c/labresults wiki

What this community is for

A running record of independent test results people paid for themselves. Every post follows the same shape: vendor, product, batch, testing service, method, and the number. Good results and bad results are equally welcome and get equal scrutiny.

c/labresults was created on 2 Oct 2023 and currently has 44,200 members and 95 captured submissions. It sits in the second tier of the site, which mostly affects how fast a question gets answered rather than how well.

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.

1. Template required: vendor / product / batch / service / method / result. Freeform posts get removed with a template reply.
2. Do not editorialise in the title. Put the number in the title and the opinion in the body.
3. Sample of one. Say so.

And the site rules, which are short on purpose:

1. Independent community. Nobody here sells anything, and anyone who tries is banned.
2. Not medical advice. Describe what you did; never prescribe to a stranger.
3. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
4. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
5. No contact handles, wallet addresses or tracking numbers — they identify people.
6. Be recognisably decent. Disagree hard, insult nobody.

Terms you will see

Vocabulary that turns up constantly in c/labresults. Each links to the topic page, which collects every submission that touches it.

• test results — discussed frequently in this community — see the topic page for every submission that touches it.
• Janoshik — independent testing service, the most-used by members here.
• Medutest — independent testing service, often used as a second opinion.
• PeptideMeter — independent testing plus published vendor-level trend data.
• purity — usually area% from a UV chromatogram: how much of what the detector saw was product.
• batch — a single production run; the unit a COA actually describes.
• below spec — discussed frequently in this community — see the topic page for every submission that touches it.

Asked constantly

• [Question] how do you actually verify batch
• [Question] how do you actually verify Janoshik
• [Question] below spec — what am I missing here

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/janoshik_junkie — I pay for third-party tests so you do not have to. Results posted regardless of outcome.
• u/medutest_mel — Sends duplicates to two services and compares. Usually they agree. Usually.
• u/peptidemeter_pat — Tracks vendor-level averages over time. The trend is the signal.
• u/coa_janitor — c/coa mod. If your COA screenshot is cropped above the batch number I will ask you to repost it.
