1-Androsterone Usage, Dosage, Benefits, Side Effects and Other Relevant Details


Every year, the main objective for most men and women is to gain lean muscle. You most likely want to replace that fat with lean muscle tissue, even if you want to burn fat and reduce weight. Prohormones may have appeared as the natural initial option for anyone looking for further muscle-building assistance in the form of supplements but who didn't want to use steroids.

Popular muscle-building prohormone androsterone promises significant increases in muscle growth and strength, but are these claims true? Can 1-androsterone truly aid in the development of lean muscle and the attainment of physical objectives?

Let's examine what Androsterone is, the possible advantages of 1-andro, and the adverse effects of Androsterone you should avoid.

What Is 1-Androsterone?

Vial containing 1-Androsterone

Androsterone (1-androstene 3b-ol, 17-one), sometimes called 1-androsterone or 1-andro, is a potent designer steroid recognized as 1-DHEA's metabolite. Androsterone is categorized as a prohormone, a category of dietary supplement, despite its connection to 1-DHEA. Similar to steroids, prohormones are intended to build muscle mass and burn fat, although some strength-based athletes also take them in the hopes of improving personal records.

Because of its capacity to increase muscle mass and decrease body fat, it is a common supplement used by bodybuilders and fitness enthusiasts.


Structure of 1-Androsterone

How Does It Work?

1-Andro is a prohormone that converts into 1-testosterone in the body. This conversion process is what makes 1-Andro a potent muscle builder. A study published in the Journal of Applied Physiology found that 1-Andro supplementation led to significant increases in lean body mass and strength in resistance-trained men.

Androsterone needs to be broken down by the liver after consumption. Here, it will get the enzyme it needs to transform into a steroidal molecule and foster anabolic effects. Because prohormones don't become active until they travel through the liver, some of them can avoid being classified as illegal steroids. Anabolic steroids, on the other hand, have an instant impact on your levels of testosterone and androgenic hormones and don't need an extra enzyme to do so.

Benefits Of 1-Androsterone

Benefits Of 1-Androsterone

When used as a part of a healthy diet and training program, 1-andro may promote the following benefits:

Muscle Growth

Muscle growth

1 A prohormone pill called Androsterone has significantly improved muscular hypertrophy or growth. It can greatly boost protein synthesis and nitrogen retention, two essential processes for muscle growth, by converting into 1-testosterone. According to studies, Androsterone proved effective in encouraging the growth of lean muscle. The body composition of the participants who completed a 4-week exercise program while taking 330 mg of 1-andro per day showed considerable changes. However, the researchers warn that the harm done to the body significantly surpassed the positives the patients experienced.

Fat Loss

Fat Loss

While many prohormone users require a bulking and cutting supplement, Androsterone appears to eliminate the requirement for separation. Many users claim to have burned a significant amount of body fat while also gaining lean muscular structure. As an anabolic chemical, 1-Andro may aid in fat loss by improving metabolic processes and generating a higher muscle-to-fat ratio. This can result in a more defined, slimmer body.

Strength Gains

Strength Gains

Users who have used 1 Andro believe that using Androsterone has enhanced their back squat and general workload. While the individuals' strength levels did rise, it is unclear if these increases were sustained. 1 Andro may help to increase strength and power by increasing muscle development and enhancing overall body composition. Users frequently report considerable gains in performance during resistance and strength training sessions.

Enhanced Recovery

1-Andro may also help to speed up muscle recovery and reduce muscular pain after intensive activity. This can result in more efficient workouts and faster progress towards fitness objectives.

Average 1 Andro Results

Individual reaction, dose, cycle duration, genetics, and adherence to good food and exercise routines are all elements that might affect the outcome of 1-Andro users. Most users may acquire 8 to 12 pounds of lean muscle while losing 4 to 6 lbs of body fat over the course of a 6- to 8-week cycle.

Users frequently report the following outcomes:

  1. Gained muscular mass
  2. Reduced body fat
  3. Increased power and performance
  4. Increased muscle recovery
  5. Increased lean muscular mass

Side Effects

Side effects of 1-Androsterone

Researchers discovered that prohormones had a variety of adverse effects, the most noticeable of which was a rise in estrogen levels. Because your body gets dependent on the prohormone to raise its testosterone levels, natural testosterone production in your body decreases. When your cycle is over, your body's estrogen levels will rise to match the increased testosterone levels.

Other potential androsterone side effects include the following:

  • Acne
  • Hair loss
  • Weight gain
  • Loss of muscle mass
  • Mood swings
  • Liver toxicity

How To Take 1-Androsterone

Administration of 1-Androsterone

A regular androsterone cycle should last 4 weeks. However, there have been anecdotal accounts of experienced users taking it for up to 8 weeks. The recommended beginning dose for novices is 300 mg per day, and the highest dosage is 1,000 mg per day, although this is only for users who have completed numerous cycles of 1-andro.

If you've never used a prohormone before, it's best to start with a modest dose and gradually raise it each week. Here's a breakdown of a beginner-friendly 1-androsterone dosing schedule:

  1. Week 1: 200 mg
  2. Week 2: 250 mg
  3. Week 3: 300 mg
  4. Week 4: 325 mg

Importance of PCT (Post Cycle Therapy)

 PCT and 1-Androsterone

PCT is an essential component of every prohormone cycle, including 1-Andro. PCT aids in the restoration of the body's natural hormonal balance while minimizing the potentially harmful side effects of prohormone use. Selected estrogen receptor modulators (SERMs) and natural testosterone boosters are commonly used in PCT regimens.

It aids in the restoration of your natural testosterone production at the end of your cycle. This helps to secure your hard-earned benefits while limiting or eliminating adverse effects. Oestrogen Blockers are another useful strategy for preventing negative effects. The PCT has the following effects:

  • Restores Natural Testosterone Levels
  • Detoxifies Your Body
  • Increases Libido 
  • Improves Immune Function 
  • Aids in the Prevention of Side Effects 

Dosage and Cycle Suggestions and Time

Typical Dosage Range

The typical daily dose of 1-Andro is 300-600 mg, split into two or three doses during the day. Starting with a smaller dosage and progressively increasing it based on individual tolerance and outcomes is critical.

Cycle Duration

A normal 1-Andro cycle lasts 6 to 8 weeks for inexperienced users and 8 to 10 weeks for expert users. Longer cycles are typically not suggested because of the increased risk of adverse effects and testosterone suppression.


Many people find it helpful to divide their daily dosage in half and take half in the morning and half in the evening. Some people like to take one of their dosages before a workout to give them an added boost.

Stacking with Other Supplements

1-Andro can be used with other supplements to achieve the best effects.

  1. DHEA supplements such as 4-Andro, Epi-Andro, and Androsterone are common 1-andro stack supplements.
  2. Pre-workout formulations for increased energy and concentration during workouts
  3. BCAAs (branched-chain amino acids) for muscle repair and development
  4. Creatine to boost strength and performance
  5. Natural testosterone supplements to help maintain hormonal balance during PCT


1-Androsterone: Conclusion

Because of its potential benefits in muscle development, fat reduction, strength increase, and recuperation improvement, 1-Andro is a popular prohormone among fitness enthusiasts and bodybuilders. While it is thought to be gentler than other prohormones, it still has possible side effects and hazards that must be evaluated against the advantages. Proper dose, cycle duration, cycle support, PCT, food, and exercise are all key components for maximizing 1Andro efficacy while minimizing potential side effects.

Individuals may make educated decisions about whether 1-Andro is the appropriate choice for them by examining the facts offered in this guide. Always seek the advice of a healthcare expert and adhere to suitable recommendations to achieve the greatest potential outcomes while minimizing the hazards connected with prohormone usage.
