Frequently asked questions
Quick answers about the site. If yours isn't here, email [email protected].
- Is this medical advice?
- No. The Biohacking Bible is an educational publisher. We summarise research literature and describe what published studies report. We do not diagnose, treat, prescribe, or provide dosing guidance. Always discuss changes that matter to your health with a UK-registered clinician.
- Why won't you tell me what dose to take?
- Two reasons. First, dosing depends on your medical history, medications, conditions, and goals — which a website cannot know. Second, many compounds discussed in biohacking are prescription-only medicines (POMs) in the UK, and providing dosing guidance for POMs without a prescribing context is outside our scope. Where we discuss compounds, we describe what the research used — not what you should take.
- What do the evidence grades mean?
- Each protocol is graded A through D based on the strength of human research behind it. A means multiple high-quality human RCTs converging; D means animal or anecdotal evidence with sparse human data. The grade is about evidence strength, not whether you should try the protocol. See our evidence-grading methodology for full criteria.
- Do you sell anything?
- No. We do not sell supplements, peptides, devices, courses, coaching, or services. We do not run affiliate links on protocol content. We do not accept paid placements or sponsorship for editorial pages. The site is free; we may add a newsletter or membership later for funding, but never one that distorts the editorial grading.
- How often is content updated?
- Every protocol carries a Last Reviewed date. Pages are reviewed at least annually, sooner when the MHRA, NHS, or NICE update relevant guidance, or when a major new study or systematic review materially changes the position on a topic.
- I noticed an error. How do I tell you?
- Email [email protected]. We aim to respond within five working days. Material errors get a dated correction note on the page; minor errors are fixed silently. See our corrections policy.
- I had a bad reaction to a supplement I read about. What do I do?
- Speak to a clinician first — NHS 111 for non-emergencies, 999 in an emergency. Then report the suspected adverse reaction to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. Anyone in the UK can submit a report.
- Why do you talk about UK regulators specifically?
- Because the regulatory landscape differs by country, and we are a UK educational publisher. The MHRA, FSA, ASA, NHS, and NICE are the bodies most relevant for our readers. Readers outside the UK can use much of the same biology but should check their own regulator's position on specific compounds.
- Is there a newsletter?
- Yes — one short email a month with newly reviewed protocols, any regulator updates from the MHRA, FSA, or NHS that touched topics we cover, and notable studies we read. Double opt-in. Unsubscribe link in every email.
- Can I create an account? Why would I?
- Yes. Sign up if you want to bookmark protocols and keep a private reading list. There are no public profiles, comments, or forum — just bookmarks. We don't share account information with third parties.
- Who writes this?
- The Biohacking Bible editorial team. Pages are reviewed before publication for adherence to our editorial policy, evidence-grading methodology, and ASA-safe language rules. We are not clinicians; the team includes editors with science-communication backgrounds.
- Why don't you cover peptides / SARMs / [specific compound]?
- Either because it's a prescription-only medicine in the UK (in which case dosing and sourcing guidance is outside our scope), because the published human evidence is too thin for an honest summary, or because the compound's regulatory status is unsettled and the harm potential is high. The site we want to read is the site that says "we don't have a good answer here" when the literature doesn't have one.
