If you've been trying to restock on your favorite anti-estrogen or post cycle therapy staples recently, you may have run into a frustrating wall, Hi-Tech Arimistane is currently on backorder.
Over the past weeks of Arimistane being backordered other popular Aromatase Inhibitors aka Estrogen Blockers such as Muscle Addiction Eradicate E and Blackstone Labs Eradicate have also been going out of stock, as have many PCT supplements containing Arimistane.
While the situation isn't clear, rumors on Reddit state that Arimistane has been banned in China. It's potentially always been banned but not enforced, but it appears Arimistane isn't making it out of China causing ingredient shortages for prohormone manufacturers.
Whether you're wrapping up an intense cycle or simply looking for an everyday aromatase inhibitor to keep water retention low and muscle density high, waiting weeks for a backordered stock isn't an option. Hormonal balance doesn't wait around for supply chain delays.
The good news, You don't have to wait. If you are looking for a reliable hard hitting and highly effective substitute, Blackstone Labs Letro XT is officially taking the crown as the #1 alternative to Arimistane. We also have Hi-Tech Estrogenex in stock as well.
Here is a look at what makes Letro XT stand out, the exact compounds inside its formula and why it might actually outshine standard Arimistane.
Why is Everyone Switching to Blackstone Labs Letro XT?
While Arimistane (Androsta 3,5-diene-7,17-dione has long been a go to OTC aromatase inhibitor, Letro XT takes a varied approach to estrogen control.
Instead of just relying on a single compound, Blackstone Labs stacked two powerful synergistic suicide aromatase inhibitors into one formula, ATD and 6-Bromo.
Letro XT Ingredient Breakdown
Letro XT features a 75mg Proprietary Anabolic & PCT Blend driven by two clinically proven ingredients.
3b-hydroxy-androsta-1,4,6-triene-17-one (ATD)
Common Name: ATD (1,4,6-TAT)
What It Does: ATD is a powerful non-steroidal suicide aromatase inhibitor. It permanently binds to the aromatase enzyme, the exact same enzyme responsible for converting excess testosterone into estrogen. By shutting down this pathway, ATD stops estrogen biosynthesis right at the source, preventing estrogen from rebound and signaling your HPTA axis to kickstart natural testosterone production
3b-hydroxy-androsta-4,6-diene-17-one (6-Bromo)
Common Name: 6-Bromo (6-BD)
What It Does: Working hand in hand with ATD, 6-Bromo is another heavy duty aromatase inhibitor that actively targets circulating estrogen levels. It prevents fluid accumulation, reduces subcutaneous water bloat, and supports key gonadotropins like Luteneizing Hormone (LH), which is crucual for full hormonal recovery post cycle.
