1) What are SARMs?

SARMs (Selective Androgen Receptor Modulators) are a class of synthetic compounds designed to interact with the androgen receptor (AR), with the original drug-development goal of creating more selective androgen-receptor activity than traditional anabolic-androgenic steroids.

2) How SARMs work (mechanism overview)

At a high level, SARMs are designed to:

  • Bind the androgen receptor (AR) and influence androgen-signaling pathways

  • Aim for functional selectivity across tissues (a design goal often discussed in the literature and product marketing)

3) SARMs vs anabolic steroids (high-level comparison)

Both SARMs and anabolic-androgenic steroids (AAS) relate to androgen signaling, but they differ in how they were engineered and how they are commonly categorized:

  • AAS: steroidal structures, long-established history of medical and non-medical use

  • SARMs: non-steroidal structures (in most cases), designed to modulate AR signaling with a “selective” intent

4) Commonly discussed SARMs (research context)

These are some of the most frequently referenced SARMs in online research discussions and market listings:

5) Commonly bundled “SARM-adjacent” compounds (not SARMs)

A lot of “SARMs” catalogs include compounds that are not SARMs, but are frequently discussed alongside them. The three most common are:

MK-677 (Ibutamoren) — not a SARM

  • Often grouped with SARMs in product catalogs, but it is typically described as a growth hormone secretagogue in scientific discussion (not an androgen receptor modulator).

GW-501516 (Cardarine) — not a SARM

  • Commonly described as a PPARδ agonist, frequently sold in the same ecosystem as SARMs, but it is not a selective androgen receptor modulator.

SR9009 — not a SARM

  • Often described as a Rev-erb agonist in research discussions; frequently marketed next to SARMs despite being a separate category.

6) Documentation in research supply chains (COA basics)

In legitimate chemical and research supply chains, it’s common to see documentation such as:

  • Certificate of Analysis (COA) (e.g., identity/purity summaries, method references)

This guide does not evaluate any supplier and does not provide procurement guidance; it’s simply an overview of documentation types commonly referenced in research contexts.

7) FAQ (Canada, 2026)

What are SARMs in simple terms?

SARMs (Selective Androgen Receptor Modulators) are compounds studied for how they interact with the androgen receptor (AR). In research discussions, they’re often used as a lens to explore androgen signaling, receptor binding, and downstream biological pathways.

What does “selective” mean with SARMs?

“Selective” usually refers to the idea that different compounds may produce different patterns of receptor activity depending on tissue context, signaling pathways, and molecular structure. In research terms, it’s about how a compound modulates receptor activity.

Which SARMs are most commonly referenced in research discussions?

In the broader research and enthusiast ecosystem, the most commonly referenced SARMs include:

  • MK-2866 (Ostarine / Enobosarm)

  • LGD-4033 (Ligandrol)

  • RAD-140 (Testolone)
    These show up frequently because they’re widely discussed as “core” AR modulators in many SARMs overviews.

Are MK-677, GW-501516 (Cardarine), and SR9009 SARMs?

No—these are not SARMs, but they’re often discussed in the same circles:

  • MK-677 (Ibutamoren) is generally described as a growth hormone secretagogue.

  • GW-501516 (Cardarine) is generally described as a PPARδ agonist.

  • SR9009 is often described as a Rev-erb agonist.
    They get grouped together mainly because they’re marketed as part of a broader “research compounds” category.

Why do people group SARMs with MK-677 / Cardarine / SR9009?

Because many people search “SARMs” as shorthand for the entire research-compound ecosystem. A helpful mental model is:

  • SARMs → primarily AR-focused discussion

  • MK-677 / GW-501516 / SR9009 → different targets, often discussed alongside SARMs for category overlap in catalogs and forums

What’s the best way to compare products across compounds?

For a clean apples-to-apples comparison in a research context, focus on:

  • Total amount (e.g., total mg per bottle/vial)

  • Concentration (e.g., mg/mL for solutions)

  • COA availability (what’s documented and which method is referenced)
