Compound Profiles

Finasteride

5-Alpha Reductase Inhibitor | DHT Blocker for Hair Loss & BPH

Finasteride competitively and selectively inhibits the Type II isoform of the enzyme 5-alpha reductase, which is predominantly found in hair follicles, the prostate, and the liver. This enzyme converts testosterone into dihydrotestosterone (DHT).

PP405

MPC Inhibitor | Hair Follicle Stem Cell Activation

PP405 is a dual inhibitor of the mitochondrial pyruvate carrier complex, targeting both the MPC1 and MPC2 subunits. Under normal conditions, the MPC transports pyruvate from the cytoplasm into the mitochondrial matrix, where it enters the tricarboxylic acid (TCA) cycle for oxidative metabolism.

Frequently Asked Questions

Can I take Finasteride with PP405?

Yes, Finasteride and PP405 can generally be taken together. Completely different mechanisms of action. Finasteride blocks DHT production via 5-alpha reductase inhibition, while PP405 targets hair follicle stem cell metabolism via MPC inhibition. Combination could be synergistic by addressing both hormonal miniaturization and stem cell dormancy simultaneously.

Is Finasteride and PP405 safe together?

Based on documented research, this combination is considered compatible. No critical safety flags identified for this pair.

What are the interactions between Finasteride and PP405?

Completely different mechanisms of action. Finasteride blocks DHT production via 5-alpha reductase inhibition, while PP405 targets hair follicle stem cell metabolism via MPC inhibition. Combination could be synergistic by addressing both hormonal miniaturization and stem cell dormancy simultaneously. This assessment has 90% confidence and is based on documented research data.

How should I time Finasteride and PP405?

Finasteride has a half-life of 6-8 hours (DHT suppression persists ~24 hours) and PP405 has a half-life of Topical application; exact pharmacokinetics not published. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.

This interaction analysis is compiled from research literature and pharmacological mechanism data. Always consult a healthcare professional before combining compounds.

Research context

Read sources and limitations before applying a claim.

Research Indications

Protects liver tissue through normalizing immune and antioxidant status. Restores liver functions in both acute and chronic hepatitis models. Shows protective properties in liver fibroid induration models. Decondenses chromatin to restore youthful gene expression patterns. Maximum hepatoprotective effects occur during aging. Activates silent genes including ribosomal genes for improved protein synthesis. Normalizes immune function alongside liver protective effects.

Community Research

Join others researching NA-Selank Amidate — share findings, ask questions, and learn from real experiences NA-Selank Amidate is an enhanced version of Selank, the anxiolytic nootropic peptide developed at Russia's Institute of Molecular Genetics. The N-acetyl group improves blood-brain barrier penetration and creates more stable metabolites, while the C-terminal amidation further enhances metabolic stability and receptor binding. Unlike benzodiazepines, it provides anxiety relief without sedation, dependency, or cognitive impairment. NA-Selank Amidate modulates multiple neurotransmitter systems including GABA, dopamine, and serotonin, while regulating brain-derived neurotrophic factor (BDNF). It allosterically modulates GABAA receptors without causing the sedation or dependency of benzodiazepines. The peptide activates serotonin metabolism in the hypothalamus and brainstem, and increases BDNF levels to promote neuronal growth and differentiation.
