The vendor status tracker is a section of Amino Axiom, a free research information platform, that records which research-compound vendors are no longer operating, the reason each one stopped, and the FDA enforcement timeline that surrounds those closures. It is available at the Amino Axiom vendor status tracker.
For a researcher doing supplier vetting, a status page answers a question that a catalog or a rating cannot: is this vendor still in business, and if not, what happened. That matters because sourcing records outlive suppliers. A lab may hold batches, certificates and purchase history from a vendor that has since closed, and the closure changes how those records should be read. This FAQ describes what the tracker displays and how a person in a sourcing role would use it. It does not go beyond what the page visibly shows.
What does the tracker list?
Three kinds of information appear on the tracker: status, reason and timeline. Each answers a different sourcing question, and a researcher reading an entry should take them in that order, since the status decides whether the other two matter for a given vendor.
Status answers whether a vendor is defunct. A vendor marked defunct is one that has ceased operating, as opposed to one that is merely quiet or has changed its storefront.
Reason answers why. Closures have different causes, and the cause affects how much weight a researcher should give to historical documentation from that vendor. A voluntary wind-down and an enforcement-driven shutdown are different situations, even though the practical result for a buyer is the same.
Timeline answers when. The tracker places closures against FDA enforcement activity in sequence, so a reader can see which closures cluster around which regulatory events. A timeline is context, not proof of causation, and the tracker is best read as an ordered record rather than an explanation.
Why does vendor status matter for supplier vetting?
Status matters because vetting is usually framed around operating vendors, and the tracker adds the other side of the ledger. A defunct vendor affects stale leads, existing records and continuity planning. Three practical points follow, and each is a reason to run a status check before spending time on any supplier lead.
First, it protects against stale information. Forum posts, old ratings and archived storefront pages continue to circulate after a vendor is gone. A researcher who finds a favorable mention of a supplier has no way to tell from the mention alone whether the supplier still exists. A status check is a quick filter that removes dead leads before any time is spent on them.
Second, it informs the reading of existing records. If a lab holds a certificate of analysis from a vendor that later closed, that certificate is still a document about a specific batch, but the vendor can no longer be asked to clarify it, reissue it or confirm it. The record has to stand on its own, which raises the importance of having kept the full documentation. Our guide to COA recordkeeping covers how to retain it in a form that survives a supplier disappearing.
Third, it supports continuity planning. A project that depends on one supplier for one compound has a single point of failure. Seeing how often vendors in the space close is a reasonable argument for qualifying a second source before it is needed.
How should the enforcement timeline be read?
The timeline places FDA enforcement events in order next to vendor closures. A careful reader should treat it as a sequence of dated entries and avoid inferring more than the dates show.
Two closures that fall in the same month may or may not be connected. A closure that follows an enforcement event may reflect that event, or may reflect an unrelated business decision made around the same time. The tracker presents the order of events. Drawing a causal line between any two of them is the reader's inference, and a sourcing record should say so if it records one.
For a researcher the useful read is pattern-level. If many closures cluster in a short window, the supplier landscape changed quickly in that window, and any sourcing decision made from information older than the window should be revisited. Our overview of FDA peptide enforcement in 2026 gives the regulatory background that the timeline sits against.
How does this connect to a specific compound?
A worked example keeps the process concrete. Take BPC-157, a 15-residue synthetic peptide that Onward Aminos lists with CAS 137525-51-0, molecular weight 1419.56 g/mol and formula C62H98N16O22. Suppose a researcher has an older purchase record for this compound from a vendor and wants to decide whether to rely on the paperwork.
Check the vendor's name against the tracker.
If the vendor is marked defunct, note the stated reason and the date.
Locate the retained batch documentation for the material in hand.
Compare the identifiers on that documentation with the reference values above: CAS, molecular weight and formula.
Record the outcome, including the vendor's status at the time of review.
The identifiers are the stable part of the check. A vendor can disappear, but the formula and molecular weight of the compound do not change, so a retained document can still be tested against them. If the numbers match, the document is at least internally consistent with the compound. If they do not, the closure removes the option of asking the vendor to explain, and the discrepancy has to be resolved some other way.
The same sequence applies to Selank, listed with CAS 129954-34-3, molecular weight 751.86 g/mol and formula C33H57N9O15, or to TB500. Only the reference values change.
What can a status tracker not tell a researcher?
The tracker has three limits, and each one marks where status information stops and batch verification starts. An entry is not a quality assessment, it is a point-in-time record, and it does not replace analytical evidence. A researcher should hold all three in mind when using it.
A status entry is not a quality assessment. A vendor that closed may have supplied excellent material, and a vendor that is still operating may not have. Status describes whether a business exists, not how good its batches were.
A status entry is a point-in-time record. A vendor shown as operating today may not be next quarter, so a status check supports a decision only at the moment it is made, and a long-running project should repeat it.
A status entry does not substitute for batch verification. Whether a given vial matches its stated identity and purity is determined by analytical evidence for that batch. Our explanation of HPLC purity testing covers what a chromatographic figure does and does not establish, and it remains the relevant reference regardless of whether the vendor is still around.
How can the tracker be folded into a sourcing checklist?
A short addition to an existing vetting checklist is enough. Before a vendor is considered, confirm its status. Before an old record is relied on, confirm the status of the vendor that issued it. When a vendor is found to be defunct, write down the date of the check and the reason shown, so the entry can be understood later without repeating the lookup.
It also helps to separate two uses. One is forward-looking, deciding whom to source from. The other is backward-looking, deciding how far to trust records already held. The tracker serves both, but the questions differ, and mixing them leads to muddled notes.
Amino Axiom describes itself as a research information and tracking platform, and the tracker should be used in that spirit: an organized record of status and timing, with verification still resting on batch documentation and the researcher's own files. The platform's homepage is at Amino Axiom for readers who want wider context on the site.
Summary
The vendor status tracker shows whether a vendor is defunct, the reason given and where the closure falls against FDA enforcement events. For supplier vetting it removes stale leads, changes how retained records should be read, and argues for qualifying more than one source. It does not assess quality and it is a snapshot in time. The dependable pattern is to check status, then verify the batch against published identifiers, then record both outcomes.

Common questions
It shows which research-compound vendors are defunct, the reason each one stopped, and the FDA enforcement timeline placed alongside those closures. It answers whether a vendor still operates and what happened if it does not. It does not rate batch quality or verify any material. For research purposes only.
A defunct status removes stale leads and changes how retained records are read. Old ratings and forum mentions persist after a vendor closes, and a closed vendor can no longer clarify, reissue or confirm a certificate of analysis. Retained documentation then has to stand on its own. For research purposes only.
No. The tracker presents dated entries in order, and sequence is not causation. A closure after an enforcement event may reflect that event or an unrelated business decision. Any causal link between two entries is the reader's inference, and a sourcing record should label it as such. For research purposes only.
It remains a document about a specific batch, and its identifiers can still be tested against catalog reference values for CAS number, molecular weight and formula. Those values do not change when a vendor closes. A mismatch cannot be resolved with the vendor, so it must be settled by other means. For research purposes only.
