On this page
What this community is for
Side-effect experience and management, with a strong bias toward the ones that are common and boring (nausea, constipation, reflux, fatigue, sulphur burps) and a hard line on the ones that are not (severe abdominal pain, persistent vomiting, jaundice, vision changes). This community is not a substitute for urgent care and the mods will say so bluntly.
c/sideeffects was created on 22 Aug 2023 and currently has 118,600 members and 130 captured submissions. It sits in the busiest tier of the site, which mostly affects how fast a question gets answered rather than how well.
The one-line version
GI, fatigue, hair, heart rate. What passes, what needs a doctor.
Rules, and why each exists
Community rules come first, then the six site-wide rules that apply everywhere on GLP Research Hub. Community rules are enforced by the moderators listed at the bottom of this page; site rules are enforced by everyone.
- Severe or escalating abdominal pain is an urgent-care question, not a forum question. We will lock those threads with a pointer to help.
- Describe your dose, your week number and your titration speed — otherwise nobody can help.
- No diagnosing strangers. Share what happened to you.
And the site rules, which are short on purpose:
- Independent community. Nobody here sells anything, and anyone who tries is banned.
- Not medical advice. Describe what you did; never prescribe to a stranger.
- Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
- No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
- No contact handles, wallet addresses or tracking numbers — they identify people.
- Be recognisably decent. Disagree hard, insult nobody.

If your question is on that list, read the answers there first. If it is not, ask it — that is what the community is for, and "this has been asked" is only a helpful reply when it comes with a link.
Who runs this
Moderation here is done by volunteers who also post as normal members. They are not clinicians, not vendors, and not paid.
- u/nausea_notes — Nausea log, 14 months, what helped and what was placebo. Ginger did nothing for me.
- u/constipation_club — Magnesium, fibre timing, hydration, movement. In that order of impact for me.
- u/quiet_moderator — I remove the obvious stuff so you never see it. Message the modmail, not me.
- u/gentle_correction — You can be right without being unkind. Usually.
