Description
This Somatrop-Lab anastrozole at 1 mg blocks aromatase competitively; unlike exemestane‘s suicide inhibition, effects are reversible. Monitor E2 every 4 weeks during use.
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.
Potential Side Effects
Primary risk: crashed E2 — joint pain, low libido, lethargy, brain fog. If these appear, drop dose immediately. Lipid impact modest. No hepatic toxicity.
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
Somatrop-Lab specialises in growth-hormone and peptide products with lyophilised format and strict cold-chain documentation.
Storage & Handling
Store in the original blister or bottle at 15–25 °C, away from direct sunlight, heat, and humidity. Oral preparations lose potency faster if exposed to moisture; keep the desiccant (if included) with the tablets. Keep out of reach of children. For research and educational purposes only.
