Description
Dihexa capsules give you 60 pre-measured capsules, each with 5mg Dihexa, so there’s no powder to reconstitute and nothing to weigh.
Dihexa capsules contents
- Dihexa: 5mg per capsule, 300mg per bottle
Capsules take out the measuring step. Each one carries a fixed amount, and the totals above show what a full bottle of 60 adds up to.
Dihexa in brief
Dihexa is a small peptide-like compound from Washington State University, based on angiotensin IV. It acts on the hepatocyte growth factor (HGF) receptor, c-Met.
It was designed to cross into the brain.
Dihexa binds hepatocyte growth factor (HGF) and helps it pair up and activate its receptor, c-Met. In the brain, the HGF/c-Met system supports new synapses and connections between neurons.
It was built from angiotensin IV and tuned to be stable and to get past the blood-brain barrier. In rat models it increased dendritic spine growth, the physical sites where synapses form.
Why a capsule format?
Most published work on Dihexa used injection or cell culture, so oral delivery is its own research question. Capsules make that question easy to set up: the amount per unit is fixed and the bottle stays stable at room temperature.
Peptides taken by mouth face stomach acid and digestive enzymes, so oral and injected results aren’t interchangeable. If you’re comparing formats, run them as separate arms and keep notes on which one each result came from.

What the research says
McCoy and colleagues reported in 2013 that Dihexa improved memory in rats and boosted synapse formation.
There are no human trials.

How many bottles of Dihexa capsules?
Work out the total before you order. Count the arms in your study, the number of time points in each and the capsules each time point uses, then divide by 60. Rounding up by one bottle covers a repeat run or a spoiled sample.
Keep capsules from the same batch within one study if you can. The batch number is on the label, and matching it across arms removes one variable from your results.
Dihexa capsules purity and lab testing
We only sell U.S.-made products, and Dihexa capsules are no exception. Each batch is tested by an outside U.S. lab for identity, content and purity, with a 99%+ HPLC purity standard.
You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.
Purity isn’t the whole story, so batches are screened for endotoxins, heavy metals and sterility too. Write the batch number from the label into your notes so you can match results to the paperwork later.
How to store Dihexa capsules
Keep the bottle closed tight at room temperature or in the fridge, away from heat, light and moisture. Leave any desiccant packet inside. Capsules don’t need reconstituting, so there’s no mixed solution to use up.
