Anastrozole (Arimidex) is the gold-standard aromatase inhibitor for anabolic steroid users — a prescription-strength AI that controls estrogen conversion on cycles containing testosterone, Dianabol, Deca Durabolin, or any other aromatising compound. Managing estrogen is not optional on most cycles: unchecked aromatisation causes water retention, gynecomastia, mood swings, and fatigue that undermine both results and wellbeing.
For a standard Testosterone Cypionate cycle at 400–500mg/week, Anastrozole at 0.5mg EOD keeps estrogen in the optimal range without over-suppression. On higher-dose protocols or stacks that include Sustanon at blasting doses or Anadrol as a kickstart, dose may need increasing to 0.5mg daily. Bloodwork at weeks 4–6 confirms the correct individual dose — estrogen target is typically 20–40 pg/mL on cycle.
Anastrozole is preferred over Letrozole for most standard cycles due to its more predictable dose-response and lower risk of estrogen crash. For heavy aromatisation loads or acute gynecomastia reversal, Letrozole is available as a significantly more potent alternative.

Essential alongside any aromatising compound. Been using Anastrozole from here for a year. 0.5mg EOD keeps my estrogen exactly where I want it — no bloat, no mood swings, joints still feel fine. Genuine product, works reliably. Fast delivery, discreet packaging. Would recommend to anyone on cycle.

Bought Anastrozole here and confirmed it works via bloods — estrogen came down from 180 to 42pmol/L at 0.5mg EOD. That’s exactly the target range. Product is pharmaceutical grade quality. 4 stars because I’d prefer blister pack presentation but the product itself is legitimately effective.

On TRT and use anastrozole to keep E2 in check. Been ordering here for 18 months. Product is consistent and effective — bloods confirm this every time. The most important thing with an AI is consistent dosing and this delivers that. Delivery always fast, packaging discreet. Top supplier.

Anastrozole at 0.25mg ED on a Test blast. Estrogen controlled perfectly — no water, no sensitive nips, mood great. Product is genuine. I’ve tried cheaper alternatives before and they were clearly underdosed. This works. Price is fair, delivery is always within 3-4 days. Reliable.
