Athletes and bodybuilders utilize prohormones to increase muscle growth and improve overall body composition.
Prohormones are sometimes referred to as “light steroids” because they do not directly impact the body yet provide the basic structure for increasing testosterone.
Thus, the primary purpose of supplementing prohormones is to increase your performance and body definition.
Prohormones are extremely powerful androgens with a basic function that is comparable to anabolic steroids.1
Moreover, many experts suggest that prohormones are more effective than Selective Androgen Receptor Modulators (SARMS) when it comes to rapid muscle and strength gains.
Additionally, prohormones are comparable to SARMS in that both compounds are considered far safer than consuming steroids.
The side effects are not nearly as extreme or dangerous yet clinical research is lacking to verify some of these claims.
Nevertheless, prohormones are trending in the right direction for those that desire to increase testosterone levels.
What are the 4 best prohormones for 2022?
Find out in our complete review of the top prohormones for testosterone production.
#1. 1-Andro Capsules
Note: Click Here to pick up 1-Andro legally from the official Behemoth Labz website.
Athletes and bodybuilders generally agree that prohormones stimulate muscle growth.2
Those that have supplemented prohormones in the past have witnessed significant strength and muscle gains.
More importantly, prohormones do not appear to produce near the same nasty side effects as anabolic steroids.
For this reason, 1-Androsterone is one of the most popular prohormones for daily supplementation.
The naturally occurring metabolite of DHEA converts to 1-Testosterone but not estrogen (unlike anabolic steroids).3
Furthermore, 1-Andro does not appear to negatively affect the liver or cholesterol levels (another cardinal sin of steroids).4
Those that supplement 1-Andro notice moderate gains in lean muscle and strength.
However, users generally do not witness rapid increases in size or weight because extra-cellular and intra-cellular water retention is minimal.
Consequently, many athletes often stack 1-Andro with other prohormones or SARMS.
The compound is versatile and stacks well with just about anything.
Lastly, 1-Andro is one of the easier prohormones for PCT with 8 and 16-week cycles.
The side effects are minimal yet because of the androgenic potency, the compound is sometimes linked to mild hair loss/baldness.5
Nonetheless, it’s always advised to research any compound before you introduce it to a weight stack.
1-Andro is generally stored in a sealed bag or contained and should get stored in a cool, dry location.

Stack 1-Andro With:
There are a variety of options to consider when building a new weight stack with 1-Andro.
Several experts recommend using 1-Andro because the prohormone functions well with a variety of other compounds.
Those that supplement 1-Andro may also want to consider 4-Andro (more information, below).
Secondly, Behemoth Labz offers a variety of SARM Support options including Sa-Hydroxy and Clomiphene capsules.
Those that prefer liquid consumption can also shop for many different options including SR9009 and Cardarine.
#2. 4-Andro Capsules
Note: Click Here to pick up 4-Andro legally from the official Behemoth Labz website.
4-Androsterone is chemically more like testosterone than 1-Andro, according to several sources.6
Consequently, the agent serves as a weak agonist of the androgen receptor.
The prohormone converts testosterone thanks to the enzyme 3-beta hydroxysteroid dehydrogenase (3bHSD).7
The half-life of 4-Andro is similar to 1-Andro which requires large and frequent doses to notice an anabolic effect.
For this reason, most bodybuilders prefer 4-Andro as a “wet compound” that performs well with bulking cycles and not so much when you are attempting to cut unwanted weight.
The typical dose for a 4-Andro cycle (not stacking with other compounds) is 1,000 mg divided into 3 separate doses.
Users do notice an immediate increase in energy, aggression, and strength thanks to the short half-life.
As a result, most suggest consuming 4-Andro prior to training and with a meal.
4-Andro is available from reputable suppliers like Behemoth Labz.
The affordable price includes a secure shopping experience, free shipping, and a money-back guarantee.

Stack 4-Andro With:
There are so many options for stacking 4-Andro with other prohormones or SARMS.
For starters, the capsule is frequently purchased with MENT / Trestolone Acetate liquid.
SARM Support is available through popular stack options like 1,4 DMAA Liquid, Tadalafil Citrate, and Clomid-Anastroz Mix.
Furthermore, Andarine S4 is one of the most common liquids to pair with 4-Andro.
Please keep in mind that all Behemoth Labz products are designed strictly for laboratory and research purposes.
Prohormones, like SARMS, still lack FDA approval which is common with many weight stack supplements.
In general, 4-Andro has only demonstrated mild to moderate side effects.
The reported side effects include acne, hair loss, and gynecomastia.
However, the estrogenic side effects are manageable if you use the compound with an aromatase inhibitor (AI).
Despite some concern about 4-Andro, the substance is not methylated and therefore poses no risk of stress on the liver, unlike anabolic steroids.
#3. 19 Nor-Andro Blend
Note: Click Here to pick up 19-Nor-Andro legally from the official Behemoth Labz website.
There is no secret why more athletes and bodybuilders are diverting from anabolic steroids and seeking higher quality, safer options.
Prohormones are trending in the right direction when it comes to muscle growth and improved strength.
There are several reported advantages of using prohormones to increase muscle mass:
- Muscle Growth
- Strength Gains
- Improved Mood
- Increased Libido
Additionally, prohormones are cheaper and produce fewer side effects compared to anabolic steroids.
Lastly, the oral method of intake (via capsules) is easier to dose and consume compared to injections (common with steroids).
19 Nor-Andro is another type of prohormone that can alter “muscle building” hormones like testosterone.8
Unfortunately, clinical research is insignificant regarding 19-nor-DHEA.
Moreover, not as much is known about the prohormone compared to 1-Andro and 4-Andro.
There was one 8-week study that analyzed the effects on body composition and athletic performance in random subjects.
The results of that study indicated no significant changes in exercise performance, mood, or body composition.9
19 Nor-Andro is available from brands like Behemoth Labz where two purchase options exist: 50mg/30ct/1.5g ($55.48) and 50mg/60ct/3g ($102.89).
Behemoth Labz seeks to stand behind its prohormones by providing exceptional customer service.
Therefore, if you are not fully satisfied with your order, contact the supplier at email@example.com.

Stack 19 Nor-Andro With:
Building a new weight stack is one of the more exciting steps in the process of a complete body transformation.
Often, bodybuilders stack prohormones with other substances such as Selective Androgen Receptor Modulators (SARMS).
The Behemoth Labz PreReactor capsules are a popular item to bundle with 19 Nor-Andro.
You can also shop for a variety of other SARM support options to stack with 19 Nor-Andro.
RAD 140 and S-23 Liquid are alternatives if you prefer combining capsules with liquid intake.
Lastly, Cycle It Capsules can help you achieve your Post Cycle Therapy (PCT) goals.
#4. Ostarine MK-2866
Note: Click Here to pick up Ostarine legally from the official Behemoth Labz website.
Ostraine MK-2866 is technically not a prohormone, but a Selective Androgen Receptor Modulator (SARM).
However, the two compounds have numerous similarities and therefore are often paired together in weight stacks.
While there are multiple other SARMS to consider when building a new stack, Ostarine MK-2866 is a decent place to begin.
The affordable SARM for muscle growth is available from reputable brands like Behemoth Labz.
You should only consider purchasing SARMS and prohormones from reliable manufacturers to make sure you are receiving a pure and potent substance.
Thankfully, Behemoth Labz offers a satisfaction guarantee with secure checkout and free shipping.
Customer satisfaction is their number one priority which is not always the case with cheap knock-off products.
While there is growing momentum in the bodybuilding industry to support SARMS, please keep in mind they remain unregulated by the FDA.
Clinical research is lacking for SARMS just like with prohormones like 1-Andro and 19 Nor-Andro.
Thus, Behemoth Labz only advertises its compounds for laboratory and research purposes.
You should always understand the risks associated when taking any new supplement or building a weight stack.

How Ostarine MK-2866 Functions with Prohormones:
Ostarine MK-2866 is one of the most popular SARMS for muscle growth.
Consequently, many bodybuilders utilize the substance as part of a bulking cycle.
The Selective Andron Receptor Modulator is linked to improving lean muscle and burning body fat.
However, like other prohormones and SARMS, clinical support is lacking to verify the safety and effectiveness.
As a result, most that build weight stacks rely on word-of-mouth reputation since the FDA refuses to acknowledge the validity of SARMS.
Ostarine was initially researched as a potential treatment for diseases that cause muscle atrophy or loss.
The close connection to anabolic steroids has caused the government to remain apprehensive in regard to approving Ostarine MK-2866.
However, MK-2866 and other SARMS are not known to produce near the severity of side effects on the body compared to steroids.
Ostarine MK-2866 performs is both a fat burner and lean muscle producer.
Therefore, the compound is effective as a “dry” and “wet” substance depending on weight loss or muscle building needs.
When paired with other prohormones in a weight stack, the benefits can even get enhanced with proper dosage.
Lastly, Ostarine MK-2866 may protect the body against muscle waste.
It’s why the substance is often stacked with other popular prohormones like 1-Andro and 4-Andro.

What Do Prohormones Do?
Prohormones are something to remain positive about even if the substance lacks complete federal approval.
While there are some concerns that prohormones are like anabolic steroids, most of those comparisons are related to how they influence testosterone levels.
In general, those that have supplemented prohormones in the past have not witnessed the severe and dangerous side effects associated with steroids.
Consequently, there is mounting support for utilizing prohormones to increase testosterone.
The hope is that “muscle building” supplements like prohormones can build muscle mass and burn fat in a healthy, effective, safe manner.
However, until more clinical research is conducted it’s difficult to reach a firm conclusion on word-of-mouth reputation alone.
Often, stacking prohormones with other compounds like Selective Andron Receptor Modulators (SARMS) can help you achieve fitness goals faster with the right approach.
Nonetheless, there are numerous factors that contribute to lean muscle and strength gains outside of supplementation.
