    Letrone by Black Lion Research


    Put a stop to estrogen before it puts a stop to you!


    When it comes to any anabolic cycle, no one’s goal is to boost estrogen, grow man boobs, and lose definition, but the truth is that it can happen.


    It can happen, but there is a way to make sure it never happens!


    Black Lion Research presents quite possibly the strongest estrogen blocker/aromastase inhibitor available today with Letrone!


    Black Lion Research has consistently been an innovator, with every new product offering something no one has done before, and Letrone follows that same path and may quite possibly be the strongest estrogen blocker we have seen in a long time.


    The key ingredient of Letrone is Atractylodes Macrocephala - a natural anabolic aromatase inhibitor that aids in preventing your body from converting testosterone to estrogen - a common side effect of strong anabolic cycles.


    Additionally, the ingredient has anabolic properties meaning it can help to increase your natural hormone production and boost your testosterone - meaning you can run it by itself to get lean and shredded to the bone!


    An estrogen blocker designed to accelerate your fitness journey!

    Letrone Formula Explained:


    Atractylodes Macrocephala: a Chinese medicinal herb, has been extensively used to treat digestive diseases in China and most other Asian countries. In studies the ingredient has been exceptionally strong with 94.5% aromatase inhibition. Additionally, unlike many of the aromatase inhibitors on the market Atractylodes Macrocephala has shown to have exceptional oral bioavailability. In regards to anabolic properties, in animal studies subject experienced 20% more growth when compared to the placebo group which was attributed to increases in growth hormone of 30%, IGF-1 of 52%, T3 of 47%, T4 of 36%, and cAMP of 21%.

    Naringin: Some studies have suggested that naringin may have anti-estrogenic effects by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogens. This could potentially help reduce estrogen levels in the body. 

    Hesperidin: Hesperidin has shown some potential for estrogen reduction by acting as a selective estrogen receptor modulator (SERM). SERMs can bind to estrogen receptors, either blocking or activating them depending on the tissue type. In a study conducted on rats, hesperidin demonstrated estrogenic effects in bone tissue while showing anti-estrogenic effects in the uterus, similar to other SERMs. However, further research is needed to understand the full implications of these findings in humans and to determine the optimal dosage for potential estrogen reduction.

    Tangeretin: Tangeretin has been studied for its potential anti-cancer effects, particularly in estrogen receptor-positive breast cancer cells. In vitro studies have shown that tangeretin can inhibit the growth of breast cancer cells by modulating estrogen receptor signaling and suppressing the activity of proteins involved in cell proliferation. While these findings suggest that tangeretin may have a role in estrogen-related pathways, more research is needed to fully understand its effect on estrogen levels in the body.

    Bioperine®:Another essential ingredient aimed at optimizing the the effectiveness of the ingredients in Letrone. Bioprene is a standardized extract from the fruit of Piper nigrum L (Black Pepper) containing 95% piperine. Piperine has been shown to enhance the oral bioavailability of many supplements.
