown, and binds alpha and beta-1/2 receptors only weakly. That’s why it has less heart effect than ephedrine.
The m-synephrine isomer, phenylephrine, acts quite differently.
Published Synephrine solution research
Stohs and colleagues have reviewed its effects, reporting small increases in metabolic rate and fat burning with little effect on heart rate at studied levels.
It’s on the WADA monitoring program.

This listing is 20g of powder for $32.22.
Powder suits labs that want to make their own solutions or capsules. Weigh it on a milligram scale.
Using Synephrine solution in the lab
Labs testing exercise-mimetic compounds often compare a sedentary treated group with an exercised control group. That shows how close the compound gets to the effects of training.
Keep diet, housing temperature and activity the same between groups, since all three change metabolism on their own.
Record the time of day you dose and test. Several of these compounds act on the body clock, and timing changes the result.

How we test each batch
We test each batch for identity and purity before it ships, using HPLC and mass spectrometry, with independent third-party checks on top of our own.
The batch number on the label matches the certificate of analysis. If your lab keeps paperwork on file, ask us for it and we’ll email it over.
How to store Synephrine solution
Keep the container sealed at room temperature, away from heat, moisture and sunlight. Note the batch number and the date you opened it in your lab records.
Handling notes
Treat it as a lab chemical. Gloves and safety glasses are the minimum, and a clean, uncluttered workspace cuts down on mix-ups.
Store prepared solutions apart from untouched stock, and record who mixed what and when.
Before you start
- a milligram scale, since powder has to be weighed
- a suitable solvent if you’re making your own solution, such as DMSO or propylene glycol
