Letrone dosage & how to use
Take one (1) capsule 1-2 times daily. For healthy adult males over the age of 21 only. Do not take if you have any pre-existing medical conditions. Do not exceed the recommended dose.Product Guide
Why
Black Lion Research's Letrone is a potent aromatase inhibitor with powerful anti-estrogenic effects. This helps with lowering fat and water retention as well as increasing muscle density. It also enhances natural production of testosterone, HGH, and IGF-1, complementing and enhancing its anti-estrogenic qualities.
When
You can either use this as a standalone or as part of PCT. If using as a standalone it should be cycled, as you would with any other estrogen blocker. Letrone's combined anti-estrogenic and anabolic properties make it ideal for use as part of a PCT stack, but we would still recommend including a separate, dedicated testosterone booster alongside for optimal results.
Who
Letrone is a powerful product for the experienced bodybuilder. It is an ideal product for prohormone users for use as part of your PCT. Like all hormonal products this is most suitable for males over the age of 21.
Predator Nutrition Letrone Review
Oestrogen blockers are a standard part of PCT after a prohormone cycle, but they can also be used for leaning out and promoting a lean, hard, 'dry' figure. Black Lion Research's Letrone is a powerful aromatose inhibitor (AI) and an excellent oestrogen blocker.
Letrone is based on Atractylodes macrocephala, a herb based compound which has been shown to reduce aromatase by as much as 94%. Black Lion Research claim that this compound has greater bioavilability, and thus greater effectiveness, than other rival compounds.
What makes Letrone particularly interesting in our view though is its promised anabolic effects. Aside from its clear potential as an AI, Atractylodes macrocephala has been shown in one study to increase endogenous hormones. Simply speaking, this means it increases levels of your body's natural muscle building hormones, boosting testosterone, HGH, and IGF-1 - all hugely important compounds for bodybuilders.
All of this gives it significant anabolic potential, meaning that it offers benefits above and beyond a standard oestrogen blocker. Whilst the studies used by Black Lion Research were all conducted on animals rather than humans, the results look promising in terms of their potential to deliver real world results for bodybuilders.
All told this looks like an excellent product that will work well either as standalone or as part of a PCT stack.
