¶ Red‑Flag Symptoms (Stop & Escalate)
Biohacking is optional. Serious symptoms are not.
This page is general information. If you think you are having a medical emergency, call emergency services.
¶ Emergency: Stop Immediately and Seek Emergency Care
¶ Possible heart attack
Common warning signs include chest discomfort/pain and discomfort in upper body areas (arms, back, neck, jaw, or stomach), shortness of breath, cold sweat, nausea, or lightheadedness.[1][2]
¶ Possible stroke
Watch for sudden numbness/weakness (especially one side), confusion/trouble speaking, trouble seeing, trouble walking/dizziness/loss of balance, or severe headache with no known cause.[3]
¶ Other emergency patterns (examples)
- Severe difficulty breathing
- Fainting or near-fainting with concerning symptoms
- Severe allergic reaction (swelling of face/lips/tongue, trouble breathing, widespread hives)
¶ Urgent: Stop the Experiment and Get Same‑Day Advice
- New palpitations with dizziness, chest pain, or shortness of breath
- Severe insomnia or agitation after starting a new stimulant/supplement
- Persistent vomiting/diarrhea with dehydration risk
- New neurologic symptoms (weakness, new severe headache, vision changes)
¶ Practical “Stop Rules” for Self‑Experiments
Before starting a new protocol/compound/device:
- Write down what symptoms end the experiment.
- Define what you’ll do if a key metric worsens (e.g., sustained BP increase, new anxiety, worsening sleep).
- Avoid multi-change stacks until you can reliably run single-variable tests.
