What is 5CL‑ADB‑A MDMB‑4en‑PINACA (also incorrectly known as 5‑CL‑ADB‑A)?
MDMB‑4en‑PINACA is an indazole‑based synthetic cannabinoid that acts as a potent agonist at the CB1 receptor, structurally related to 5F‑MDMB‑PINACA and other designer cannabinoids that have appeared in forensic casework since around 2017. MDMB‑4en‑PINACA has often been mislabelled as 5CL‑ADB‑A, which has contributed to confusion in seized sample reports, legal control lists, and even some vendor catalogues.[1][2]
At Davechemicals.com official website we treat 5CL‑ADB‑A MDMB‑4en‑PINACA as a technical research material, with a clear warning that all products are for research purposes only and not for human consumption.
Why buy 5CL‑ADB‑A MDMB‑4en‑PINACA online for research from Davechemicals.com? 💻
Researchers looking to buy 5CL‑ADB‑A online are usually trying to work around messy street samples and inconsistent purity. Our focus is simple: clean documentation, predictable quality, and straightforward ordering for qualified labs.[2]
We have built a catalogue that includes related synthetic cannabinoids such as buy 5CL‑ADB‑A online, buy ADB‑FUBINACA online, buy 5F‑UR144 online and JWH‑210 cannabinoid so that labs can compare older and newer compounds side by side in a controlled environment.[1][2]
Our position is blunt: if you are not a serious lab, you should not be touching 5CL‑ADB‑A MDMB‑4en‑PINACA at all.
Chemical profile of MDMB‑4en‑PINACA and the “5CL‑ADB‑A” confusion
According to reference data from sources such as DrugBank and Wikipedia on MDMB‑4en‑PINACA, this compound is:
- An indazole‑3‑carboxamide with a methyl 3,3‑dimethylbutanoate side chain and a terminal alkene in the N‑alkyl tail.[2][1]
- A strong CB1 receptor agonist with reported in‑vitro EC50 in the low nanomolar range, several times higher potency than early compounds like JWH‑018.[1][2]
Misuse of the name 5CL‑ADB‑A has appeared in seizure reports and online catalogues, although MDMB‑4en‑PINACA does not contain a chlorine atom. That mix‑up matters to forensic chemists attempting to identify unknowns or interpret quantitative results in casework.[2][1]
For context, other modern synthetic cannabinoids, such as 4F‑ADB, AM‑2201, SGT‑25 and buy SGT‑151 online are often studied alongside MDMB‑4en‑PINACA to understand structure‑activity relationships and analytical cross‑reactivity.[1][2]
How 5CL‑ADB‑A MDMB‑4en‑PINACA is used in labs (not in people)
Serious labs and forensic teams use compounds like MDMB‑4en‑PINACA as reference standards to:
- Validate LC‑MS or GC‑MS methods for seized herbal blends and e‑liquids, often guided by documents from agencies and reports hosted by organisations such as the EMCDDA.[2]
- Compare analytical profiles with other synthetic cannabinoids documented on resources such as PsychonautWiki and TripSitter, particularly when local casework turns up unfamiliar peaks.[2]
Our own catalogue also supports broader NPS investigations, for example with buy 5F‑MDMB‑2201 online, buy 5F‑SGT‑151 online, buy AMB‑PINACA online and EG‑018 for comparison studies.[1][2]
Key point: Our 5CL‑ADB‑A MDMB‑4en‑PINACA is supplied to help scientists untangle the mess created by uncontrolled street products, not to feed that market.
Legal and safety reality of MDMB‑4en‑PINACA and similar cannabinoids
Reports collected by agencies and summarised in technical reviews describe serious toxicity, including acute intoxication, cardiovascular stress and deaths linked to MDMB‑4en‑PINACA products in several countries. According to one EMCDDA rapid assessment, MDMB‑4en‑PINACA has been one of the most frequently detected synthetic cannabinoids in some seizure datasets, often in herbal smoking mixtures with unknown strength.[2]
Resources such as Drugs.com and DrugBank both highlight the unpredictable nature of many new psychoactive substances, especially when potency exceeds that of natural cannabis by an order of magnitude or more. That is precisely why our products, including buy ADB‑BUTINACA, buy 6CL‑ADB‑A online and buy AD‑18 online, are framed strictly as research‑only materials with explicit not for human consumption messaging.[3][4]

How 5CL‑ADB‑A MDMB‑4en‑PINACA compares with other synthetic cannabinoids
According to open access reviews and technical summaries, MDMB‑4en‑PINACA tends to display stronger CB1 efficacy and higher receptor affinity than older compounds such as JWH‑018, which is one reason why intoxication cases can be so severe. Community‑level harm reports collected by projects referenced on TripSitter and PsychonautWiki echo those concerns, with clusters of emergency presentations linked to small doses of synthetic cannabinoid products.[1][2]
This is why many toxicology labs now work with panels of standards, such as 5F‑UR144, JWH‑122, JWH‑201 and JWH‑250 for sale alongside MDMB‑4en‑PINACA, to keep their libraries up to date.
FAQs: What is 5CL‑ADB‑A MDMB‑4en‑PINACA and how is it used?
Below are questions that repeatedly appear on search platforms and AI engines about MDMB‑4en‑PINACA and its mislabel 5CL‑ADB‑A, adapted into clear responses.
1. What is 5CL‑ADB‑A MDMB‑4en‑PINACA?
5CL‑ADB‑A MDMB‑4en‑PINACA is a label often used in the market for the compound MDMB‑4en‑PINACA, an indazole‑based synthetic cannabinoid that acts as a strong CB1 receptor agonist, structurally related to other designer cannabinoids used in herbal smoking mixtures. It has appeared in forensic casework worldwide and is treated as a high‑risk new psychoactive substance by agencies and toxicologists.[1][2]
2. Why is MDMB‑4en‑PINACA sometimes incorrectly called 5CL‑ADB‑A?
The “5CL‑ADB‑A” name seems to stem from early mislabelling and vendor catalogues, even though the molecule as characterised in analytical reports does not contain a chlorine atom. That incorrect name stuck in parts of the market, which is why technical documents now often highlight that MDMB‑4en‑PINACA is also incorrectly known as 5CL‑ADB‑A to prevent further confusion.[1][2]
3. Is 5CL‑ADB‑A MDMB‑4en‑PINACA legal in the UK, USA, Germany and Australia?
Legal status changes quickly, but MDMB‑4en‑PINACA has already been placed under control in several jurisdictions, for example, temporary Schedule I in the United States from 2023, with similar controls in parts of Europe and other regions. Anyone considering working with 5CL‑ADB‑A MDMB‑4en‑PINACA must check current national and regional legislation, internal institutional policies and import rules before ordering.[2][1]
4. What is 5CL‑ADB‑A MDMB‑4en‑PINACA used for in research?
Legitimate uses include: building LC‑MS and GC‑MS libraries, calibrating quantitative assays, confirming identity in seized casework and exploring metabolism in controlled in‑vitro systems. According to technical reviews, these kinds of studies help toxicologists interpret blood or urine results when emergency departments report unusual clinical pictures.[2]
5. How does 5CL‑ADB‑A MDMB‑4en‑PINACA compare in risk to natural cannabis?
Open source data and technical summaries describe synthetic cannabinoids like MDMB‑4en‑PINACA as substantially more potent at the CB1 receptor than Δ9‑THC. According to one European risk assessment, associated harms include severe agitation, unconsciousness, seizures and deaths, which sit far outside the typical profile of natural cannabis and support strict not for human consumption handling.[2]
6. Can general consumers safely use 5CL‑ADB‑A MDMB‑4en‑PINACA?
There is no safe consumer use scenario here. The compound is a lab tool, has been linked with serious toxicity, and is controlled or proposed for control in many countries. At Davechemicals.com we will not pretend otherwise, which is why every listing, including buy 5CL‑ADB‑A online, clearly states “for research purposes only, not for human consumption”.[1][2]
7. Which other research chemicals pair with 5CL‑ADB‑A MDMB‑4en‑PINACA for broader projects?
Labs often order panels that span multiple classes, for example buy eutylone online and buy methylone online for stimulant work, buy 3‑MeO‑PCP online and buy 2‑BDCK online for dissociatives, and buy tianeptine online or fentanyl powder for sale for opioid‑related panels, alongside synthetic cannabinoids like MDMB‑4en‑PINACA. That kind of spread reflects real‑world casework, where mixtures of different NPS often show up together.[2]
