Is PepStack medical advice?
No. PepStack is an educational research platform. All peptide profiles include evidence tiers and PubMed citations so you can make informed decisions with your healthcare provider. We use cautious language like "research suggests" because that's what the science supports. Always consult a qualified provider before starting any peptide protocol.
How are evidence tiers determined?
We use a 5-tier system: Tier 1 (FDA-approved), Tier 2 (human clinical trials), Tier 3 (preclinical/animal studies), Tier 4 (limited data, single research group), Tier 5 (theoretical). Every claim links to its PubMed source so you can verify the evidence yourself.
Do you sell peptides?
No. PepStack provides research-backed information, dosing protocols, and community knowledge. We do not sell, distribute, or recommend purchasing any peptide or research chemical.
Can I cancel my subscription?
Yes, you can cancel at any time from your account settings. You'll retain access through the end of your billing period.
What does a subscription include?
Subscribers get full access to detailed dosing protocols, drug interaction data, stacking compatibility guides, biomarker interaction analysis, and community insights for all peptide profiles. Free users can browse basic summaries and evidence tiers.
How often is the database updated?
We continuously review new PubMed publications and update peptide profiles as new research becomes available. Each profile shows its last-updated date.
