Blackstone Labs Letro XT – Hardcore Estrogen Control & PCT Support (60 Tablets)

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. Beginners should approach prohormones with caution, as these compounds are more suitable for advanced athletes who understand the risks.

Ingredient Breakdown (per tablet) of Letro XT

Proprietary Anabolic & PCT Blend – 75 mg

• 3b-hydroxy-androsta-1,4,6-triene-17-one

This compound is a highly potent aromatase inhibitor (AI) that blocks the enzyme aromatase, which converts testosterone into estrogen. Inhibiting this conversion helps lower circulating estrogen levels in the body, reducing the risk of estrogen-related side effects such as water retention, bloating, gynecomastia, and fat gain. This AI is often used during or after prohormone/SARM cycles to keep estrogen under control and maintain a hard, dry physique.

• 3b-hydroxy-androsta-4,6-diene-17-one

Another advanced aromatase inhibitor, this ingredient works synergistically with the first to further enhance estrogen suppression. It helps stabilise hormonal balance during post-cycle therapy and is effective in preventing estrogen rebound, which can occur when estrogen surges after coming off the cycle. Additionally, it supports a favorable testosterone-to-estrogen ratio, which is critical for muscle preservation and strength retention during PCT.

These ingredients are potent aromatase inhibitors, designed to suppress estrogen at the enzymatic level.
By blocking the aromatase enzyme, Letro XT significantly reduces estrogen conversion, helping promote a leaner, more complex, and more defined look while supporting testosterone levels.
