4First-aid measures

First Aid Measures

Inhalation: Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor.
Skin: Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice.
Eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell.
General: If exposed or concerned, get medical advice. Show this safety data sheet to the doctor. Pregnant or nursing laboratory staff should avoid exposure.

Most Important Symptoms And Effects

No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption.

Likely Routes Of Exposure

Ingestion; inhalation of dust and skin/eye contact if capsules are opened.

5Fire-fighting measures

Fire Fighting Information: Combustible organic solid; capsule contents may form combustible dust if dispersed in bulk.

6Accidental release measures

Spill And Clean Up Procedures: Collect intact capsules. Dampen any spilled powder with water, wipe up with absorbent material and place in a sealed container for disposal.

7Handling and storage

Safe Handling: Do not open or crush capsules unless required for an experiment; if capsule contents are handled as a powder, avoid generating dust and weigh inside a ventilated enclosure. Wash hands after handling.
Safe Storage: Store at room temperature (15–25 °C) in the tightly closed original container, dry and protected from light.
Storage Temperature: 15–25 °C, dry, protected from light
Incompatible Materials: Oxidizing agents (Cayman)

8Exposure controls / personal protection

Occupational Exposure Limits: Microcrystalline cellulose: OSHA PEL 15 mg/m³ (total dust), 5 mg/m³ (respirable fraction); ACGIH TLV 10 mg/m³ (as cellulose).

No occupational exposure limits have been established for the active ingredient(s).
Exposure Controls And PPE: No data available.

14Transport information

Transport Classification

Note: Not regulated as a dangerous good for transport by road (DOT 49 CFR), air (IATA/ICAO) or sea (IMDG). Not a marine pollutant. Ship refrigerated or frozen as required by Section 7; the coolant (dry ice, UN 1845) is regulated when used.

15Regulatory information

Regulatory Information

Dea: Not a federally controlled substance (SARMs are not scheduled; SARMs Control Act proposals pending)
Other: WADA Prohibited List S1.2 'Other anabolic agents' (SARMs) - prohibited at all times (remark only). FDA has issued warnings that SARMs are unapproved drugs and must not be marketed in dietary supplements.

Confidence: high
Additional Information: Selective androgen receptor modulator (SARM). No supplier SDS assigns a reproductive classification, but SARMs act on the androgen receptor, suppress gonadotropins and spermatogenesis in animal and human studies and are prohibited at all times under WADA class S1.2. PrymaLab therefore self-classifies the substance as Reproductive toxicity Category 2 (H361) by expert judgement.
