Compound Profiles

Primobolan

Anabolic Steroid | Lean Mass & Low Side Effect Profile

Metenolone binds to the androgen receptor (AR) to promote nitrogen retention, protein synthesis, and anti-catabolic effects in skeletal muscle tissue. As a DHT derivative, it cannot be aromatized by the aromatase enzyme, meaning it produces no estrogenic metabolites and does not contribute to water retention, gynecomastia, or estrogen-mediated fat gain.

RAD-140

Selective Androgen Receptor Modulator | Investigational SARM

RAD-140 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a full agonist in muscle and bone tissue while exhibiting minimal agonist activity in the prostate and other androgen-sensitive tissues. This tissue selectivity is achieved through differential cofactor recruitment: upon binding to the AR, RAD-140 induces a conformational change that favors interaction with coactivators predominantly expressed in skeletal muscle and bone, rather than those prevalent in prostate or sebaceous glands.

Frequently Asked Questions

Can I take Primobolan with RAD-140?

Combining Primobolan with RAD-140 is not recommended. Both Primobolan and RAD-140 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.

Is Primobolan and RAD-140 safe together?

This combination carries significant risk. Both Primobolan and RAD-140 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. Consult a healthcare professional before combining.

What are the interactions between Primobolan and RAD-140?

Both Primobolan and RAD-140 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. This assessment has 53% confidence and is inferred from pharmacological mechanism analysis.

How should I time Primobolan and RAD-140?

Primobolan has a half-life of ~10 days (enanthate) and RAD-140 has a half-life of ~60 hours. 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. This assessment is inferred from known mechanisms and may not reflect all real-world outcomes. Always consult a healthcare professional before combining compounds.

Research Indications

VIP inhalation shows striking efficacy with increased mixed venous oxygen saturation and exercise capacity. Dilates peripheral blood vessels through NO-dependent mechanisms above 100 pmol doses. Coronary vasodilation with positive inotropic and chronotropic effects on the heart. Promising therapeutic target for Alzheimer's, Parkinson's, and other neurological disorders. Potential therapeutic target being researched for ASD. Produced in suprachiasmatic nuclei; involved in circadian regulation. Promotes insulin secretion in glucose-dependent manner via VPAC2; low hypoglycemia risk. Potent anti-inflammatory effects useful in IBD and autoimmune conditions. Therapeutic potential for pulmonary and systemic sarcoidosis.

Is PNC-27 closer to clinical trials than other peptide cancer therapies?

Not yet. PNC-27 remains in preclinical research with no human clinical trials initiated as of 2025. While it's been studied since 2000, it hasn't progressed to human testing. That's partly because cancer drug development is slow and partly because peptide therapeutics face delivery challenges that are being actively researched.

Dosing Protocols

PP405 is formulated as a 0.05% topical gel for once-daily application to the scalp. This is the only formulation currently under clinical investigation. The topical route delivers the active compound directly to the hair follicle environment while minimizing systemic absorption. Application involves a thin layer of gel spread across affected areas of the scalp. Androgenetic alopecia treatment (Phase 2 trial protocol) 0.05% gel Once daily Topical application to scalp
