Description
Anastrozol 1 mg Prime — Anastrozole is the most commonly prescribed aromatase inhibitor in both medical oncology and athletic performance contexts. By selectively and reversibly blocking the aromatase enzyme, it provides precise control over estrogen levels — essential for preventing the estrogenic side effects of aromatizing steroid cycles. This formulation is dosed at 1 mg per unit.
Key Benefits
- Aromatase inhibitor — blocks oestrogen synthesis at the source
- Standard on-cycle AI for testosterone-based protocols
- Low dose (0.25–0.5 mg EOD) typically sufficient for 400–500 mg test
- Dose by bloodwork — sensitive E2 assay, target 20–40 pg/mL
- Crashing E2 feels worse than mildly elevated E2 — err on the low side
- Each unit dosed at 1 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 0.25–0.5 mg every other day on testosterone-based cycles. Titrate to bloodwork (sensitive E2 assay, target 20–40 pg/mL). Higher doses required only on aggressive 700+ mg/week test protocols. During PCT: not used (blocks oestrogen needed for LH signalling).
How It Works
Non-steroidal aromatase inhibitor. Binds and inactivates the aromatase enzyme (CYP19A1) that converts testosterone and androstenedione to estradiol and estrone. Reversible binding — effect disappears within days of stopping.
Pharmacokinetics
Plasma half-life approximately 50 hours. Every-other-day dosing produces stable serum and tissue levels. Steady-state in 7 days.
Cycle & Stacking Guide
Used on-cycle with aromatising compounds (testosterone, methandienone, oxymetholone). Start at 0.25 mg EOD, bloodwork at week 4, adjust. Never used during PCT — needed estrogen signalling for LH/FSH recovery.
Manufacturer Notes
Prime produces AAS and research chemicals at accessible price points. Each SKU ships with batch-code documentation through distributor channels.
Storage & Handling
Store at recommended temperature (15–25°C; peptides and HGH at 2–8°C after reconstitution). Protect from light and moisture. Keep out of reach of children. For research and educational purposes only.
