Equipoise (Boldenone Undecylenate)

Boldenone undecylenate (Geneza Pharma)

Equipoise (boldenone undecylenate) is historically a veterinary steroid but for some time has been available as an UGL human preparation as well.

In the past, the principal reason for Equipoise’s use was it’s easy availability as a Mexican veterinary product. Presently, for the most part there is little specific reason to use Equipoise in an anabolic steroid cycle. There is nothing that it does anabolically that Masteron, Primobolan, Deca, or trenbolone will not do. In terms of side effects, likewise it has no advantage over Masteron or Primobolan, unless one desires the occasional side effect of increased appetite, or the side effect of its moderate conversion to estrogen. This can be useful if no other aromatizing steroid is being used.

Effectiveness of Equipoise

This is not intended to disparage the compound: it certainly can be put to good use in a steroid cycle. Its potency (effect per milligram) is comparable to most other injectable steroids, though less than that of trenbolone, and so for example addition of 400 mg/week is a substantial boost to most cycles. Alternately, if substituting boldenone for another injectable this can be done on a milligram-for-milligram basis.

Half-Life of Equipoise

A serious drawback of Equipoise is its long half-life, which is probably at least 12 days. This results in an extended period of time after the last injection during which levels are neither sufficiently high for optimal anabolism, nor low enough to allow recovery to occur. A solution for this problem is to use Equipoise in only the earlier part of a cycle.

Frontloading Equipoise

Another effect of the long half-life is that to achieve reasonably prompt effect, a large frontload is needed. I recommend that the first injection be an amount equal to 1.7 – 1.8 times the amount that will be used per week, plus the amount of the usual injection. So if for example the ongoing dosing will be 200 mg twice per week, on the first day the frontload should be about 900 mg.

Most do not do this, and as a result they experience little effect from Equipoise until many weeks into the cycle. For this reason, it’s widely claimed that Equipoise cycles need to be long or otherwise they do not work, but this really is not so. Instead the problem is failure to frontload, or failure to fronload sufficiently.

Another solution is to use the propionate ester, which now has some limited availability in powder form.

Equipoise Side Effects

Boldenone is metabolized by aromatase to estradiol, but to a lesser a degree than testosterone. It also is metabolized by the 5-AR enzyme, in this case to 17b-hydroxyandrost-1-ene-3-one, commonly but incorrectly called “1-testosterone” and sometimes called dihydroboldenone. This molecule’s potency is similar to that of boldenone, so the molecule is neither potentiated or deactivated by the 5-AR enzyme and therefore that metabolism is unimportant.

Stacking Equipoise with Other Steroids

Boldenone might be used in a couple of interesting ways, for example in combination with trenbolone to allow a lower dose of trenbolone while retaining similar anabolic effect and providing a needed amount of aromatizing steroid. It might also combined with Masteron or Primobolan, instead of testosterone, in self-prescribed HRT. The advantage would be reduced production of DHT. However, these uses have yet to be much explored.

But in general, for most Equipoise is not a first-call anabolic steroid. Not for reason of any real lacks, but simply because there are other choices that generally will work as well for the overall cycle plan.

Bill entered the nutritional supplement industry prior to completing his doctoral thesis but his education was invaluable so far as being able to design/improve nutritional supplement compounds, since it was in the field of designing drug molecules and secondarily some work in transdermal delivery.

His education was not specifically "geared" toward anabolic steroids other than expertise with pharmacological principles having broad applications. This has allowed Bill to provide unique insight into the field of anabolic pharmacology with knowledge of points which he would not have known otherwise.

did i read that right? Combining EQ and Mast can reduce DHT?

I’ll take a stab at that... Something like 10% of testosterone is converted to DHT. By using EQ *rather* than exogenous Test (at supraphysical levels) you would expect to see less T converted to DHT.

Always good info. Do you plan to provide other AAS spotlights in the future? Thanks

Equipoise does not directly reduce DHT. Neither does Masteron. They indirectly reduce DHT proportionate with the degree to which they suppress the endogenous or natural production of testosterone.

Equipoise is only weakly potentiated by the 5α-reductase and much less so than testosterone. Masteron is not converted to DHT at all.

The net result of an Equipoise+Masteron stack is lower DHT levels.

However, this is only true if you don't include any other AAS that are converted to DHT.

I don't understand what the advantage of reduced production of DHT would be, exactly.

The idea is that reducing DHT will help with skin/hair loss problems.

But as you probably know, reducing DHT too much can result in serious problems too.

For one , there is the role of DHT in libido / sexual function.

Also, DHT offers some antagonism to estrogen.

People want to find that Goldilocks balance -- not too high, not too low, but just right! :D

It did not make sense to me mostly because suggesting to lower DHT by administration of (also) drostanolone keeps the same receptors occupied - therefore maintaining status quo or worse.

In which case the good old medical practice - less is better would apply.

Cool drug.
Good for once per week injection due to the half life. Ideal for hiding your drug use,if you are that type.

Much conflicting information regarding its acting as an AI.

Volume of oil is an issue when buying ugl EQ.
Usually sold as 200mg/ml.
Recently I've seen some UGLs selling it at 300-400-500mg/ml.

It is liquid in room temperature but thick.

It is a ridiculously cheap raw in general.

Can be brewed at 650mg/ml.
It has no pip at 650mg/ml.
Confirmed by many people,me too.
This is due to the fact that it's already liquid in room temperature.

Theoretically you could pin it raw after filtering with a 18g needle. It is thick.

650mg/ml requires a 25g needle at best.
23g needle is ideal.

20%BB
2% BA
Rest is carrier. The thinner the better for this one. EO is what I use for everything, but particularily for EQ, I highly suggest it.

It raises RBC/HCT. Might need to donate blood.
Or therapeutic phlebotomy.
Frequency is relevant. This is definitely a drug that needs to be monitored with bloodwork to determine when and if you need to draw blood.

I hear it has a little to no effect on hairline,for most people.

I have heard some stuff about anxiety too. I had no issue.
Therefore E2 should be monitored also,as this could be the cause.

Some people need to dose it high. I have heard of stupid dosages. Some people do fine with low dosages as well.

I've gathered that it's sort of safe for the prostate. Take this with a grain of salt.

Dosages range from 400mg per week to "ridiculous". I won't mention what I've heard regarding what the upper range is.

Generally a mild drug with an effect on kidneys due to erythropoiesis. May be mild...or not.

Takes time to saturate due to the half life.
Some people frontload.

I have heard people running it from 12 to 20 weeks.

The only thing is that boldenone converts to e1 not e2 which is more active and potent. This I think limits its abilities because you have to run high doses for good anabolic effects so its ability to stack is limited. On the other hand, it has good strength gains and equal or superior connective tissue positive effects to deca and low water retention. I probably wont use it anymore because I did get anxiety effects from it and i used bold cyp which im pretty sure is fake sometimes and the undec ester is too long imo. It does have a mild effect as a AI. I am a low aromatizer and my levels were at a all time low with bold and have never been that low again with other compounds. I do not use AIs. Besides I really love nandrolone now because it made me feel euphoric at times and super horny. And it does convert to a form of e2 which is great because I aromatize low and benifit from the extra e2 kick. I did really like how bold didnt cause a ton of hypertrophy because i dont train hypertrophy much.

Good post

One of the few compounds I've never run and dont see myself running in the future.

I prefer shorter blasts and the shorter runs wouldnt really do justice to the slow and clea. gsins of EQ.

I also get minor BP issues, so I dont have to watch for HCT/RBC for my entire blast either.

Its a great compound that definitely has it's time and place, just not for me personally.

I have run my share of EQ over the years. Good for clean steady gains on a long cycle. Oil volume required gets tiresome but you can use high concentration product these days to lessen the injection volume. Overall I prefer other compounds over EQ. Deca, NPP or Primo get the job done more efficiently for me.
EQ did increase appetite and muscle quality but the cycle length and required volume get to be too much after a while.

@Millard - I really like these compound spotlights, keep doing them! It's cool to see some of the older articles too... Although, I'll admit, I was always a little iffy on some of Bill's cycling ideas.

I was on a private board years ago that had threads dedicated to different compounds and people would use them for general questions... Kind of similar to the DNP thread we have here. I think they were all stickied as "(compound XX) experiences thread", I think these spotlights might do well to be stickied too. I think it would help traffic on the board with content like that, give some new guys an easy way to learn about compound experiences and ask questions without having to figure out posting a thread and such.

It would be cool if I could get @Bill Roberts to join us for a few days to expound on it himself.

I think the rationale makes sense if you consider that he was speculating about potential AAS combinations in the context of HRT:

"[Equipoise] might also combined with Masteron or Primobolan, instead of testosterone, in self-prescribed HRT"

So, for example, the DHT levels of the following would be lower than 100mg test e per week:

100mg EQ
50mg EQ + 50mg Masteron
50mg EQ + 50mg Primobolan

I don't think many people thought it was worth trying because, honestly, it's hard for most to go wrong with 100mg weekly test e or c for HRT.

More have used this info to experiment with non-testosterone based cycles.

I'm glad you like them. I will keep doing them :)

After the first 10 or so, I think setting up a dedicated subforum for them would provide a good resource for sharing/learning about user experiences with each compound

No one can say Bill Robert's doesnt think outside the box lol.
Hes had some solid advice.. and not so solid imp
But he does push the needle forward and I've adopted a few of his cycle plans for myself.
