What Are Prohormones?
Before we do anything, let’s define prohormones. To put it in simple terms, a prohormone is an ingredient that, once in the body, is converted into an anabolic hormone. Prohormones are the closest legal “supplement” to anabolic steroids. They stimulate an effect that is milder but similar. We’re talking, of course, about muscle growth, strength gains and, depending on the specific product used, fat loss. (1)
What Does The Regulatory Landscape Look Like For 2026?
Prohormones have seemingly always been under scrutiny thanks to the fact they are seriously hardcore. There have been multiple bans over the years since their introduction in 1996.
Here in early 2026, the regulatory landscape for prohormones is still restrictive and strictly prohibited in competitive sports. Prohormones, which are precursors to anabolic agents, are heavily scrutinized by both the U.S. Food and Drug Administration (FDA) and the World Anti-Doping Agency (WADA).
Key aspects of the 2026 regulatory environment for prohormones include:
1. WADA Prohibited List (Effective Jan 1, 2026)
The 2026 WADA Prohibited List continues to ban all prohormones and similar compounds, placing them under S1: Anabolic Agents.
- Clarification: WADA explicitly clarifies that all esters of prohibited steroids are prohibited.
- Specific Prohibitions: The 2026 list specifically includes 2-Androstenol, 2-Androstenone, 3-Androstenol, 3-Androstenone, and Arimistane (Androsta-3,5-diene-7,17-dione).
- Strict Liability: Athletes are strictly liable for substances found in their body, including those stemming from contaminated, unlabelled, or misrepresented supplements.
2. FDA and Legal Status (U.S.)
The FDA continues to claim that prohormones are not legitimate dietary supplements, and many are considered unapproved, adulterated drugs.
- Enforcement Focus: It primarily comes down to how they are marketed. Supplement companies typically find loopholes that allow them to continue to be sold.
- Compound Contamination: The 2026 landscape shows continued, dangerous patterns of prohormones and similar compounds (such as SARMs or novel mitochondrial uncouplers like BAM15) being hidden in supplement formulas. That means that customers should research the company and purchase only from reputable companies that offer full product transparency and verifiable 3rd party testing.
- Testosterone Regulation: Testosterone itself is still a Schedule III controlled substance.
Regulatory Summary for 2026
Any supplement marketed as a “prohormone” is pretty much assured to be banned for competitive athletes. However, for all of those lifters that do not compete, and this includes competitive bodybuilding, prohormones are still available, but they are under constant threat of being yanked off the shelves.
What Are The Top 5 Prohormones For 2026?
Customers deciding to purchase prohormones need to fully understand what they are buying and how to use them. Customers should also be aware that the available market may change at a moment’s notice, as noted above. For those new to prohormones, see this article before you buy.
1). 1-Andro (1-Androsterone / 3b-hydroxy-5a-androst-1-en-17-one)
A very popular prohormone, 1-Andro goes through a two-step conversion in your body, converting from 1-Andro to 1-Testosterone. Since this is a non-methylated prohormone, it will not convert into DHT or estrogen, and liver toxicity is low.
What Is The Top 1-Andro Product?
Best For?
1-Andro is a good choice for lean mass and strength gains. It’s also a good choice for those lifters wanting to lose body fat.
Is PCT Required?
Yes, PCT and on-cycle support is recommended.
2). 4-Andro (4-Androsterone / 4-Androstene-3b-ol, 17-one)
4-Andro goes through a two-step conversion in the body and becomes testosterone. It is considered a “wet” prohormone. This means there’s a chance of estrogen conversion and excess water retention. While not ideal, that makes it a good choice for bulking. It’s also a good stacking choice, most commonly with 1-Andro.
What is The Top 4-Andro Product?
Best For?
4-Andro is a good choice for bulking cycles, and leads to mass and strength strength gains.
Is PCT Required?
Yes, PCT and on-cycle support is recommended.
3). 19-NorAndro (NorAndrostenediol/19-NorDehydroepiandrosterone)
19-Norandro is a precursor to the steroid nandrolone. It converts to nandrolone once it’s in your body and provides similar effects to the steroid Deca-Durabolin, a brand of nandrolone. This is another “wet” compound that adds mass quickly and has the side benefit of improving joint health.
What is The Top 19-NorAndro Product?
Best For?
19-NorAndro is ideal for mass and strength gains, as well as supporting joint health, allowing you to lift heavy. It’s also a popular stacking prohormone.
Is PCT Required?
PCT is recommended.
4). The Top Prohormone Blend For 2026
Blackstone Labs Metha-Quad Extreme – Here’s an Extreme formula from Blackstone Labs that features 4 well-dosed anabolic compounds in a single product.
Best For?
Blends can be catered to mass/strength gains or fat loss, depending on goals.
Is PCT Required?
PCT and on-cycle support is suggested.
5). 4-Androstenolone
Technically labeled a “testosterone aid”, this is a mild prohormone, yet strong enough to provide good results.
What Is The Top 4-Androstenolone Product?
Best For?
Andriol promotes mass, strength and is a good choice for fat loss.
Is PCT Required?
No PCT or cycling is required – you can stay on Andriol for as long as you want! Cool, right?
Honorable Mention – Hi-Tech Halodrol
Here’s a potent 250 mg per capsule blend consisting of 1-Andro and 4-Andro. This is one of the most popular prohormone formulas on the market. It’s too good to pass over, so it’s here as an Honorable Mention.

A Look At Post Cycle Therapy (PCT)
When you come to the end of your prohormone cycle (typically 8 weeks but it can run as long as 10-12 weeks), the body’s natural hormones are out of balance. What does this mean? Your natural production of testosterone is low and your natural production of estrogen and cortisol are high. This is why you end up losing some of the mass and strength gains you end your cycle with. This is also why your approach to PCT is critical.
You will need to control the fat gains and water retention caused by excess estrogen. In addition, you will need to get your testosterone levels back up to normal. Finally, you must get levels of the destructive catabolic hormone cortisol back in line. This approach allows you to keep most of your gains and is the reason you must run a PCT program immediately after your cycle.
Two points to be made is that you never keep all of the gains you end your cycle with, and you should continue to lift as heavy as possible even after your cycle is over. However, realize that you will lose some strength but if PCT is done right, you should be stronger than you were before you started your prohormone cycle.
