Terms of use

Stack is a personal protocol tracker and research tool. It surfaces literature-grounded information about peptides and research compounds to help you have more informed conversations with licensed healthcare providers. Stack is not a medical service, clinic, telehealth platform, or pharmacy.

Nothing on Stack — including compound pages, protocol suggestions, log interpretations, insights, or AI-generated output — constitutes medical advice, a diagnosis, a prescription, a dosing recommendation, or a sourcing instruction. All content is provided for educational and informational purposes only. You must consult a qualified, licensed healthcare provider before making any health-related decision.

Many compounds discussed on Stack have limited or no approved clinical use in the United States and other jurisdictions. Legal status varies by country, state, and intended use. Stack does not sell, source, or facilitate the purchase of any compound. It is your responsibility to understand the laws that apply to you.

Use of research compounds carries inherent risk including unknown long-term effects, drug interactions, and individual variability. By using Stack you acknowledge that you understand these risks and take full personal responsibility for any actions you take based on information found here.

Protocol data, daily logs, and journal entries are stored locally on your device by default. If you create an account, your data syncs to Supabase (supabase.com) using row-level security. Stack does not sell, share, or aggregate your personal health data. AI interpretation requests are sent to Anthropic's API (anthropic.com); Anthropic's standard privacy policy governs those transmissions. You can delete your data at any time from the settings page.

Stack is provided "as is" without warranties of any kind. We do not warrant the accuracy, completeness, or timeliness of any information. The literature summaries and AI-generated content may contain errors. Always verify with primary sources and qualified professionals.

These terms may be updated at any time. Continued use of Stack after any update constitutes acceptance of the revised terms. The effective date of the most recent version appears at the bottom of this page.
