Interaction warnings

Updated Oct 16, 2026 · Applies to Web, iPhone, and Android · All plans

When a question names a compound that may interact with a medication or health condition in your profile, ChatPEP shows a warning card above the answer. The card names the pair, describes the concern, and says what the research reports about it. Warnings are on every plan, and they cannot be turned off.

What a warning looks like

Each card has four parts:

  1. A level, from most to least serious: Safety Alert, Interaction Warning, Caution, and Note. Each level has its own icon shape, so it reads without color. A Note can simply record that no conflict is known.
  2. The pair, such as a compound and a medication, a compound and a condition, or two compounds.
  3. What is known about how the two may interact.
  4. The takeaway, in one line: what the research found about the pair, or that it has not been studied. A card never tells you to take, combine, time, or dose anything.

One card appears per pair in a chat. If the same pair comes up again later in that chat, the written answer still takes it into account without repeating the card, unless you ask for a check. Two peptides with only a minor note between them get no card; the written answer can still mention it.

When an answer has cards at more than one level, a row of tabs sits above them, one per level with its count, such as Warnings 2 and Notes 3. The most serious level opens first; select another tab to see its cards. When a level has more than three cards, the first two show, followed by a Show more button with the number of hidden cards, such as Show 4 more, so the answer stays in view. Warnings outside a chat, such as under Interactions on Today, are grouped the same way.

What ChatPEP checks

When your message names a compound or a blend, ChatPEP checks it against:

  • The medications and health conditions saved in your profile.
  • Alcohol, tobacco, and cannabis, when you turn them on under Also check against.
  • Medications you mention in the message, and conditions you say you have.
  • The compounds saved in My Stack, as the other side of the pair: a compound you name is checked against what you are running, but what you are running is not re-checked on every message.

Warnings still check your saved profile in a temporary chat.

If you mention in a chat that you take a medication, ChatPEP can add it to your profile and warn you in that same answer. See How ChatPEP updates your profile from a chat.

Check everything at once

In any chat, ask ChatPEP to check your medications, such as "Can you check everything I'm on?" ChatPEP checks the medications, health conditions, and substances saved in your profile against what is in My Stack and any peptide saved with your medications.

Each pair the research flags appears as a warning card above the answer, in the same stack as the answer's other warnings and once per pair. The answer says in a line what was checked against what, then what the research says about the pairs that matter. When no pair needs a card, no card appears and the answer says so.

To check one compound only, name it: "Check KPV against my medications." The check reads your saved profile, so it is not available in a temporary chat.

What a warning does not mean

  • No card does not mean no risk. ChatPEP warns only about interactions it knows about, and only for the medications, conditions, and substances it knows about you. With a substance turned on and no card, the research ChatPEP holds reports no interaction for that pair.
  • A card is not a diagnosis. It describes what is known about a pair. It is not a judgment about you.
  • It is research, not instructions. See Research only: what that means.

Talk to a doctor or a pharmacist before combining anything with a medication you take.

Keep your profile current

Warnings can only check what ChatPEP knows about you.

On the web

  1. Select your name at the bottom of the sidebar, then select Settings.
  2. Select Interaction warnings.
  3. Always checked shows your conditions, your medications and protocols, and My Stack. Select Medical conditions or Medications and protocols to change them.
  4. Under Also check against, turn on anything that applies.

On iPhone and on Android

  1. Open the menu and tap Settings.
  2. Under Personalization, tap Interaction warnings.
  3. Always checked shows your conditions, your medications and protocols, and My Stack. Tap Medical conditions or Medications and protocols to change them.
  4. Under Also check against, turn on anything that applies.

If a medication you take is not in the list, name it in your question. The answer can still discuss what the research says, even when no card appears. See Goals, conditions, and medications.

If a warning looks wrong

Select Report safety concern under the answer. You can also contact support with the compound and the medication or condition it names.
