RedCon1 Shield: Simple, Effective Protection From Estrogen

RedCon1 Shield

RedCon1 Shield is the ultimate anti-estrogen, anti aromatase formula good for preventing excess estrogen production both on and off cycle.

Moodiness, depression, bloating, man boobs and low sex drive.

These are all the common symptoms of low testosterone production and high estrogen production in men. Whether you’re coming off a prohormone cycle, or stressed out way too much with life, estrogen production can significantly ramp up, which stunts your testosterone levels.

But, there’s help on the way thanks to RedCon1.

Shield is a way to control the bloat and unwanted estrogen side effects whether you’re on or off cycle. It’ll put the clamps on aromatase and enhance the body’s natural testosterone production, making for bigger, better gains.

Meanwhile, it has just two ingredients for simple and effective anti-estrogen and liver support that can be used by nearly anyone.

Shield Ingredients

Shield is basic and effective aromatase inhibiting supplement powered by the most powerful suicidal AI on the market — Arimistane. Topping that is one of the more under-utilized liver protectors in the sports nutrition market, NAC.

Note: Doses listed below are based on 1 serving (i.e. 2 capsules).

  • N-Acetyl Cysteine (500mg)

    RedCon1 Shield Ingredients

    Shield is the protection you need against out of control estrogen production.

    N-Acetyl Cysteine (NAC) is the main substrate for glutathione in the body, which means that if you’re deficient in NAC, you won’t produce adequate amounts of glutathione, an important antioxidant. This buffering of glutathione is the primary mechanism through which NAC delivers its antioxidative and pro-liver benefits. Heightened levels of glutathione enable the liver to more effectively filter nasties that accumulate in your body, ultimately keeping you (and your liver) happy, healthy, and free from the effects of prohormones, oxidative stress, etc.[1,2,3]

    Livers love it… even when you don’t love your liver!

    And, in case you weren’t aware, NAC is an awesome hangover preventer! Taken alongside Vitamins C and B, your body has everything it needs to breakdown the alcohol you drink and its nasty, toxic byproducts like acetaldehyde.[6]

    Anyway, NAC is far too often ignored by athletes (it’s heavily used in other medical fields), and that’s a shame because it works so well for the liver. Glutathione is your liver’s favorite mop – give it the support it needs to make more!

  • Androsta 3,5-dien-7,17-dione (25mg)

    Estrogen Receptor 1

    Coming off cycle is when you’re particularly susceptible to having rampant estrogen production in the body. To help ensure you don’t run into this problem, RedCon1 includes the most powerful Aromatase Inhibitor (A.I.) legally available in Androsta 3,5-dien-7,17-dione, a.k.a. Arimistane.

    Arimistane is a metabolite of 7-Keto DHEA and extremely potent A.I.[4,5] It functions primarily as a suicide inhibitor decreasing the amount of androgens in your body that can convert to estrogen. Arimistane binds to the aromatase enzyme and produces a permanent reaction. FYI, Aromatase is an enzyme that converts androstenedione to estrogen. So the way it works is that you aren’t really attacking estrogen — you’re preventing your body from releasing the enzymes that help you create estrogen!

    That’s not all though, as arimistane also helps control estrogen by inhibiting the conversion from Androstenedione to Estrogen. Arimistane is also useful for controlling cortisol levels in the body, which further supports natural testosterone production and muscle building.

RedCon1 Coupon

Have you checked our new RedCon1 coupon and deals page to stay up to date on their latest promotions?

Take 1 serving (i.e. 2 capsules) with breakfast during your cycle and as part of your PCT program.

You can run this solo for a bit of an extra kick, or add during and after your Somal-1 cycle — but we still always recommend blood tests when taking prohormones to make sure estrogen isn’t too high.

When you take those blood tests, don’t be surprised to see testosterone go up with that estrogen going down!


Not every guy is keen to jump on the prohormone bandwagon, but what every guy does want is naturally higher free testosterone levels — it makes for bigger and better gains in the gym and the bedroom! Shield is great for those using prohormones, currently in PCT, or the average non-prohormone user looking to boost his body’s natural testosterone producing abilities.

With Shield, you’re protected against the nasty effects of too much estrogen and headed down the path of optimal testosterone production. Shield is a simple and effective way to get it done without bombarding yourself with too many ingredients.
