Safety DocumentationStandard SDS available for YK-11
Terms of ApplicationFor laboratory research purposes only. Not for human or veterinary use. Investigated for its dual role as a partial agonist of the androgen receptor and its ability to induce follistatin expression, subsequently inhibiting myostatin in in-vitro cellular models (e.g., C2C12 myoblasts).

Foundational Scientific Overview

Foundational Scientific Overview

Injectable YK11 is a prominent and highly unique subject within the field of musculoskeletal research. Unlike traditional non-steroidal SARMs, YK11 possesses a steroidal backbone structurally similar to dihydrotestosterone (DHT), serving researchers examining partial androgen receptor agonism coupled with profound myostatin inhibition.

At 4-Amino-Labs, we provide this specialized compound in a highly purified format to ensure experimental reproducibility. By maintaining rigorous measurement standards, we provide the consistency required for longitudinal data integrity.

The biochemical pathway of YK11 acting not just as an androgen receptor agonist, but fundamentally driving anabolism through the induced expression of follistatin (a primary myostatin inhibitor), is highly documented. See: Kanno, Y., et al. (2011). "Selective androgen receptor modulator, YK11, regulates myogenic differentiation of C2C12 myoblasts by follistatin expression." Biological and Pharmaceutical Bulletin, 34(3), 318-323.

FormulaC25H34O6
Physical StateFine White Crystalline Solid (raw material)
Supplied Formats15mg/mL MCT oil (10mL), 30mg/mL MCT oil (20mL), 10mg/mL PEG-400 solution (30mL), 50-count tablets

Investigational Pathways

Follistatin Expression
Evaluating the compound’s unique capacity to induce the secretion of follistatin from myoblast cultures, effectively neutralizing myostatin.
Partial AR Agonism
Observing the downstream transcriptional activation at the androgen receptor, which initiates the myogenic differentiation cascade.
Bone Morphogenetic Protein (BMP) Crosstalk
Mapping the flux of osteoblastic activity and bone mineralization driven by follistatin interactions.

Laboratory Handling and Stability

Thermal Regulation
Store in a strictly controlled, desiccated environment at room temperature.
Photostability
Protect from direct UV exposure; storage in an opaque container or dark cabinet is advised to prevent photodegradation.
Contamination Control
Use sterilized instruments and work within a laminar-flow hood, when possible, to maintain sample sterility.
