How you get it differs by row, and the standing chip says which: a retail pharmacy where a
 branded form exists, a compounding pharmacy on a clinician's prescription for most of the
 rest, and no lawful US supply at all where the chip says there is no pharmacy route. What the
 research shows, and what it does not, is on each guide.

## No provider we've verified carries any of these yet

None of the 4 cognitive & mood compounds we cover is published by
 any of the licensed telehealth providers we track. That is the honest answer, and it
 changes as compounding status changes.

### Tell me when that changes

## From consult to results

**01 Consult** A licensed provider reviews your goal, history, and labs before any protocol is offered.

**02 Protocol** If appropriate, a compounding pharmacy prepares the peptide; your provider sets dose and duration.

**03 What changes** Response windows vary by peptide and by person. Each peptide page states what the published evidence reports.

## Questions about cognitive & mood peptides

### Are cognitive & mood peptides FDA-approved?

Status varies by compound and is described per peptide on its own page. Most are dispensed as compounded preparations rather than FDA-approved products.

### Do I need a prescription?

Yes. These are obtained through a licensed provider and a compounding pharmacy.

### How long until I notice anything?

Onset varies by peptide — each peptide page gives what the studies report.

### How do I find a provider?

Open ProviderMatch: it shows which providers sell the compound for your goal, what each one charges to start, and what they publish about your state.
