ACP-105 is a compact non-steroidal compound (CAS 899821-23-9, molecular mass around 290.8 g/mol) that emerged from selective androgen receptor modulator programmes. It is neither a peptide nor a steroid: a small synthetic organic molecule with a bicyclic amine core, it engages the androgen receptor without the four-ring steroid skeleton found in testosterone and its derivatives.
What shapes its laboratory use is partial agonism. Even at saturating concentrations a partial agonist drives only a submaximal transactivation signal, and when a full agonist is present it can act as an antagonist — which makes such compounds better suited to studying receptor conformation and coregulator recruitment than to chasing the biggest response. The literature covers androgen receptor binding and transactivation assays, comparisons of tissue selectivity between muscle, bone and prostate, and rodent studies of cognition and behaviour. Limited solubility is the key practical issue: prepare stocks in DMSO or ethanol, dilute into medium, and keep the vehicle concentration identical in every well. A 30 mL solution at 20 mg/mL is offered for workflows where volumetric dilution beats repeated weighing of powder.

Questions about ACP-105
Does ACP-105 have a peptide structure?
No. It is a small non-steroidal organic compound of about 291 g/mol with no amino acid backbone at all. It sits in the selective androgen receptor modulator class, which has no chemical relationship to the peptides we sell, even if buyers often browse the two side by side.
What distinguishes it from RAD-140 or LGD-4033?
All three bind the androgen receptor without a steroid skeleton, yet their chemistry and published pharmacology diverge. ACP-105 is considerably smaller and is reported as a partial agonist, while RAD-140 and LGD-4033 usually behave as stronger full or near-full agonists in the assays described.
What documentation confirms purity?
Every lot is HPLC-tested to a minimum of 98% and comes with a certificate of analysis for that lot, including identity confirmation. Give us the lot number on your bottle when you request it. For a compound class sold widely outside regulated channels, verifying material yourself before assays is sensible.
May ACP-105 be purchased legally?
We supply it strictly as a research chemical for laboratory work. It is not an authorised medicinal product and may not be sold as a food or supplement ingredient in the EU. Each buyer must make sure their purchase and use comply with the rules of their own jurisdiction.
