A tour of Ask PeptideStack

Ask PeptideStack is a question-and-answer site, not a forum. The difference is not cosmetic, and it is worth two minutes of your time because it changes how you should use the place.

One question per page

A forum thread is a conversation with a topic. A question here is a single interrogative with a single canonical URL, and everything on that page exists to answer it. There is no "bump", no "following", no page seven. If your question is different from an existing one, it gets its own page; if it is the same, it gets closed as a duplicate and points at the original.

Answers are ranked, and one can be accepted

Answers are sorted by community vote, except that an accepted answer sorts first regardless of its score. The green check means the person who asked found it resolved their problem — which is useful information and is not the same as "correct". Occasionally the accepted answer is not the highest-voted one, and when that happens it is usually worth reading both and working out why.

Comments are a third thing: one-liners for corrections, requests for clarification and pointers. A comment is not an answer, and posting an answer as a comment is the most common newcomer mistake on any site of this kind.

Reputation is the only credential we can verify

Nobody here is credentialled by us. What we can observe is whether someone has repeatedly said things that other people, reading in public, found correct — and reputation is a compressed record of that. Ten points per upvote on an answer, fifteen for an acceptance, five for an upvoted question. It is a proxy, it is gameable in principle, and it is still the most informative thing on an author card.

The five highest-reputation contributors at present:

Tags, not boards

There is no board hierarchy. A question carries between two and five tags, so a question about whether a warm-arrived vial is worth testing sits simultaneously under cold-chain, batch-testing and harm-reduction. That is deliberate: the analytical questions and the sourcing questions are the same questions viewed from different angles, and a tree structure would hide that. There are 107 tags and each has a landing page with a description and its related tags.

The one norm that matters

Answers carry sources. A clinical claim is expected to cite a published trial by name, journal and year. A supplier claim is expected to cite an independent batch test. "It worked for me" is data about one person and is welcome as such, clearly labelled, and it does not settle an analytical question.

The corollary is that "I do not know" is an acceptable and frequently upvoted answer here, provided it explains what would be needed to find out.

What this site is not

• Not a shop. We sell nothing. Each vendor profile links that vendor's own storefront, marked nofollow and sponsored, and the other outbound links on the site are clearly labelled sponsor units.
• Not a clinical service. Nothing here is medical advice. Several of the most-upvoted answers on the site say, in effect, "this is a question for a clinician, and here is why".
• Not neutral about evidence. We are explicitly partisan in favour of measurement over assertion, and the tone reflects that.
• Not live. This is a static archive. Vote buttons are rendered because the scores are real records; clicking them does nothing.

Where to start

• The reconstitution calculator, if you came here with arithmetic.
• How to read a certificate of analysis, if you came here with a document.
• The highest-voted questions, if you came here to browse.
• Unanswered questions, if you came here to contribute.
• The sourcing policy, if you intend to make a claim about a supplier.
