Hi-Tech Pharmaceuticals Arimistane Estrogen Blocker & On Cycle Support

This Estrogen Blocker goes hand in hand with Hi-Tech prohormones.

Hi-Tech's Arimistane PCT is one of the most powerful PCT's and Estrogen Blockers on the market, and is a great way to finish off your ProHormone Cycle. Arimistane was formulated to help limit Estrogen while also supporting healthy Testosterone levels when you're coming off of a ProHormone Cycle, in an effort to maintain the gains you made while on cycle. You spend a lot of money on ProHormone Cycles and put a lot of time and effort in at the gym to get those gains. Make sure you keep them by taking Hi-Tech Pharmaceuticals Arimistane for your post cycle support (PCT).

Arimistane Cycle Support vs Arimiplex PCT

Hi-Tech Arimistane Customer Reviews | What Customers Have To Say...

I bought Arimistane to help keep estrogen down and prevent gyno. Love how Arimistane works and I've noticed a huge reduction in water retention and less anxiety. Will definitely be buying again.

Feeling less tired and bloated than normal coming off my cycle. The wife is enjoying the increased libido ;)

This is my go to support while on a prohormone cycle as well as coming off. Definitely helps with mild gyno and I've noticed I'm leaning out really well. Muscle gains seem to be maintained better while off cycle, I'm definitely noticing more muscle fullness.

REALLY effective at controlling estrogen and cortisol. 

How Does It Work?

 Androsta 3,5-dien-7, 17-dione - This is a potent aromatase inhibitor, perhaps the most potent one you can get. Controls estrogen in the body.

Is Arimistane a ProHormone?

Arimistane is not a base ProHormone, Arimistane should be used in addition to other ProHormones like 1-Testosterone, 1-AD, Superdrol, Anavar, and others. 

Is Arimistane Liver Toxic?

Today's ProHormones are non-methylated and therefore not liver toxic, however we do recommend our customers take liver support with any prohormone cycle. This could be something like APS Nutrition Liver-MD or Hi-Tech Pharmaceuticals Liver-RX.

Does Arimistane Work?

Arimistane is an aromatase inhibitor meaning it will help lower estrogen levels when you are on cycle, helping to keep estrogen levels in check and prevent Gyno.

Can I Buy Arimistane on Walmart, eBay, or Amazon?

No, these platform sites typically do not sell more hardcore pre-workouts and fat burners let alone products like prohormones and pct's. 

Will Arimistane Help Prevent Gyno?

Arimistane is an aromatase inhibitor which aims to help lower estrogen, so many users use Arimistane to help prevent Gyno.

There are people who take too much Arimistane, if you do this it could cause your estrogen levels to crash leading to side effects like decreased sex drive, increased fat, and tiredness or fatigue. If you take the recommended dosage you shouldn't experience these issues. 

Can I Take Arimistane By Itself?

While Arimistane is often used as a on cycle support you can take Arimistane as a stand alone supplement. While it's not considered a ProHormone and is intended to be used alongside a ProHormone, if you're looking to lean out or are having issues keeping your estrogen in check you can take Arimistane as a stand alone supplement. 

Can I Stack Arimistane With Other Supplements?

It works awesome

I’ll be honest with this. I am stacking with my Test cycle of sust and dbol. Water retention and gyno are a real damn thing fellas. But I caught wind of this product through research to find a way to control water and sides. Takes about a week to see full effect of product but damn…nice n dry looking. Water is gone. This is damn good product. I’m impressed it can keep up with the big products out there as in testosterone. Wish I new about this a long *** time ago. But stay healthy brothers. Watch that water retention.

Best Arimistane

Great product for PCT. I did my research and HI Tech has the best quality & made in America. I did compare with another brand from another vendor and HI Tech is the best. I will continue to buy from Best Price Nutrition for PCT and also to it to keep my Estrogen levels low.

Seems to do what it should do without noticeable side effects (for me)

A lab report taken verified the effect on my E1 and E2 levels after 2 weeks of intake. I didn't notice side effects. Let's hope it stays around for whatever your individual needs might be.

Good for keeping water retention and helps dry you out but you need to use it for 12 weeks on 4 weeks off my experience works best for me.

One of the best supplements high-tech has to offer besides dymethazine but less sides than epi andros

Yep, it works

Great experience, if you’re atom tolerant. I keep energy and focus all day even on restricted calories. And it certainly helps with that as it kills appetite. I found myself setting a calendar alert to eat something or I’d forget.
