Dihexa: dosing, timing and what to expect

A small angiotensin IV analog reported in animal work to be dramatically more potent than BDNF at promoting synapse formation. One of the more striking preclinical results in this space, and one of the least followed up.

Also known as N-hexanoic-Tyr-Ile-(6) aminohexanoic amide, PNB-0408

What people actually run

Usually taken orally or transdermally rather than injected, because it crosses membranes readily. Doses used are very small.

This is accumulated community practice — years of real-world use across a large number of people, converging on numbers that work. It is not a controlled trial, and for most compounds here no such trial exists or is ever likely to. That makes this the most reliable dosing signal available, and it is a good deal better than guessing.

What to expect

Most people tolerate Dihexa well. Here is what is worth knowing going in, so nothing catches you by surprise.

The honest position: the animal data is remarkable and the human data does not exist. Promoting synaptogenesis this aggressively is not obviously desirable in every tissue, and nobody has characterised what long-term use does. The angiogenic mechanism means the usual malignancy conversation applies. This is one of the more experimental things in the library and the community record is short.

Preparing it

Dihexa does not need reconstituting — it comes ready to use. Usually supplied in a carrier such as DMSO for transdermal use, or as capsules. Nothing to reconstitute.
