Compound Profiles

Anastrozole

Aromatase Inhibitor | Estrogen Management

Anastrozole competitively binds to the heme group of the aromatase enzyme (cytochrome P450 19A1), reversibly inhibiting its catalytic activity. Aromatase is responsible for the final step in estrogen biosynthesis, converting testosterone to estradiol and androstenedione to estrone in peripheral tissues including adipose, muscle, liver, and brain.

Proviron

DHT Derivative | Mood, Libido & Muscle Hardening

Proviron exerts its effects primarily through direct binding to the androgen receptor (AR) as a potent DHT analogue. However, its most therapeutically relevant mechanism is its exceptionally high binding affinity for sex hormone-binding globulin (SHBG).

Frequently Asked Questions

Can I take Anastrozole with Proviron?

Yes, Anastrozole and Proviron can generally be taken together. Proviron's mild anti-estrogenic effect through aromatase competition can reduce the required dose of anastrozole or other aromatase inhibitors. In many men on standard TRT doses, adding Proviron at 50 mg/day eliminates the need for an AI entirely. When both are used, monitor estradiol to avoid over-suppression, which impairs lipids, joint health, bone density, and libido.

Is Anastrozole and Proviron safe together?

Based on documented research, this combination is considered compatible. However, shared safety flags include: androgenic, aromatase inhibitor, hepatotoxic, hpta suppressive, lipid disrupting, teratogenic. Monitor accordingly.

What are the interactions between Anastrozole and Proviron?

Proviron's mild anti-estrogenic effect through aromatase competition can reduce the required dose of anastrozole or other aromatase inhibitors. In many men on standard TRT doses, adding Proviron at 50 mg/day eliminates the need for an AI entirely. When both are used, monitor estradiol to avoid over-suppression, which impairs lipids, joint health, bone density, and libido. This assessment has 90% confidence and is based on documented research data.

How should I time Anastrozole and Proviron?

Anastrozole has a half-life of ~40-50 hours and Proviron has a half-life of ~12 hours. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.

Research Indications

RAD-140 has shown potent anabolic effects on skeletal muscle in preclinical models, with increases in lean body mass comparable to moderate doses of testosterone. Users report meaningful increases in lean mass over 8-12 week cycles at 10-20 mg/day, though controlled human trial data for this indication is lacking. Dose-dependent increases in strength have been reported anecdotally and are consistent with the compound's mechanism of action as a potent AR agonist in skeletal muscle. Strength gains are typically noticed within 2-4 weeks of starting a cycle. The combination of anabolic activity without estrogenic water retention makes RAD-140 a compound of interest for simultaneous fat loss and lean mass gain. Preclinical data supports a favorable shift in body composition, though human data is limited. RAD-140 has entered Phase 1 clinical trials for the treatment of ER+/AR+/HER2- metastatic breast cancer. The rationale is that AR activation can suppress estrogen-driven tumor growth in AR-positive breast cancers. Early results demonstrated tolerability and preliminary signals of anti-tumor activity. Originally developed for conditions involving muscle wasting (cachexia, sarcopenia, age-related muscle loss). Preclinical data supports the potential to preserve or restore muscle mass in catabolic states, but no human efficacy trials have been completed for this indication. In vitro studies have shown that RAD-140 protects hippocampal neurons from kainate-induced excitotoxicity and beta-amyloid-induced cell death, suggesting potential relevance to neurodegenerative diseases. This remains a preclinical observation only.

Dosage reference

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
