Not medical advice
Nothing inside Agonist — the peptide library, the reconstitution calculator, the dosing ranges, the protocol templates, the stacking checker, the journal prompts, the AI assistant if you use it, the export PDFs — constitutes medical advice, diagnosis, or treatment.
The information in the app is for educational and personal tracking use only. It is not intended to replace, override, or substitute for the judgment of a licensed healthcare provider who has examined you, knows your full medical history, and can monitor you over time.
Do not start, stop, or adjust any medication, supplement, or peptide on the basis of anything you see in Agonist without first consulting a qualified provider.
Research compounds
Many of the peptides referenced in the Agonist library are research compounds. They are not approved by the U.S. Food and Drug Administration, the European Medicines Agency, or any comparable regulator for human use outside of specific clinical trials. Some are approved in some jurisdictions and not others. Some are scheduled or controlled substances in certain countries.
You are responsible for understanding the legal status of any substance in your jurisdiction before purchasing, possessing, or using it. Agonist makes no representation about legality anywhere, and our inclusion of a compound in the library is not an endorsement of its safety, efficacy, or legality.
The doses, schedules, and protocols in the library reflect what has appeared in published research and in user reports. They are not prescriptions. They are reference points for conversation with a clinician.
No practitioner-patient relationship
Using Agonist does not create a doctor-patient, nurse-patient, pharmacist-patient, or any other healthcare relationship between you and Agonist, our employees, contractors, or advisors. We do not examine you. We do not review your records. We do not monitor you. We do not prescribe.
If a clinician, coach, or practitioner uses Agonist alongside their own clinical workflow, the relationship is between you and them, not between you and Agonist. They are responsible for the care they provide. We are not.
No endorsement of vendors
We do not link to peptide vendors. We do not recommend sources. We do not verify suppliers. Anywhere in the app or on this website where you might expect a source link, you will find nothing — that is deliberate.
The market for research compounds includes counterfeit product, contaminated product, mislabeled concentrations, inactive freeze-dried mass, bacterial contamination from improper handling, and worse. Independent third-party testing from a certified lab is the only way to know what is in a vial. Agonist does not perform that testing for you.
If you choose to obtain a substance, that decision is yours. The risks of obtaining a substance from any source are yours.
Information accuracy
We cite peer-reviewed sources where they exist — PubMed, ClinicalTrials.gov, manufacturer datasheets, and recognized pharmacology references. Where the published evidence is thin, we say so.
Even with citations, we cannot guarantee that the information in Agonist is correct, complete, or current. Research evolves. Mistakes happen. Half-life estimates differ between studies. Reported side-effect profiles are incomplete by definition. Do not rely on Agonist as the sole source of information for any decision about your health.
The reconstitution calculator performs arithmetic on the values you give it. If the values you enter are wrong, the output will be wrong. Verify every calculation against an independent source before drawing a dose.
Risks of self-administration
Self-administration of any injectable carries real risk. That includes, without limitation:
- Infection — local abscess, cellulitis, sepsis — from non-sterile technique, reused needles, or contaminated product.
- Inadvertent intravenous or intra-arterial injection of a compound intended for subcutaneous or intramuscular use.
- Nerve damage from incorrect site selection or needle depth.
- Severe allergic or anaphylactic reactions to peptides, excipients, preservatives, or contaminants.
- Downstream endocrine, metabolic, cardiovascular, renal, hepatic, or oncologic consequences that may not be detectable for months or years.
- Dose-calculation errors leading to underdose or overdose. Overdoses of certain peptides can be life-threatening.
Agonist does not eliminate any of these risks. A tracking app cannot.
Emergency care
Agonist is not for emergencies. If you are experiencing a medical emergency — chest pain, difficulty breathing, severe allergic reaction, loss of consciousness, suicidal thoughts, or any sudden severe symptom — call your local emergency number immediately.
- United States: 911
- United Kingdom: 999 or 112
- European Union: 112
- Australia: 000
- Elsewhere: your local emergency services number.
Do not wait for guidance from the app. Do not delay calling because you want to log something first.
Drug interactions
Peptides can interact with prescription medications, over-the-counter drugs, hormonal therapies, supplements, and with each other. The stacking-safety checker inside Agonist draws on published interaction data where it exists. The checker does not — and cannot — anticipate every interaction. Many peptide interactions are simply not well studied.
Before combining any peptide with another peptide, with a prescription drug (including but not limited to GLP-1 agonists, anticoagulants, insulin, thyroid medication, hormonal therapies, immunosuppressants, antidepressants), or with any other supplement, review the combination with a qualified clinician or pharmacist who has access to your full medication list.
Adverse events
If you experience any unexpected symptom, unusual reaction, or worsening of an existing condition while using a peptide — stop, and contact a qualified healthcare provider immediately. Do not wait to see if it gets worse. Do not rely on logging the symptom in Agonist as a substitute for clinical evaluation.
Symptoms that warrant immediate evaluation include but are not limited to: chest pain, palpitations, difficulty breathing, facial swelling, hives, persistent vomiting, severe headache, sudden vision change, severe abdominal pain, jaundice, dark urine, unexplained bruising, mood changes, suicidal thoughts, injection-site infection, fever following an injection.
Pregnancy & nursing
Do not use peptides if you are pregnant, trying to become pregnant, or nursing. Most of the compounds referenced in Agonist have no established safety data in pregnancy or lactation. The potential consequences for a developing fetus or nursing infant are unknown and may be serious.
If you become pregnant while using a peptide protocol, stop immediately and contact a qualified obstetric provider.
Mental health
Some peptides have documented or anecdotal effects on mood, anxiety, sleep, cognition, and appetite — including effects that can destabilize existing psychiatric conditions. If you have a history of depression, anxiety, bipolar disorder, disordered eating, substance use disorder, or any other mental health condition, talk to a qualified mental health provider before starting any peptide.
If you are experiencing thoughts of self-harm or suicide, contact a crisis service immediately. In the United States, call or text 988. Elsewhere, contact your local crisis line or emergency number.
Acknowledgment
Every time you use Agonist, you acknowledge that you have read, understood, and accepted this Medical Disclaimer in full. The first launch of the app presents this acknowledgment explicitly, and continued use of the app reaffirms it.

- Agonist is not liable for outcomes that result from those decisions. The limits in the Terms of Service apply.
- You are eighteen or older and are using Agonist for your own personal tracking only.
- You will seek qualified clinical care for anything that looks, feels, or registers as a medical problem.
If you do not agree with any part of this disclaimer, do not use Agonist. Delete the app. Close your account. We will refund any unused prepaid annual time on request to legal@agonist.app.
