For something that is generally injected into cows, horses and dogs boldenone is quite a popular and well-liked drug by most bodybuilders because of its unique make-up. It possesses several characteristics that aren't found in any other substance and its use is so varied its much desired year-round. Boldenone is a decent anabolic coupled with both a mild androgenic and a mild estrogenic effect. Sort of like a weak testosterone. In structure it doesn't differ all that much from testosterone, the main anomaly being a double bond in the one position as well as the 4 position. Its nonetheless quite good at promoting gains, but mostly through a combination of androgenic potential and other media than the androgen and estrogen receptors.

The strange thing about its androgenic component is that it is mostly not mediated by a 5-alpha-reduced form, as is the case for most steroids. While it does indeed form a very potent 5AR form (dihydroboldenone, roughly 7 times as anabolic as testosterone1) its shows a very low affinity for the 5-alpha-reducatase enzyme2. This leads to the conclusion that a large part of the anabolic effect boldenone exerts is formed by the hormone itself binding to the androgen receptor. This could also be the reason its had such a successful run as a veterinary drug, because despite differences in the metabolism of species it has always produced extraordinary results.

Like most anabolic steroids it increases muscle mass over time by increasing nitrogen retention and positively influencing protein synthesis or re-synthesis. An action that is not necessarily supported by an androgenic mediator as was shown with nandrolone. What boldenone has that other steroids don't is that it indirectly supplies the necessary means for that protein synthesis because it drastically increases the appetite. Thereby facilitating the high nutritional intake (especially protein wise) needed to book the best results when using anabolic androgenic steroids. Its more of a benefit than you think as a lot of people have theorized that it is this increase that is responsible for the great results booked when using boldenone. This theory may hold its own as there is indeed not much proof of the kind of anabolic activity with boldenone that would be responsible for the elicited effect.

Its estrogenic activities are slight, but present. This has more of a positive than negative influence. The aromatisation of boldenone is too small to cause real problems and in normal doses (300-400 mg/week) problems such as gynocomastia and too much fat retention are unheard of. However small aromatisation is desirable as estrogen too mediates anabolic activity. It can be responsible for better glucose utilization3,4 (repleting lost glycogen stores after exercise) and stimulating increased growth hormone release5. But most notably estrogen is responsible for an upgrading of the androgen receptor6 allowing hormones that act on the androgen receptor to exert a larger anabolic effect. This is why hormones that are strong androgens but also aromatize heavily, like anadrol and testosterone, can put the most mass on your frame. In that aspect boldenone is perhaps the most suitable steroid because of its moderate estrogen levels that allow for the benefits, but not the side-effects of aromatization. And no doubt the perfect balance is partially responsible for stimulation of the appetite.

For athletes of sports other than strength sports or bodybuilding will also note that boldenone is quite likely the most favorable steroid for them to use as it also stimulates the release of erythropoeitin in the kidneys. Erythropoeitin is a hormone known as EPO and heavily abused among endurance athletes because it signals the body to increase the production of red blood cells (erythrocytes). Red blood cells are the carrier of oxygen in the body, meaning that a higher maximal oxygen capacity can be obtained and better performance can be achieved over longer amounts of time before lactic acid is built up, which would in turn result in cramps and a cessation of the activity at that level. In short it improves your stamina. For bodybuilders this characteristic may be useful in promoting increased vascularity.

In that aspect boldenone combined with a non-aromatizing steroid like Winstrol or Primobolan may be perfect to help you get cut and ripped while improving vascularity. The downside to that is that you really need to try hard to suppress the increased appetite. Which is why its probably a better idea to stack a somewhat larger dose of boldenone with a mass building drug like testosterone or anadrol to elicit major gains.

The negative effects of boldenone are quite limited. In the normal doses of 300-400 mg a week estrogenic side-effects are almost never noted except in those who are very succeptible to estrogen. In terms of androgenic side-effects long-term use or very intense use of boldenone can cause slight virilizing effects such as acne and increased body-hair growth. Never really a problem for men, but women considering its use on account of its moderate androgenic qualities should be aware of this.

As an undecylenate ester, boldenone needs only be injected every week (staying active well over 4 weeks), but because the preparations come in 25 mg/ml, users most often opt for 25-50 mg every day to every other day. A use of 300-400 mg per week seems to be the normal recommendation. Its not hepatoxic to any serious degree and can therefore be used for longer cycles. The appearance of underground forms of boldenone in higher concentrations (200 mg/ml) has made it easier to inject only once a week, which is to be preffered over the multiple dosings because it has a more even release and the cumulative effect shows much sooner. Speaking of cumulative effect, the best results with boldenone are seen when a user front-loads. Usually that means he will use a high doses of 600-800 mg/week for 2 weeks and then lower that dose to the normal 300-400 mg/week for the remaining 8-10 weeks.

Boldenone is most often used for cutting. Its stacking partners for this purpose in particular are trenbolone, stanazolol and testosterone propionate. I'm no big fan of testosterone for cutting, although propionate is commonly used with great success by many users. Nonetheless I don't recommend test for cutting for beginners. Stanazolol is particularly useful in improving muscle hardness and strength while boldenone offers increased vascularity without overly aromatizing. The use of 50 mg of stanazolol every day, stacked with 300-400 mg per week of boldenone should serve the purpose of retaining gains and gaining increased definition and vascularity while shedding fat very well. Trenbolone would be a better match for those looking for moderate but very lean gains. Parabolan at 76 mg every other day for example will provide a decent increase in lean mass in combination with boldenone, without having to sacrifice shape or definition. Of course any combination of the above is an option as well. For example 300 mg of equipoise per week stacked with 76 mg of parabolan every other day and 50 mg of Winstrol every day, possibly with some test propionate at 50 mg a day.

But though rarely mentioned, I personally find boldenone the better choice for bulking. Due to its effect on vascularity it is mostly used for cutting, but if you had a drug that increased your appetite like boldenone does, would you really use it to lose weight? It makes more sense to use it in a stack with a testosterone ester like enanthate or cypionate for good gains, instead of nandrolone. Sort of as a base. It aromatizes less than nandrolone and doesn't have that pesky progestagenic effect either, and because it increases appetite it would provide you with the means to an end in terms of gaining weight. 300-400 mg a week of boldenone with 500 mg of sustanon or 500 mg of testosterone enanthate would form an incredible stack. Even for those who prefer deca, adding a small amount of boldenone will go a long way in improving appetite. But boldenone is stronger than Deca, mg for mg, as well as safer and less suppressive.

Boldenone makes a very poor match for nandrolone and methenolone though, since its very similar in action. The beauty of boldenone is that it can be an alternative for nandrolone when bulking due to its leaner results and more potent anabolic action, as well as an alternative for methenolone because while barely aromatizing its stronger than methenolone (Primobolan), gram for gram. The use of secondary drugs is rarely required. It doesn't aromatize at a great rate so the use of anti-aromatases is rarely implemented and the use of Nolva and clomid, during a cycle, is only necessary when stacked with aromatizing steroids like testosterone. Nolvadex or Clomid may have some use in restoring natural test post-cycle, because of the long-acting ester (11 carbons) and the mild estrogenic component. Normally 4 weeks of treatment is required, starting 1.5 to 2 weeks after the last shot.



Equipoise was actually created while attempting to make a product which would be be a long acting injectable d-bol (Methandrostenolone). What was actually created was a product which, in the real world acts nothing like D-bol, despite it?s similarity to it chemically. A simple way to think of Equipoise, chemically at least, is simply as Dianabol without the 17-alpha-methyl group (that?s the thing which makes D-bol able to be ingested orally and not be destroyed by your liver). However, having had first hand experience with both Equipoise as well as D-bol, I can tell you that the results from each are vastly different.

To make Equipoise, a double bond was added between carbon atoms 1 and 2 of the Steran Nucleus of Testosterone. What does this mean? Well, first of all, since Equipoise was created by one simple modification in the testosterone molecule, you could rightly suspect that it shares many similarities with it. Equipoise is just as anabolic as testosterone (as you can tell by its anabolic rating above), but only half as androgenic. Those ratings can be quite deceiving though, as I don?t know anyone who would claim that you can gain as much weight on Equipoise as you can gain on an equal amount of testosterone (even though strength gains from the two compounds are very similar).

It?s not very common to compare Equipoise to testosterone; however& a far more common comparison is between Equipoise and Deca. I suspect this is because when Dan Duchaine introduced this compound to the steroid using community, he made an immediate comparison to Deca, speculating that it would act similarly to Deca but like a much stronger version of it. Equipoise doesn?t actually act much like deca at all; Deca is actually a progestin and a 19-nor derived steroid whereas Equipoise is more closely related to testosterone (being only one double bond differ rent). Duchaine later rescinded his original statement on Equipoise and said that it was disappointing as a mass builder when compared with deca, but a far better drug than for both strength gains and vascularity. Unfortunately, the myth that Equipoise?s action is similar to Deca?s has persisted for nearly 2 decades after he revised his opinion; this is most evident on internet message boards today, where many will advise against including both of them in a cycle because "they act the same way."

The 1-2 double bond that Equipoise has is responsible for many of its characteristics. First of all, it acts to slow aromatization (conversion into estrogen). The best estimate is that it does so at roughly half the rate of testosterone (1). This is the best number I?ve found in studies. Athletes almost never report estrogenic side effects with Equipoise, even when the dose is up to a gram per week. Side effects caused by estrogen include oily skin, acne, and gynocomastia, and as I said, those are usually not found from Equipoise. Virilization (development of male sexual characteristics in women) is almost never seen with this compound, when reasonable doses are used by female athletes. This is one of the few injectable compounds which could be successfully be used by female athletes and bodybuilders, and isn?t often faked.
Clinical Equipoise and Athletes

That double bond is also responsible for Equipoise?s resistance for being changed by the 5- 5-Alpha-reductase enzyme (2)(3). This enzyme converts a small amount of Boldenone into Dihydroboldenone, which is a very potent androgen (7x as anabolic as testosterone)(4). As I said though, such a small amount of it is converted that it?s really of no concern to most athletes taking Equipoise. This factor, plus its low aromatization rate mean athletes don?t need to consider using ancillaries with Equipoise.

Athletes taking Equipoise often report a slow and constant buildup of quality muscle, and certainly this has been my experience with the drug. I would speculate that this slow buildup of muscle is due to the very long ester attached to the Boldenone; Undeclynate is a longer ester than the decanoate ester by one carbon. Thus, we could expect the accumulation of muscle from Equipoise to actually occur at a slightly slower rate than that found with Deca (nandrolone decanoate). This leads me to advise that if you are considering the use of Equipoise, you should consider using it for no less than 12 weeks. Equipoise, like deca, is also detectable in your system for a long time (although it is substantially less than deca?s detection time).

Strangely, shorter estered versions of Boldenone are available as well. Anecdotally, many people (and manufacturers) claim that this produces less water retention...but water retention from Equipoise is virtually unheard of, so I consider this to be a silly idea.

An informal poll I took on Steroid.com (as well as with my friends) seems to put the ideal dose of Equipoise at 600mgs/week. Most people I asked about their Equipoise experience with Equipoise seemed to think that using over 600mgs/week produced no additional results, but the jump from 400mgs/week to 600mgs/week produced noticeable additional gains, and thus was warranted. I have personally found very nice results from 400mgs-600mgs/week myself.
Equipoise Side Effects

One of the most pronounced effects in Equipoise is its ability to raise your RBC?s (red blood cells). This is very typical of anabolic steroids; however, Equipoise would appear to do it to a slightly greater degree than most. One of the other effects most Equipoise users report is an increased appetite. I can say that this is true of me, also; this factor makes it impossible for me to diet on it. It?s because of this ability to increase appetite that many will include Equipoise in a mass cycle, and it?s for the quality of muscle gained on it that many will include it in a cutting cycle. It?s probably the most versatile injectable compound, next to testosterone. People even use a low dosed version of Equipoise to blend with irritating injectable drugs suck as testosterone suspension or Propionate. I?m thinking of the old Ganabol version which was dosed at 50mgs/ml, here... it?s not that Equipoise is especially good to cut other steroids with, but the low dose and cost of Ganabol made it ideal to do this with, when sterile oil wasn?t available or desirable. This low dosed version was also very popular with women, who were comfortable shooting 1cc of this stuff every few days or every week.

Equipoise will cause a suppression of your hormones, such as endogenous testosterone, so I would also recommend using injectable testosterone in any cycle containing it. Failure to do so could result in possible sexual dysfunction and other sides.
