When it comes to estrogen suppression, nothing works better than Blackstone Labs Letro XT. This powerful aromatase inhibitor is designed to eliminate estrogen, making it perfect for athletes undergoing intense cycles or experiencing high estrogen side effects such as water retention, gynecomastia, or persistent fat.
Letro XT combines advanced anti-estrogen compounds in a liposomal delivery system for enhanced absorption and faster results. Whether used during a cycle or as part of post-cycle therapy (PCT), it helps optimise hormonal balance, dry out your physique, and protect hard-earned gains.

Not for beginners — this is a hardcore anti-estrogen with real potency. Use responsibly.
Blackstone Labs Letro XT is a hardcore estrogen control and PCT support supplement in 60 tablets. It is designed to suppress estrogen through potent aromatase inhibition, making it suitable for athletes on intense cycles or those managing high estrogen side effects such as water retention or gynecomastia.
An aromatase inhibitor blocks the enzyme aromatase, which converts testosterone into estrogen. By inhibiting this conversion, Letro XT helps reduce circulating estrogen and maintain a more favourable hormonal profile during or after a cycle.
Key benefits include potent estrogen suppression, reduced water retention, protection against estrogen-related side effects, and post-cycle hormonal rebalancing. It can be used both on-cycle and post-cycle.
Take one tablet daily, preferably with food. For cycle support or PCT, use for 4–6 weeks unless otherwise directed. It can be used on-cycle to manage estrogen or post-cycle to prevent estrogen rebound.
It is designed for athletes and bodybuilders undergoing prohormone or advanced supplement cycles who need to manage estrogen levels or use a PCT support product. Intended for healthy adult males.
Letro XT is a hardcore aromatase inhibitor and is best suited to experienced users familiar with cycle-based supplementation. Beginners should consult a healthcare professional before use.
Yes, Letro XT is specifically formulated for both on-cycle estrogen control and post-cycle support. It helps prevent estrogen rebound and supports hormonal recovery after a cycle.
Each tablet contains the Proprietary Anabolic & PCT Blend (75mg) including 3b-hydroxy-androsta-1,4,6-triene-17-one as the primary aromatase inhibitor, plus additional PCT support compounds. Full details are on the product label.
