Boldenone has a relatively favorable side effect profile compared to most other anabolic steroids. Conversion to estrogen is low, and if anything the modest amount of conversion can be beneficial if no other aromatizing steroid is being used. Unlike testosterone, it’s not potentiated in the skin or scalp. Boldenone typically has little in the way of adverse effect on mood. The most common problems are increased appetite (in cases where that’s experienced as a problem) and at higher doses, sometimes a feverish feeling. But in general, it’s very well tolerated at modest dosages such as up to 400-500 mg/week and sometimes more.
With Boldenon in moderate doses aromatisation is usually not a problem to worry about. But it does aromatise a little so if you are sensitive or uses Boldenon in high doses there is still a reason to look out. This means that the risk of side effects like gynocomastia and water retention is small. The small aromatisation that does occur is positive for the glucose utilization (bringing back glycogen in the cell after a hard workout) and increases your natural growth hormone release. The main advantage is that oestrogen upgrades the androgen receptors giving an anabolic effect. Boldenon is not so toxic for the liver and the DHT conversion is also low. Acne and high blood pressure problems are also rare, this steroid is in all fairly safe to use and very much recommended.
