Why

Blackstone Labs Letro XT is a great way to naturally increase anabolic effects that will help you to gain muscle mass. If you have recently used a prohormone or SARM, it is important to perform a PCT. Letro XT has HPTA up-regulating effects that help to normalise natural testosterone levels whilst decreasing excess estrogen in the body. The only downside would be it is so focused on estrogen that it could probably be complemented by a product that enhances anabolism via a different pathway such as Adamantine and X-Factor or else a testosterone booster which specifically targets increasing free testosterone levels such as DS Activate Xtreme.

When

Letro XT can be used following a prohormone or AAS cycle as well as as a standalone muscle builder where its dual-action effect of lowering estrogen and boosting test can make it ideal for those on a recomposition cycle or a lean mass cycle. It will help support testosterone, minimise water retention and obviate the risk of estrogen related side effects by lowering the potentially high levels of estrogen that occur post cycle.

Who

Letro XT is the ideal supplement for individuals following a prohormone cycle in order to normalise hormone levels. This product, due to its ability to reduce estrogen and inhibit the aromatase enzyme should only be used by males over 21, and is not intended for use by women.

Predator Nutrition Letro XT Review

Letro XT is an all in one PCT formula and testosterone booster that is designed to help you normalise hormones following a prohormone or AAS cycle. Following your cycle, your natural testosterone levels will be very low, but your estrogen will remain within range of normal levels. If the ratio of testosterone to estrogen favours estrogen, this can cause unwanted side effects such as gyno, reduced strength and decreased ability to build muscle.

This is where Letro XT can help. Using non-androgenic testosterone boosters, Letro XT will help shift the balance back in favour of testosterone and in favour of anabolism. Letro doesn’t have any androgenic metabolites that could cause HPTA (hypothalamic pituitary testes axis) suppression. This make it an effective supplement for anyone seeking a PCT supplement that targets estrogen minimisation especially. 

INGREDIENT OVERVIEW

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

This is an aromatase inhibitor that permanently binds to the aromatase enzyme. In studies, this reduces estrogen biosynthesis and significantly increases the levels of endogenous steroids such as DHT and testosterone in humans. It has a prolonged half life which means you only need to take it once a day, unlike other anti-estrogens.

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

This compound is another AI that binds permanently to the aromatase enzyme, effectively stopping the conversion of testosterone to estrogen.

Androsta-3,5-Diene-7,17-Dione

This powerful product also known as Armistane, works by decreasing circulating levels of estrogen in the body. It helps to reduce the amount of androgens in the body that can convert to estrogen through aromatase enzymes. Fans of this compound alone may prefer to consider Fusion Supplements Arimistane in case they feel Letro XT suppresses estrogen too much (which can cause a negative effect on mood and joint integrity to name a couple of sides associated with very low estrogen).
