Prohormone Info

Here you will be able to find out what prohormones are, what each compound does, who should use prohormones, etc...

As you may have noticed Designer Anabolic Steroids (known as prohormones) that you once loved and became familiar with are now gone. H.R. 4771: Designer Anabolic Steroid Control Act of 2014 was enacted on Dec. 18, 2014. This bill classified 24 specific compounds as anabolic steroids. In addition, it also made it easy for anything similar in the future to be banned. The bill specifically excludes DHEA from the ban, which is why you will see Prohormones such as 1-Andro or 1-DHEA, 4-Andro or 4-DHEA, Epi-Andro and 19Nor-Andro or 19Nor-DHEA still on the market. These compounds are 100% legal and are safer to use. 

The Prohormones sold here at Black Diamond Supplements are still legal and extremely powerful if you know what you are looking for. If not, we will be glad to assist you in finding the right Prohormone to suit your goals.

What is a Prohormone? 

 A prohormone is a precursor of a target hormone. A prohormone is intended to be a precursor to an anabolic steroid and designed to convert into an active hormone once in the body. Prohormones, unlike anabolic steroids, do not add synthetic hormones to the body, but simply enhance/increase the availability of existing hormones/testosterone. Prohormones are typically used by athletes and bodybuilders to increase muscle size and strength, while reducing body fat. 

What is the difference between past Designer Anabolic Steroids and Prohormones?

 Prohormones occur naturally in the body and are a metabolite of DHEA (modified DHEA). They are not methylated, meaning they do not damage the body’s organs. However, some users still take Cycle Support Supplements to detox their body.

Do Designer Anabolic Steroids (previously known as Prohormones) have side effects?

 Yes. Like anabolic steorids, Designer Anabolic Steroids still carry many of the same side effects. Although minimal, side effects can include acne, hair loss, gyno (breast tissue enlargement), prostate swelling, etc... The risk of side effects can be reduced by taking precautionary measures like using Cycle Support Supplements. However, some people are predisposed to certain side effects, for example, if hair loss runs in the family you may be more likely to experience this side effect while taking prohormones, but side effects are usually temporary.

Do Prohormones have side effects? 

 No. Since the compounds are already naturally occurring in the body they do not cause side effects as Designer Anabolic Steroids did. However, side effects can still occur if a proper PCT is not used. These side effects can be acne, hair loss, gyno, lethargy, etc… Although these are very unlikely, everyone is different so proper use (cycling) is still very important. 

Who should use Prohormones?

 Prohormones should only be used by persons at least 21 years of age who have hit a plateau in their fitness goals for achieving the muscle size and strength they desire.

How often can I use Designer Anabolic Steroids? 

 Designer Anabolic Steroids should be ran in cycles of 4-6 weeks maximum. No matter how long or short your cycle is you should always use a Cycle Support Supplement and a Post Cycle Therapy Supplement. It is also recommended to use an Aromatase Inhibitor during the cycle. After running a cycle and completing your PCT you should always take a minimum of 4 weeks off. We recommend taking the same amount of time off as you are on (not including your PCT). For example, if you are on a prohormone for 6 weeks, you should take at least a 6 week break, after your PCT, before starting again. 

How often can I cycle Prohormones?

 Since Prohormones are not damaging to your body they can be ran longer or more often. However, we still do not recommend consistently taking them so your body does not become tolerant. It is recommended to only use in cycles of no more than 8 continuous weeks, but can be ran longer (at your own risk).

What is a Post Cycle Therapy (PCT) and do I really need it? 

 A PCT is the combination of a Testosterone Booster and Estrogen Blocker, used to help support your body's natural function after a cycle. A Post Cycle Therapy Supplement is definitely needed after running any prohormone cycle. When coming off a prohormone your body will start to produce more estrogen in order to bring down testosterone levels and balance out your hormone levels. Even though estrogen can be good, to much of it is bad. Estrogen increases can make your body store more water, creating the bloated/puffy look and can also cause gynecomastia (male breast tissue enlargement). Also, when coming of your prohormone cycle your testes are not producing as much testosterone, if any. This can cause lethargy and decreases in muscle size and hardness. With the use of a Post Cycle Therapy, you will help block estrogen and kickstart your body's natural testosterone production, giving you the ability to maintain more of your gains. 

Is a Post Cycle Therapy (PCT) needed after taking a Prohormone?

 Yes. It is still highly recommended and necessary to use a PCT following your cycle. A PCT will help your body restore its natural levels. If a PCT is not used, you are likely to lose most of your gains and may develop certain side effects due to a lack of natural testosterone production and an increase in estrogen.

What is the difference between a quad, triple and dual stack? 

 When a prohormone is referred to as a stack it usually means that it contains more than one compound. A quad stack would be any prohormone that contains four compounds, triple stack would contain three compounds and a dual stack would contain two compounds. Quad stacks and triple stacks we only recommend for experienced users, meaning you have used prohormones for years previous. For people who are new or just starting out, single compound or dual stack prohormones can yield just as good of results, but are less harmful to your body.

Do not be confused though, as stack can also reference a prohormone cycle. In this case a stack would include a prohormone (single, dual, triple or quad), plus everything else you need to properly cycle a prohormone. For example; on cycle support and post cycle therapy.


Prohormones: What really constitutes a prohormone vs a designer anabolic steroid? 

Target Hormone, this is what makes a Prohormone a Prohormone…it has to convert to an active hormone (aka Steroid). So this piece of information is crucial to understanding the effects of the Prohormone in question. If a Prohormone converts into Testosterone, it will give results similar to Testosterone. If it converts into another steroid, for example Nandrolone (Deca), it will give results similar to Deca.

Anabolic Potency: Indicates how powerful the hormone is for building muscle mass. The higher the number, the more potential for increased size and mass.

Androgenic Potency: Indicates how powerful the compound is for building strength, muscle hardening, and libido increases.

Cut or Bulk: How to best utilize the product - Should you use it when bulking up for size, would it be better when dieting down to get lean and hard, or can it be used effectively for both? 


1-Andro or 1-DHEA (also 1-androstene-3b-ol-17-one, 1-dehydroepiandrosterone or 3b-hydroxy-5a-androst-1-en-17-one)

Available Products: 1-AD, 1-Testosterone, 1-Andro, Anavar, Sustanon 250, Androbolic 250, Monster Plexx 

Target Hormone: 1-Testosterone 

Anabolic Potency: 200 (2x that of Testosterone) 

Androgenic Potency: 100 (1x that of Testosterone) 

Cut or Bulk: With 2x the anabolic potential of pure testosterone, this Prohormone makes an excellent choice for any bulking cycle. Users can experience significant lean muscle mass gains to the tune of 10lbs+ in just a month.


4-Andro or 4-DHEA (also 4-androstene-3b-ol-,17-one, 4-dehydroepiandrosterone, 4-androstene-3b-ol-17-one) 

Available Products: Anavar, Androdiol, Sustanon 250, Androbolic 250, 4-Andro, Monster Plexx

Target Hormone: Testosterone

Anabolic Potency: 100 (1x that of Testosterone)

Androgenic Potency: 100 (1x that of Testosterone) 

Cut or Bulk: As this compound converts into pure Testosterone, it means it is perfectly suited both for any bulking or cutting cycle. This compound makes a perfect “base” to be stacked with any other Prohormone available.


1,4-Andro or 1,4-DHEA (also 1,4-androstene-3b-ol-17-one, 1,4-dehydroepiandrosterone, 3b-Hydroxy-1,4-Androstadien-17-one) 

Available Products: Equibolin, Dianabol 

Target Hormone: Boldenone

Anabolic Potency: 50 (1/2 that of Testosterone)  

Androgenic Potency: 100 (1x that of Testosterone)

Cut or Bulk: Since it converts into Boldenone, a famous bodybuilding steroid which has a fortunate side effect of increasing hunger, this Prohormone is traditionally utilized on long bulk cycles. It offers slow and steady gains that can be used to solidify quick weight increases while bulking. For those with great self control however, this Prohormone can be used effectively on a cut as it directly increases vascularity and helps increase muscle hardness and definition.


19-NorAndro or 19-NorDHEA (also 19-NorAndrost-4-ene-3b-ol, 17-one, 19-Nordehydroepiandrosterone)

Available Products: Decabolin

Target Hormone: Nandrolone  

Anabolic Potency: 125 (1.25x that of Testosterone)

Androgenic Potency: 37 (.37 that of Testosterone)

Cut or Bulk: With an anabolic potential greater than that of Testosterone, Nandrolone (AKA Deca) is one of the most coveted bulking agents of all time.


Epiandrosterone or Epiandrostenolone (also 3b-hydroxy-etioallocholan-17-one)

Available Products: Anavar, Sustanon 250, Epi-Andro 50, Monster Plexx 

Target Hormone: Dihydrotestosterone 

Anabolic Potency: 260

Androgenic Potency: 60 

Cut or Bulk: This compound shows us that although the anabolic:androgenic ratio shows it SHOULD be a great bulking agent, the reality is that the body doesn’t always behave the way science says it should. This compound is actually the most effective hardening/strength/defining compound of all the Prohormones, and the weakest for mass gains. This is the absolute perfect option for any cutting cycle.


What is Cyclosome Technology?

The most advanced liposomal delivery technology ever developed for bioavailability and is the answer to getting poorly absorbed testosterone boosting compounds and legal prohormones into the body so they can work. The pharmaceutical industry has embraced this cutting-edge technology in recent years and now Hi-Tech Pharma and many other brands will utilize it in its prohormones and testosterone boosters.
