Evaluation of Glucuronide Metabolite Stability in Dried Blood Spots

Pyrilutamide's long-term stability is uncertain, with potential degradation after 8-9 months if not stored properly. It's recommended to use fresh batches and store them in a cool, dark place.

RU58841 solution may lose efficacy after 12 months, and the stability of pre-mixed solutions is uncertain. The user is considering switching suppliers due to concerns about product quality.

The conversation discusses concerns about RU58841 degrading when exposed to light and transferring pyri to a dark glass bottle to prevent this. The user keeps the pyri out for only two minutes before storing it in a dark place.

RU58841 powder may degrade over time, even when stored in a freezer. Users discuss its potential effectiveness after three years of storage.

RU58841 can be absorbed systemically after topical application, but the study did not find immediate hormonal disruption. The study highlights the need for more research on long-term safety and effects of RU58841, as well as the importance of quality control in products from the grey market.

Pyrilutamide's systemic degradation is unclear, unlike fluridil, which becomes inactive in the body. The discussion focuses on whether pyrilutamide shares this property.
