What is 1-Andro?

1-Andro is a prohormone that is converted by the body into 1-testosterone. 1-Andro is known by many names, including 1 Androsterone, 1-DHEA, 3b-hydroxy-androst-1-ene-17-one, etc.

In a double-blind placebo-controlled trial, the effects of 1-Andro on body composition, muscular strength, and other body parameters were measured. Seventeen resistance-trained men were assigned to receive either this prohormone or the placebo for four weeks.

Results from the study show that 1-Andro may potentially increase lean body mass, decrease fat body mass, and enhance strength in the men’s back squat.

The prohormone group also potentially improved their bench press and deadlift strength over the course of the trial. [R]

How does 1-Andro Work?

Health experts state that 1-Andro could be changed by the body into other hormones. Some of these hormones are very similar to testosterone. In particular, 1-Andro may be converted by the body to 1-testosterone, a potent androgen with anabolic properties. [R][R]

It has been claimed that 1-Andro undergoes a 2-step conversion process before being converted into 1-testosterone. However, more evidence is needed to verify or refute this assertion.

1-Andro Research

Only one clinical trial has been conducted on 1 Andro to date. Results from the trial indicate that this prohormone could potentially preserve muscle mass and increase its growth. Furthermore, it was established that 1 Andro could potentially improve muscular strength and bring about other resistance training gains.

1. 1-Andro and Muscle Growth

In its only clinical trial, 1-Andro showed potential increases in lean muscle mass in seventeen healthy participants. All the study subjects were resistance-trained men on a proper diet. They were randomly assigned to receive either 330mg/day of 1-Andro or sugar (placebo). [R]

Body composition, muscular strength, circulating lipids, and liver and kidney dysfunction markers were assessed at study onset and determination. It was found that this prohormone had the potential to increase the body’s lean mass by 6.3+-1.2% compared to the results brought about by the placebo.

2. 1-Andro and Fat Loss

In the above-mentioned clinical trial, the effects of 1-Andro (3β-hydroxy-5α-androst-1-en-17-one) on the body fat mass were also observed. It was found that this prohormone could potentially decrease fat body mass by 24.6 +- 7.1% among the seven resistance-trained men enlisted for the study.

These improvements exceeded that brought about by the placebo, which reduced fat body mass by 9.5+-3.6%. It is to be noted that the participants in the prohormone and placebo groups did not differ in fat mass at the study’s onset.

3. 1-Andro and Muscular Strength

The double-blind placebo-controlled trial also investigated the effects of 1-Andro on muscular strength. Participants in both groups didn’t differ in their back squat, bench press, or deadlift strengths at the study’s onset.

Results from the study indicate that the prohormone group may have potentially improved the bench press and deadlift strengths throughout the study, while those values remained unchanged in the placebo group. Thus, the prohormone group exhibited significant gains.

1-Andro Vs 4-Andro

1-Andro and 4-Andro are both prohormones. That means that the body could potentially convert these chemicals into hormones such as testosterone. Andro is legal at the time of writing because it is allegedly found in the bark of some trees and hasn’t been proven to act as an anabolic compound. [R]

Here are the major differences between 1-Andro and 4-Andro:

• 4-Andro directly converts to testosterone. In contrast to 1-Andro, which is potentially changed by the body to 1-testosterone, 4-Andro may be directly converted to the muscle-building hormone, potentially raising natural hormone levels.
• 4-Andro experiences slight estrogen conversion. This is not the case with 1-Andro, which isn’t converted into estrogen or DHT. So, unlike anabolic compounds, a proper post-cycle research therapy (cycle support) to mitigate potential side effects won’t be needed.

1-Andro Side Effects

The same trial that established that 1-Andro could potentially help bring about muscle gains also highlighted this prohormone’s various side effects. In fact, the trial’s title contains the words that this prohormone ‘impairs user health’.

Researchers include a potential reduction in HDL cholesterol, an increase in LDL cholesterol, and detrimental changes in kidney and liver function among the study’s subjects.

Some of the side effects experienced by the study’s participants include a potential reduction in HDL cholesterol, an increase in LDL cholesterol, and detrimental changes in kidney and liver function.

Self-reported side effects may include acne, headaches, dehydration, muscle cramping, and mood swings. [R]
