Hi-Tech Prohormones – The Deca Stack by Jim Brewster

Hi-Tech Decabolin Halodrol Arimistane Stack

When it comes to prohormones, there are quite a few choices still left on the market. Many of these choices belong to the Hi-Tech family of products. Recently, I have looked at individual prohormones made by Blackstone Labs. They are part of the Hi-Tech family. With that in mind, this time I will look at Hi-Tech prohormone stacks and review a stack that looks to be not only popular but very effective: the Deca Stack! Needless to say, this is the first of several Hi-Tech prohormone stacks I will be detailing. Look for upcoming articles!


What Are Prohormones

Having said that, let’s start with a quick review. What are prohormones? They can be defined as  “a precursor of a hormone, such as a polypeptide that is split to form a smaller polypeptide hormone or steroid that is then converted to an active hormone by the process of metabolism” (1). In other terms, a prohormone is an ingredient that goes through a process in the body that allows it to change into an anabolic hormone. Prohormones are similar to but milder than anabolic steroids. Additionally, there are no serious side effects. 


You can expect the following benefits:

  • Gains In Lean Muscle
  • Strength Increases 
  • Improved Recovery
  • Fast Fat Loss – if that is your goal. If not, you will still lose fat, but it will not be as dramatic. 

The Hi-Tech Deca Stack!

I’m naming this stack the Hi-Tech Deca Stack because their Decabolin is the centerpiece of this combination.

What Is The Hi-Tech Deca Stack

Hi-Tech Decabolin

Decabolin provides 75mg 19-Nor-Andro per tablet. 19-NorAndro – This compound is also called 19-Nor-DHEA and NorAndrost-4-ene-3b-ol, 17-one. 19-NorAndro converts to nandrolone. This compound is similar to the popular steroid Deca Durabolin. It’s a “dry” compound. This means any potential side effects will be mild. 


What can you expect from a cycle of 19-Nor-Andro? Most users can expect lean, dry gains of 4-8 lbs. 


  • Promotes Hard, Dry, Lean Muscle Mass
  • Increases Strength 
  • Easy To Stack With Other Hi-Tech Prohormones 
  • Features Cyclosome Delivery Technology For Enhanced Absorption


Hi-Tech Halodrol

Originally, Halodrol was a prohormone carried by Gaspari Nutrition. They went bankrupt in 2014 and were bought by Hi-Tech 2 years later. Currently, there’s no mention on either site of Gaspari being owned by Hi-Tech. Nonetheless, Halodrol is one of the more potent prohormones on the market. One serving of 1 capsule contains a 250mg “Proprietary Anabolic Blend” of 1-Androstene-3b-ol, 17-one, 4-Androstene-3b-ol,17-one, Androsterone, Androstenolone Acetate, and Rhaponticum Carthamoides 100:1 Extract. 


What can you expect from a cycle of Halodrol? Like other prohormones, most users can expect lean, dry gains of 4-8 lbs. 


  • Formulated with Anabolic Agents, Including Legal Prohormone Esters
  • Amino Acid Catalytic Converter and Promotes Protein Synthesis
  • Natural Steroidal Anabolic and Anti-Proteolytic Formulation
  • Boost Testosterone Levels and/or Enhance Athletic Performance


Hi-Tech Arimistane

Even if the gains are dry and there’s limited toxicity, it makes sense to take a product that inhibits estrogen and cortisol. One serving provides 50mg Androsta 3,5-dien-7,17-dione (as Arimistane). This can be taken in-cycle and as part of your PCT.

  • Helps Block Estrogen & Cortisol
  • Provides Cardiovascular Support
  • Elevate Testosterone Levels
  • Helps Restore Liver Enzymes
  • Prostate Support and Protection

How Do I Use It?

Take these products as directed on the labels. Read all label directions before using. 

What About A PCT?

As mentioned, you can take Arimistane during and post-cycle. You should also take a PCT such as Blackstone Labs PCTV. Blackstone Labs is a member of the Hi-Tech family of brands. I also advocate making sure your supplement arsenal is in place, especially at the end of a cycle. I would take an additional test booster, such as Spazmatic Labs Just Test Me. I would also be sure you’re taking enough protein, as well as a BCAA/EAA to maximize protein synthesis. I’d probably add creatine if you’re not using it already.

Hi-Tech Prohormone Stack: What Kind Of Results Can I Expect?

You might see claims of 10-20lbs of mass online. Of course, age matters, your training matters, and your diet matters. If you’re eating and training to gain, I would expect 10-12lbs from a stack like this. The key is, you won’t keep all that post-cycle. Typically, you may lose up to 50% of your gains. This means that you may see a net gain of 5-6lbs. Since we’re talking on-the-edge natural, that’s not bad at all. 


What About Training & Nutrition?

Some may recommend cutting back on load and instead, increasing volume while on a cycle. You could also increase intensity techniques. Then post-cycle, when you’re fighting hormonal imbalances and trying to keep your gains, pushing your loads up to your pre-cycle level and using progressive resistance will help you keep your gains.


During the cycle, you can up your protein and carbs. I suggest doubling protein intake. So, for example, you are currently ingesting 150g per day. Double it to 300g. You might have to add a couple of small shakes and increase protein per meal to hit that number. 


I also suggest doubling carbs, unless you are already eating a high-carb diet. In that case, increase carbs by 50%. Also, keep your carbs low glycemic, with simpler carbs around the workout hours. 


Post-cycle, drop carbs back to pre-cycle levels but reduce intake high. If you keep carbs under control, you will stay lean post-cycle. Don’t drop protein back all the way. If, as in our example, you doubled your protein to 300 grams, cut it back to 175-180g. Fat intake should always come from healthy sources and comprise no more than 20% of total calories. 

To Sum Up

You can get all the products mentioned right here at illpumpyouup.com. When you pick up your stack products, make sure you have enough to run an 8-week cycle. Make sure you have enough PCT products to run an 8-week cycle. Finally, don’t forget your protein powder and pre-workout.
