Compound Profiles

LGD-4033

Selective Androgen Receptor Modulator | Lean Mass

LGD-4033 binds to the androgen receptor with high affinity (Ki of approximately 1 nM), functioning as a potent and selective agonist in muscle and bone tissue. Like other SARMs, its tissue selectivity is mediated by differential cofactor recruitment: upon binding to the AR, LGD-4033 induces a receptor conformation that preferentially recruits coactivators expressed in skeletal muscle and bone, while showing minimal agonist activity in androgen-sensitive tissues such as the prostate and skin.

Tamoxifen

Selective Estrogen Receptor Modulator | PCT & Breast Cancer Treatment

Tamoxifen competitively binds to estrogen receptors (primarily ERalpha) and exerts tissue-selective effects depending on the local coactivator and corepressor environment. In breast tissue and the hypothalamus, tamoxifen acts as an estrogen antagonist, blocking estradiol-mediated signaling.

Frequently Asked Questions

Can I take LGD-4033 with Tamoxifen?

Combining LGD-4033 with Tamoxifen is not recommended. Both LGD-4033 and Tamoxifen carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.

Is LGD-4033 and Tamoxifen safe together?

This combination carries significant risk. Both LGD-4033 and Tamoxifen 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 LGD-4033 and Tamoxifen?

Both LGD-4033 and Tamoxifen 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 64% confidence and is inferred from pharmacological mechanism analysis.

How should I time LGD-4033 and Tamoxifen?

LGD-4033 has a half-life of ~24-36 hours and Tamoxifen has a half-life of ~5-7 days. 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.

What's the dose range for cognitive enhancement versus being too much?

The cognitive 'sweet spot' is 0.5-2 mg/kg body weight (roughly 35-140 mg for a 70 kg person). Doses above 2 mg/kg often shift from antioxidant to pro-oxidant effects, becoming counterproduc…

Community Research

Join others researching CJC/IPA Protocol — share findings, ask questions, and learn from real experiences A dual-pathway protocol combining CJC-1295 and Ipamorelin that targets growth hormone secretion through complementary mechanisms. CJC-1295 demonstrates 2-10 fold GH increases with 6-8 day duration, while Ipamorelin provides selective GH release without cortisol elevation. CJC-1295 activates GHRH receptors via albumin-binding DAC technology for sustained elevation. Ipamorelin selectively activates ghrelin receptors (GHSR1a) without affecting ACTH/cortisol, preserving natural pulsatile GH patterns.

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.

Dosing Protocols

Proviron is administered exclusively as an oral tablet, typically available in 25 mg tablets. Unlike most oral anabolic steroids, Proviron is not 17-alpha alkylated and instead relies on its 1-methyl DHT structure for oral bioavailability. This makes it one of the safest oral androgens with respect to liver toxicity. The 12-hour half-life supports once or twice daily dosing for stable blood levels. Low Dose - Libido and Mood Support 25 mg/day Once daily Oral Standard - TRT Adjunct 50 mg/day 25 mg twice daily (morning and evening) Higher Dose - Enhanced Protocol 75 mg/day 25 mg three times daily
