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.

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.

Frequently Asked Questions

Can I take LGD-4033 with Primobolan?

Combining LGD-4033 with Primobolan is not recommended. Both LGD-4033 and Primobolan 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 Primobolan safe together?

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

Both LGD-4033 and Primobolan 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 Primobolan?

LGD-4033 has a half-life of ~24-36 hours and Primobolan has a half-life of ~10 days (enanthate). 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 context

Read sources and limitations before applying a claim.

Research Indications

First-line pharmacotherapy for lifelong and acquired premature ejaculation. Clinically proven to increase intravaginal ejaculatory latency time (IELT), improve perceived control over ejaculation, and reduce personal distress related to PE. Improved ejaculatory control leads to greater sexual satisfaction for both the individual and their partner, as measured by validated patient-reported outcome instruments in clinical trials.

Research Indications

Primary mechanism activating dormant muscle satellite cells which fuse to damaged fibers. Increases proliferative lifespan in younger muscle progenitor cells. Increases activated satellite cell fusion capacity supporting repair and hypertrophy. Animal studies suggest improved Achilles tendon injury outcomes. Rabbit models demonstrated faster healing via osteoblast regulation. Research indicates potential for articular cartilage injury models. Naturally upregulated after mechanical stress; supplementation may enhance processes. Localized injection near injury sites supports targeted tissue repair.

Dosing Protocols

Dutasteride is administered as an oral soft gelatin capsule at 0.5mg. The capsules should be swallowed whole and not chewed or opened, as the contents may irritate the oropharyngeal mucosa. It can be taken with or without food. Due to its extremely long half-life of approximately 5 weeks, some users adopt a reduced-frequency protocol of 3 times per week while still maintaining significant DHT suppression. Steady-state blood levels are reached after approximately 6 months of daily dosing. Hair loss treatment (standard daily) 0.5mg Once daily Oral soft gelatin capsule Hair loss treatment (reduced frequency) 3x per week (e.g., Mon/Wed/Fri) Benign Prostatic Hyperplasia

Potential benefits

What are the cardiovascular benefits of B7-33 compared to other compounds?

B7-33 reduces myocardial fibrosis, enhances vasodilation through nitric oxide pathway, and demonstrates cardioprotective effects in heart failure models. These anti-fibrotic and vasoprotective properties position it for potential use in cardiac remodeling, though all current data is preclinical.
