Boldenone undecylenate is a highly anabolic and moderately androgenic steroid. It’s primary use is in veterinary medicine most commonly with horses, but has become a favorite of strength athletes and bodybuilders. There is very little aromatization related to the compound with a very limited amount of water retention experienced by most users. Another attractive quality of the compound is the ensuing increase in appetite often reported by users when running this steroid and will often be included in “bulking” cycles for this purpose. Boldenone undecylenate also increases hemaglobin and hematocrit (the number of red blood cells and the percentage of red blood cells)1 , thus causing greater “pumps” while working out. Although this is true of nearly all anabolic steroids the effects are reportedly more pronounced with boldenone undecylenate. An improvement in vascularity should also be experienced due these increases, if body fat is at a low enough level.

Athletes other than bodybuilders or those concerned primarily with strength may also benefit from boldenone undecylenate. This is due to the fact that the compound stimulates the release of erythropoietin, commonly referred to as EPO, in the kidneys. Erythropoeitin signals the body to increase the production of erythrocytes (red blood cells). Erythrocytes are the carrier of oxygen in the body and therefore if their concentration is increased in the body, a higher maximal oxygen capacity is produced and performance can be improved due to a delay in the on set of fatigue, including the build up of lactic acid. While the results would not be overly dramatic, a user should definitely notice an improvement all things being equal.


Due to the compounds active life, injections are usually conducted twice per week to maintain stable blood levels although some users prefer injecting only once per week. Most users anecdotally report that the minimum dose for most males is between 300mg to 400mg to see any substantial effects from the drug. Women of course will see results at much lower doses, usually ranging from 50-150mg per week for less experienced users.

Like most compounds, the majority of users prefer to stack boldenone undecylenate with testosterone. This should negate any libido uses that a user may encounter, as well as providing a potent combination that should result in a dramatic increase in lean body mass. Due to the lack of liver toxicity associated with the compound, other compounds that can raise liver values (such as 17 alpha alkylated steroids) can be run with boldenone undecylenate without any further complications.

Many users believe that boldenone undecylenate can be used both in “bulking” cycles and “cutting” cycles, as the lack of water retention associated with it’s use and improvement in vascularity while on the compound can help to show improvement in definition while a user is reducing his or her body fat. At the same time, the compound has a profound effect on lean body mass and the results can be dramatic when run with a diet high in protein and calories, along with a proper training regimen.

Not considered to be a rapid mass builder in comparison to other anabolic steroids, boldenone undecylenate will add quality lean muscle consistently throughout a cycle. Anecdotally, users have reported that cycles of at least ten to twelve weeks running boldenone undecylenate are needed to see the full effects of the compound.

Risks/Side Effects

For the most part, problems such as gynecomastia and a high degree of water/salt retention are nearly unheard of with this compound. Boldenone undecylenate’s rate of estrogen conversion is approximately fifty percent of that of testosterone. As well, since boldenone undecylenate is not hepatoxic to any serious degree it can be used for long periods of time during extensive cycles. Some side effects that may be experienced are acne and increased body-hair growth, as well as the usual virilizing effects in women, however these will likely be at a far reduced level than other compounds. If a user does not stack the compound with testosterone they may suffer sexual side effects, as is the case with the majority of anabolic steroids.

A user’s lipid profile will be negatively affected, as with any steroid, but not to the same degree as with a strong androgen. Boldenone undecylenate can convert to DHN (a very mild androgen in comparison to DHT) via 5- alpha reductase, however only a small amount will actually be converted meaning that the compound it is not hard on the hair line. However, like most other compounds if you are prone to male pattern baldness, boldenone undecylenate can speed or make the condition more pronounced. Prostate problems are also unlikely to be experienced.

The compound’s active life is 14-16 days, however boldenone undecylenate does produce detectable metabolites that will appear in a user’s urine for several months after administration of the drug has ceased. This makes the compound less than ideal if drug testing.


I used Equipoise last winter on my bulk. The cycle was 800mg Test E, 800mg Tren E, & 1200mg EQ (along with various orals). I did a 3600mg frontload of EQ and the cycle was 15 weeks long.

I felt the EQ helped offset some of the appetite suppression I get on Tren, and helped the bulk move along nicely instead of having to force myself to eat. I went from about ~205lbs to 230lbs without gaining much fat at all. Tren already makes me pretty vascular so it’s hard to say exactly how much the EQ helped, but it might have added a little bit.

I am not a guy that lets the thought of potential sides get in my head, but when people say they get anxiety on EQ, they are not lying that it is a potential side. I had never in my life experienced anxiety (and haven’t since), but I definitely experienced some on EQ and I feel bad for people that have to deal with that normally. I can’t remember exactly when it started… The only time I would experience it was right before I pinned and it would happened every time; thinking about Tren cough. And that’s it. It didn’t affect me in any way in my day to day life, just when I was about to pin.

Overall, I would potentially use it again, but there are plenty of other things to try before going back to EQ.


  • 500 test + 500 equipoise. 20 weeks.
  • Appetite boost.
  • No anxiety.
  • No boner issues.
  • Delts and traps got visibly bigger.
  • VEINZ. Arms got MUCH MUCH more veiner. They are visible even at high fat percent ( ~15% ) and not pumped.
  • Effects persisted at 60-70%, when i hopped off.
  • Noticable endurance boost.
  • No noticeable strength boost.
  • Had to use less AI, anecdotally equipoise somehow made my estro from test lower.

Cons: Hematocrit was 53 after the cycle, it took about 5 months and about 5 blood donations to get it to norm on cruise No other compound had such an impact on my hematocrit. Currently i am on 250 test + 100 deca and do not have to donate blood. Even on 500 test + 500 mast + 500 tren i did not have such hematocrit boost.


My experience with boldenone (cyp ester) was nothing short of amazing. For me it was a very mild drug, but something I’ll most likely run again. I first ran it at 600 mg but later bumped it up to 900 mg. What I noticed first was the increased hunger, and how I would seemingly become hungry much faster after a big meal. Normally I’ll eat every 3½-4 hours, but I could eat a big meal (around 12-1400 calories clean) and I’d feel that weird hunger lurking in my stomach not much later than 2 hours. Funny thing is I could easily push it aside and just wait for my planned meal – the hunger would sort of come in waves.

I became extremely vascular on it, though mostly my forearms which already are vascular to a great degree. The reason as to why I didn’t experience the same kind of vascularity on the rest of my body could be due to my fat percentage, which was around 14-15 percent (conservatively estimated – perhaps it was a tad lower). I did not experience bouldershoulders, at least not to the degree I see on this sub. They did grow a good amount, but nothing out of the ordinary in regards to other bodyparts. My cardio went through the fucking roof. I live in a european capital, and thus I transport myself on bicycle all the time. I was stunned how little out of breath I became, and this was extremely pleasing to me, perhaps because it really enhanced my idea of my body being a fucking machine (in sharp contrast to the image of the “lethargic beast in the sofa, that only really shines when he lifts weights”). Whats perhaps even more significant about this attribute is having hot, steaming sex. I do roids for self-improvement, and one of the benefits of self-improvement is bitches. I love to fuck, and I always fuck a girl like its my last day on earth; being able to fuck her senseless without having to take breaks really enhances the whole alpha-motherfucker-image. On a sidenote I also noticed I could get away with shorter pauses between sets while in the gym, effectively cutting down overall trainingtime (increased density), which is great.

For info I ran it for 18 weeks. Gains were dry and slow, but I was very pleased with the look.

The cycle was 300mg Test E, 600 Eq for 20 weeks and with frontload. Benefits: I never felt the eq “kick in” however this is what i noticed: Week 3 my hunger increased significantly but seemed to normalize the rest of my cycle. However I felt like I could eat more without feeling super stuffed. I train for powerlifting. I was able to handle a lot higher volume with more weight because recovery on Eq was a lot better compared to just Test alone. I got somewhat more vascular but not a lot. Maybe 12-14% bodyfat is still too fat to see much of a difference. Delts started to pop around week 8-9, this could also be due to more focus on accessories and higher overall volume. Previously I focused almost entirely on Bench, Squat, Deadlift. Overall I made good progress on all lifts, gained some muscle and leaned out quite a bit. I was eating at a surplus, but for some reason Eq made me stay relatively lean.

Sides: I’m a dude that sweats a lot. My first cycle increased sweating a bit. Eq was fucking annoying. I felt like I was constantly sweating. A lot. I would take a shower in the morning, put on a shirt go to uni and the shirt was drenched in sweat. It’s not even that hot where I’m from. I got that bronze tan everyone talks about. Got comments on the regular, how I am so tanned. We don’t get a lot of sun here:( Sex drive decreased on Eq, but I had 0 ED. I’m 100x hornier on just a cruise. Bp went up quite a bit, same as resting pulse. Donating blood halfway through cycle did not help the bp too much, but I no longer got headaches. On cycle I did not realize mental side effects of the Eq. However once off cycle looking back, I was feeling off quite a few times. I’m usually very laid back but on Eq I felt a lot more stressed out about stupid stuff that usually does not bother me at all. Pinning is something I look forward too, however on eq I was always freaking out for no reason. Also some other stuff, but that would be too long to explain. I would and will run Eq again, but this time I wanna try a shorter ester and in combination with tren. Besides the side effects, I really like the progress I was making and the way my body transformed.

I like it, was running it for last 6 weeks @ 500-750mg week with some npp and var.
Now that I have a full batch, front loading it 2500mg for 2 weeks, then 1000mg and 400mg npp w. 40mg to 60mg day of var. great morning wood and a 25-35% increase in cardio. great pumps. Currently on a keto cut slash slow clean bulk. (yes I know too much product for a cut but have a ton of 19-nor product that I need to get rid of to transition to a test or eq cruise/blast for next year).

Super stressful in job right now, high stakes and no/zero anxiety everyone complains about. Full disclosure- Aniracetam 750mg, Noopept 12mg, Sulbutiamine 250mg in morning last 2 weeks.

My theory on the prevalent anxiety issue could be that it it is low blood sugar… so when in keto no anxiety. But did a cheat week and still no anxiety, and still super stressful- so maybe it could also be a case of a bunch of internet bitches that are blaming their psychological issues on this product.
I think EQ is great< I may even replace this with test E for a cruise. don’t mind giving blood, like it that i don’t have juggle anti-prolactin issues like w. 1200mg+ of 19-nor products.

Front loaded with 2g, now I’m running 750mg ew along with 1500 test, 525 tren (soon to be increased) and starting 100mg Anadrol Ed next week. Would you guys bump the eq or should 750 be sufficient?
My appetite has been terrible lately though. I haven’t run any orals in quite a while, but I feel like when I’m on 30mg Superdrol. I have to force myself to eat, and it’s really hard to get clean calories down. I’m hoping this is just because I’ve been out of the gym for a few weeks due to an injury, and once I get back in the gym my appetite will increase.

Ran EQ twice now, once on a bulk with test e and tbol, another on a cut with test p, tren a, mast p, and winny. Both times my anxiety increased, and I didn’t feel it was that great as a bulking agent. Prefer something like test deca dbol to bulk. On the cut, I’m not sure if it increased vascularity or not because I got pretty lean anyway. My experience with it has been pretty underwhelming.

Frontloaded and ran 1500mg with 500mg test e for about 15 weeks (I would recommend longer but the frontload helped).

No noticeable sides other than needing more AI and hunger. Anxiety not noticeable for me personally but if you are prone to it I would suggest adding more test.
Big veins, big endurance but no auto strength increase (strength was gained since I added volume), looked a lot better in the mirror and lifts went up.

For me personally I recommend it because it is not such an extreme drug, low/no sides for decent gains. You can easily run it for a long time and throw some orals in along the way. I personally feel that the people who didn’t like it get unlucky with anxiety or they run it at a too low dose.

Bang for buck I am sure tren wins every time but then you have the sides to deal with.

I would definitely run again for a bulking cycle I think the endurance and hunger would really help.

Advice would be to brew it at no less than 500mg/ml, run it for 20 weeks ideally, frontload frontload frontload, stock up on food, keep it simple with just test and some orals (this will help keep a check on anxiety side effect if you are prone to it).

Ran posh Eq up to a gram a week with test, tren and Mast . Didn’t really notice a lot of cosmetic differences. My appetite didn’t noticeably increase. I also started incorporating a lot of circuits and a bit of extra cardio to see if it would boost my cardio but I didn’t notice too much of an increase. I usually take notice of a compound when I come off of it but once Eq cleared, I didn’t notice much loss of any unique attributes.

All in all, it was a pretty mild compound with minimal sides. I would use again more primarily for overall growth with minimal sides.

Just now finishing up 375/750/900mg Test E/Tren E/EQ. No bad sides from the EQ other than increased hunger starting week 2 (I frontloaded with a tri-bold blend) & tapering off by week 16 or so. I would not run EQ on a cut ever! It’s a great dry, lean bulker especially if you have appetite issues but it is very mild overall. Starting around week 14 I began getting 24×7 calf & forearm pumps/cramps that feel just like the ones I get on tbol. Other than the increased hunger, I feel that is a good compound to liken it too: injectable, long-lasting, slow-acting tbol. Don’t think I’ll ever get around to running it again. Going to try DHB next bulk & then Trest A the bulk after that.
