Dihexa for Research

What is Dihexa?

Dihexa is a synthetic peptide derived from angiotensin IV, studied for its reported high potency in promoting synaptic connections (synaptogenesis). The literature describes it as extremely potent relative to BDNF in model systems, with limited human data.

How Dihexa works (research mechanism)

Dihexa research focuses on the hepatocyte-growth-factor / c-Met system and synaptogenesis, with interest in memory and cognition endpoints.

Primary research applications

Synaptogenesis research

Studied for formation of new synaptic connections in models.

Memory and cognition research

Examined for learning and memory endpoints.

Neurodegeneration models

Used in exploratory neurodegeneration research.

Research dosing reference

Research references commonly cite 5-10 mg daily in 4-8 week cycled windows. Reference values only - an advanced compound with limited data; use caution.

Reconstitution & handling

Dihexa ships as a lyophilized (freeze-dried) powder and must be reconstituted before use in any liquid research model. Allow the vial to reach room temperature, swab the stopper, then add bacteriostatic water slowly down the inside wall of the vial - never spray it directly onto the powder. Swirl gently until dissolved; do not shake, as shaking foams the solution and stresses the peptide. The volume of water you add sets the concentration: a 5 mg vial reconstituted with 2 mL yields 2,500 mcg/mL, so 0.1 mL measures 250 mcg. A correctly reconstituted Dihexa solution is clear; discard if it is cloudy or shows particulate.

Storage & stability

Store un-reconstituted Dihexa vials refrigerated and protected from light for long-term stability; the lyophilized form is robust and tolerates shipping. After reconstitution, refrigerate at 2-8C, keep away from light, and use within the typical research window of roughly two to four weeks. The benzyl alcohol in bacteriostatic water helps inhibit microbial growth across that period. Always label reconstituted vials with the concentration and date.

Common research pairings

Generally studied as a standalone high-potency nootropic.

How Dihexa compares

Dihexa is studied as far more potent than Semax/Selank in model systems but with much less data, making it a specialized research tool.

Safety & research considerations

Dihexa is a research chemical with limited human data and is not approved for human use. For laboratory research only - handle with caution.

Sourcing, purity & Certificate of Analysis

Every lot of Dihexa sold by Peptides Factory Direct is third-party tested to a 99%+ purity target, with identity confirmed by mass spectrometry and purity quantified by HPLC. A Certificate of Analysis (COA) documenting these results is available on request and ties each vial to a tracked lot. Material ships nationwide to all 50 US states with cold-chain handling where appropriate and fast domestic dispatch. This documentation is what separates research-grade Dihexa from unverified material - quality is established before the vial ever reaches your lab.

How to order Dihexa for research

Dihexa can be ordered through the Peptides Factory Direct research portal as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months). Checkout requires confirming you are 21 or older, purchasing for laboratory research only, and that the product is not for human or animal consumption. Bulk and standing-order pricing is available - note it in your order. Open the order portal to view current research sizes and pricing.
