Searches for LGD 4033 keep climbing, and most come down to two questions: what is this compound, and where can it be sourced safely? This guide answers both. It covers Ligandrol's identity, formats, specifications, purity standards and UK sourcing, written entirely as research reference.

Here is the short version. LGD-4033 and Ligandrol are the same research compound, and it is a nonsteroidal selective androgen receptor modulator (SARM). It is sold in the UK for research purposes only, and the single thing that matters most when buying is verified purity backed by independent testing.

What Is LGD-4033 (Ligandrol)?

LGD-4033, also called Ligandrol, is a research compound classified in the scientific literature as a nonsteroidal selective androgen receptor modulator (SARM). It was first described in published research in the 2010s. In the UK it is supplied strictly for laboratory research purposes only, not for human or animal consumption.

The "LGD-4033" label is a development code. "Ligandrol" is the common research name. Both point to the same molecule, which is why a search for "lgd 4033", "lgd-4033" or "ligandrol" returns the same compound.

LGD-4033 and Ligandrol: the Same Compound, Different Names

There is no difference between LGD-4033 and Ligandrol. One is the development code, the other is the research name in common use. Research papers and product listings use the terms interchangeably.

Names and Codes You Will See

This compound appears under several spellings, and knowing them helps when searching the literature or checking documentation:

• LGD-4033 and LGD4033: the development code, with or without the hyphen.
• lgd 4033: the spaced form frequently used in searches.
• Ligandrol: the common research name.
• VK5211: an alternative development code seen in some records.
• Anabolicum: a nickname the compound appears under in some listings.

When sourcing LGD-4033 liquid in the UK, the name on the Certificate of Analysis should match one of these recognised forms. That is a small but useful check on documentation accuracy.

How LGD-4033 Is Classified in the Literature

In scientific reference databases, Ligandrol is classified as a nonsteroidal selective androgen receptor modulator. This is a chemical classification only. It identifies the compound's category, in the same way a label like "solvent" identifies a class, and is included here purely for accurate identification of the research material.

Is LGD-4033 a SARM?

Yes. LGD-4033 is a SARM. Unlike some research compounds that are frequently grouped with SARMs by mistake, Ligandrol genuinely belongs to the selective androgen receptor modulator category in the scientific literature, and it is one of the most referenced compounds in that class.

Why LGD-4033 Is Classified as a SARM

SARMs are a class of nonsteroidal research compounds catalogued together by their chemical mode of classification. LGD-4033 (Ligandrol) sits in this class alongside compounds such as RAD140 and Ostarine (MK-2866). For any research reference library, grouping these correctly keeps the catalogue accurate.

How LGD-4033 Differs from MK677 and Peptides

This is where confusion is most common. MK677 (Ibutamoren) is often listed next to SARMs but is not a SARM: it is catalogued separately as a non-peptide ghrelin receptor agonist. Peptide-based research materials such as BPC-157 sit in another category again. LGD-4033 is distinct from both: a nonsteroidal SARM. The distinction matters for classification, handling, and storage rather than for any functional claim.

LGD-4033 Liquid and Capsule Formats Explained

LGD-4033 is offered in two main research formats in the UK: liquid and capsules. The difference is one of handling and measurement in a research setting. Nxt Level Labz supplies it in liquid format.

How Liquid and Capsule Research Formats Differ

Liquid form is already in solution, which lets researchers measure precise volumes for repeatable laboratory protocols. Capsules contain a pre-set fixed amount per unit. For controlled research handling, the measurement flexibility of liquid is the main practical reason it is preferred by laboratories.

LGD-4033 Liquid Concentration and Volume

It is described by its concentration and bottle volume, for example, 10mg/ml in a 30ml bottle. The concentration states how much compound is present per millilitre of solution and is listed on the product page. Separately, the Certificate of Analysis confirms the purity and identity of the compound — for example, 99%+ purity verified by HPLC — rather than the concentration.

You can view the current concentration, volume, and COA on the LGD-4033 liquid product page.

LGD-4033 Specifications and Chemical Reference Data

The table below sets out standard reference data for Ligandrol. Always confirm the exact values against the authoritative record on PubChem.

For the full published record, the standard index is the PubMed LGD-4033 listing. Working from primary sources is what separates accurate reference material from thin product copy.

How to Buy LGD-4033 in the UK Safely

For anyone searching to buy LGD-4033 in the UK, the decision should rest on verifiable standards, not marketing language. The points below are what actually matter.

What to Look For in a UK LGD-4033 Supplier

A trustworthy UK supplier meets a clear set of standards:

• Verified purity: 99%+, independently third-party tested.
• An accessible Certificate of Analysis: viewable, not just referenced.
• Liquid format: for precise volume measurement in protocols.
• UK-based dispatch: same-day where possible, with tracked delivery.
• Research-only positioning: no human-use language anywhere on the site.

Third-Party Testing and Certificates of Analysis (COA)

A Certificate of Analysis records a compound's purity and identity. The benchmark for research-grade material is 99%+ purity, verified by HPLC, by an independent third-party laboratory. A manufacturer's own certificate alone is a weaker standard than independent re-testing. All compounds stocked by Nxt Level Labz are independently third-party tested, with a COA available on the third-party testing page.

Same-Day Dispatch and Tracked UK Delivery

Dispatch speed matters on research timelines. Nxt Level Labz dispatches orders placed before 4PM the same working day, using tracked UK delivery. That lets a shipment be followed from dispatch through to arrival.

How Much Does LGD-4033 Cost in the UK?

LGD-4033 prices in the UK vary by format, concentration, and supplier standards. Independent third-party testing adds cost but adds confidence, and the lowest price often signals a corner cut on testing or quality control. A product with no accessible COA or vague purity claims is a saving that is not worth making. The current price and stock are shown on the LGD-4033 liquid page.

How to Store LGD-4033 Liquid

Correct storage protects the integrity of the compound between receipt and use in the laboratory.

Storage and Handling for Research Integrity

Store it in a cool, dry place away from direct sunlight, and keep it out of reach of children. Handle it in line with good laboratory practice. Refrigeration is recommended for longer-term storage to help maintain stability over time.
