1-testosterone cypionate or DHB better information


Ok so I did alot of research to come up with these results and I understand now after all the reading that I have done why everyone is so confused about this compound. It now also makes sense to me why it kinda just came out of nowhere all of a sudden.

The reason for this is because DHB,1-TEST CYP or whatever you want to call it is just simply.
1-testosterone !!!
That’s it simple for those of us who used pre or prohormones know about 1-testosterone most likely.
What has been done here is when
1-testosterone was banned as a dietary supplement the China raw manufacturers were still producing it so what happened then was that it was then sold to black market ugl labs.
The compound was then given multiple names that different people used for the product. I can only imagine that this was because they didn’t want it to be the same as the dietary supplement.
It is actually different now then the original dietary supplement. They added a cypionate ester to it so that it would be a better injectable product instead of being an oral product.
When they added the cypionate ester to the product now is where the confusion began.
The name was changed to 1-testosterone cypionate even though it has nothing to do with testosterone. Then because every one was comparing the compound to a type of testosterone they then added the name DHB so now you have 1 compound with 3 different names. All which shouldn’t be the name in my opinion. I feel like instead of calling it what it really is they tried to give it a “brand” name.
The actual compound is

It is not boldenone cypionate it is not the 5a reduction of primo as I thought. It is not anything but 1-dehydroandrostanolone.

I have included a good read that will explain more.

Product Name:1-testosterone cypionate , Dihydroboldenone


Molecular Formula:C19H28O2

Molecular Weight:288.42

Anabolic /Androgenic Ratio: 200/100

5a reduced form Structure

1-Testosterone is also known as dihydroboldenone and 1-dehydroandrostanolone ,it is the 5a reduced form of boldenone. 1-Testosterone was the first fully active steroid introduced to the dietary supplement market.

This lack of 5alpha reduction with the compound allows users to administer it without suffering the negative side effects associated with this chemical reaction but also eliminates the benefits as well. Boldenone is not the only steroid that shares similarities with dihydroboldenone. In fact dihydroboldenone is chemically identical to the drug methenolone except for the 1-methylation that is apart of methenolone . 1-methylation was of course added to methenolone to make it more available when taken orally and thus dihydroboldenone is not efficiently utilized when administered orally, although it was once sold over the counter in tablet and pill form. Some of these over the counter preparations of the drug were done utilizing a delivery system similar to Andriol , i.e. producing an oil-solubilized product with dihydroboldenone. This would still not be a relatively worthwhile system of delivery to use however if one wanted to maximize the potential of the compound. Intramuscular injection is by far the most efficient method of administration to use as with most anabolic steroids.

As mentioned above, dihydroboldenone is structurally similar to methenolone and boldenone and less so to testosterone despite the commonly used name for it, 1-testosterone. For this reason some female athletes may be inclined to use the drug as well. The potential for development of symptoms of virilization still remain but are not as severe as with synthetic testosterone or other harsher drugs. This is not to say however that dihydroboldenone is a mild drug. To simplify the explanation of exactly what the drug is, it is to boldenone as dihydrotestosterone (DHT) is to testosterone. This would explain why the effects of the drug, both positive and negative, are so dissimilar to those of boldenone. Like testosterone and dihydrotestosterone, a portion of the boldenone that a user administers converts to dihydroboldenone. Also similarly, dihydroboldenone like dihydrotestosterone does not convert to anything else past that compound.

Favorable anabolic to androgenic Ratio

1-Testosterone has an anabolic to androgenic ratio of 200/100. With 1-testosterone, many users report a hardening effect and an increase in vascularity. 1-testosterone appears to be best used for size gains, although it should still provide the user with strength gains as well. In effect, 1-testosterone has been compared to Primobolan and Equipoise, though overall it is a much more potent compound mg for mg. 1-testosterone is considered a “dry” compound which can be used during cutting phases yet because of its strength is can also be useful during a bulking phase.

With its favorable anabolic to androgenic ratio, the low doses needed to see results, and the fact that 1-testosterone is already 5a reduced, androgenic side effects should not be too high with this compound in comparison to other steroids like testosterone. 1-testosterone cannot convert to estrogen, so the user should not experience bloating while on cycle and the risk of developing gynecomastia is low when 1-testosterone is used alone. One side effect commonly experienced by 1-testosterone users is lethargy. The exact reason for this lethargy is unknown, but it may be due to the fact that 1-testosterone lacks the energy and libido boosting effects of testosterone yet is still suppressive of natural testosterone production, or because of low estrogen levels. Stacking 1-testosterone with a more androgenic compound during a cut or a “wet” compound during a bulk does appear to relieve the issue of lethargy in most users.

1-Testosterone Cypionate

Indeed dihydroboldenone is available in numerous different esters. Cypionate , Ethyl Carbonate, Propyl Carbonate, and Propionate , among others, are all available for use with the drug. As always each does not offer any real advantages over one another other then the obvious differing active lives that each presents and the amount of time that it takes for the body to completely eliminate the drug from it . For the most part users will want to have their choice dictated by the injection frequency with which they want to deal with when using the compound, but of course they will also likely be limited by those that are made available to them.

Anecdotally some users have indicated that post-injection pain with dihydroboldenone can become an issue for some. Diluting the drug with either another injectable drug or some other type of sterile oil seems to alleviate at least some of this discomfort. The type of ester used does not appear to negate this pain for the users that experience it however.

1-Testosterone is still available on the black market as injectable 1-testosterone cypionate.While 1-testosterone and its direct prohormone 1-androstenediol are banned, 1-DHEA(1-androsterone) is still legally available and converts to 1-testosterone in a two step process.


Dihydroboldenone, while not overly androgenic, is a potent anabolic. It has been demonstrated that the drug binds extremely well and selectively to the androgen receptor and stimulates androgen receptor transactivation of dependent reporter genes . This equates to a drug that possesses the ability to stimulate significant muscle growth while not producing androgenic side effects.Also it does not aromatize and therefore estrogenic side effects such as gynecomastia and water retention are not a concern for users. It has been shown to be by far more anabolic than such compounds as boldenone, nandrolone , and even testosterone itself. Obviously this is of great benefit to many athletes.


As for specific dosages used with this drug, the low end is primarily thought to be 300–400mg a week for male users. For females the usual rules apply with dihydroboldenone as they do with other drugs. Anywhere from 25–100mg per week would be a good starting point for the majority of female users who have little to moderate experience with anabolic drugs.

The frequency of dosing with dihydroboldenone depends on the ester used with the compound. Seemingly the most popular current ester to produce the drug with is cypionate. Typcially, males would use a dosage of 200–400mg Dihydroboldenone Cypionate a week.No matter what ester utilized however the same rules would apply as with any other drug in terms of the frequency of administration needed to maintain relatively stable blood levels of the compound.

Orally, 1-testosterone has a very short half-life and is not very bioavailable because it is not methylated to avoid breakdown by the liver. When 1-testosterone is administered as a transdermal (absorbed through the skin), bioavailability is increased but its short half-life is still an issue. 1-testosterone was also sold as an injectable as 1-testosterone cypionate, which greatly increased half-life to about 4–5 days, making this the most effective way to use 1-testosterone. When injected, only 100–200mg/week is needed for an effective cycle.

Risks/Side Effects

With the positive aspects of the lack of aromatization associated with dihydroboldenone also come the negative ones. Fortunately these are primarily limited to such symptoms as lethargy, malaise and possibly a reduction in sex drive. These are caused by a lower ratio of estrogen in comparison to androgens in the body. For the most part however this effect is relatively slight and can be avoided with the use of steroids that do aromatize in conjunction with dihydroboldenone and thus restore a better balance in terms of androgens versus estrogen.

It also appears that the administration of dihydroboldenone may result in an increase in liver weight . This effect occurred when administering the drug orally but should also be true of the drug when administered via intramuscular injection. There is no research to indicate this however.

Other common negative side effects associated with the use of anabolic/androgenic steroids are still relatively mild with the use of dihydroboldenone. Of course suppression of the natural testosterone production of users will occur like with all steroids, however other side effects such as an increase in blood pressure, acne and others are comparably mild and often times non-existent in users, at least as they are directly related to the administration of this drug.

In terms of side effects for women, at moderate to heavy doses symptoms of virilization are likely. These can include such symptoms as clitoral enlargement, body hair growth and deepening of the voice. At lower doses however these side effects should not be a concern for the majority of potential female users.

I hope that this can finally put this confusion around this compound to rest.


Well I guess that clears that up, but I’m still wondering about the boldenone cypionate? Because it has been brought up in relation to 1-test cyp, what is it? Is it just boldenone with cypionate ester? Or is bold cyp actually a different compound, or name than boldenone?


Yep that’s exactly it boldenone cypionate is boldenone base with a cypionate ester attached.


Great read! Thanks , cleared alot up for me!


It actually cleared up alot for me also. I was completely wrong about this compound in what I believed that it was. I actually now am even more interested in using it.


Exactly!! I’m really inclined to include this in my next blast coming up now that I know exactly what it is :joy::joy:


I also believe that the dosing that people are using is not necessarily needed. Through everything read and what I know about 1-testosterone I believe that 400mg a week is actually enough 600mg being on the high end. I have seen 800+mg logs and it has been said that over 600mg brings heavy lethargic feelings. Now that I know it is
1-testosterone I would recommend adding a androgenic compound to balance it out like proviron or even mast p. I don’t think that mast is necessary but an androgenic balance is a good idea if you’re going to run this compound.
Just my opinion not science or proven as I haven’t used it yet.

I should also add that I read around 15 different cycle logs across different forums where members describe the sweet spot being 400mg ran stacked and 600mg ran with just testosterone.
This information didn’t only come from people behind a keyboard. I got alot of the knowledge I gained last night from actual experienced users opinions.
I know also that @Gingerlifter has his log going which is going to be great for the community. Also @Fitraver has a logging offer for it also from @PharmaComStore. So soon enough we will have a great perspective from good members at ugmuscle.com


I dropped my Tren last week and started my DHB in it’s place so if anyone follows my log they’ll have a good idea of what it can offer. I also did a crap ton of research over the last 2 months about DHB and found basically the same results you did. I tried a number of times to explain it to people but they just weren’t understanding. The way you wrote your thread, explains it quite well and should clear up any questions people may have about it’s history and what it actually is.


This was already stated but thanks for clearing it up.


You have a very good point about balancing out the androgenic levels. What would you think if running 400 mg of 1-testosterone a week and 400 mast make out for leveling out androgen levels? I really think those 2 compounds stacked would create great synergy together. As I read in the post earlier that 1- testoterone has a hardening effect.


I think Mast would be a great addition to DHB. It also has hardening effects and can provide some nice endurance and vascularity. Not to mention I find that it’s one of those “feel good” compounds. I’d run Mast with just about anything though lol.


I love mast for the “well being” effect it gives me.


Dhb has greatly increased me strength to all time high especially in squat 545x6 and rack pulls 700x3. This compound is no joke i friggin love it!


I’m starting to feel DHB now that I’m back…no doubt.


Bro…this thread literally had me doing research for two days​:sob::sob::sob:. I’m looking at my manufacturers price lists and seeing all three names with different prices each. Had to reach out to my people and make sure I understood what was being offered. Thanks for the read, took me down the rabbit hole!


It was crazy


Here is a Question I cant find the answer too. Why is the PIP so bad!!!


Sorry bro, this is 100 percent untrue. Please show me any model of an eq Cypionate molecule, or anybody that produces them or any research that has been done into them. They simply don’t exicst, it has no purpose. And as simple as jamming an ester onto a molecule, why aren’t the chinese doing it? Moving ions and electrons around is a dance you cant just shove things onto it, and pull things oft the original compound.

There is no EQ Cypionate, people pushing EQ cyp are just pushing 1testcyp or DHB or whatever the fuck people are calling it these days. There are no shore ester bodenones There was a dream by a man nemed AGCL, a long gone master chemist from early in the game, well he come up with several novel esterified compoumds, such as Mast E, and maybe Tren E, but also EQ Prop. God what a horrid liggle injection. Stay clear, there is a reason short ester EQ is not real.


Sorry but you are completely wrong.
There is boldenone cypionate and I can show you its molecular structure and I can show you the other attached esters to boldenone that are available.

How can you say that its impossible to attach an ester to any compound.

Your right there is no eq cypionate there is boldenone cypionate.
EQ is just a brand name given to a product.

This is the actual compound 1-dehydroandrostanolone
It was originally a prohormone and like EQ was given a brand name of 1-testosterone.
They wanted to make it an injectable after its ban from the supplement industry.
This is where all this nonsense about dhb and 1testcyp comes from.

You have boldenone cypionate which is a true compound
You also have 1-dehydroandrostanolone
Which shouldn’t be called anything but that unfortunately it has been given multiple brand names such as Dhb and 1-testosterone and then when the cypionate ester was added for injection purposes 1-testosterone cypionate


Where your going wrong is calling it EQ cypionate there is no such thing because you don’t combine boldenone undeclenate with a cypionate ester you attach a cypionate ester to just boldenone and I have already posted the molecular structure of boldenone cypionate if you want I can post it again
