Primobolan enanthate, also known as methenolone enanthate (Primobolan Depot) is a "sister" to the oral version, known as methenolone acetate.
They both rate the same in anabolic and androgenic potential.
The only difference is that Primobolan enanthate is an injectable version of the steroid.
Before choosing one form over another, know the difference between the two.
The injectable form tends to be more popular due to immediacy of benefits. Buy legal steroids online here.

Primobolan is the base drug.
The “acetate” or “enanthate” name attached to the drug is its ester (esterified) form.
Esters modify the absorption rate and half-life of a drug.
The acetate ester is known to be faster acting, but doesn’t last as long as the enanthate ester.
Anabolic androgenic steroids with longer-acting esters are preferred because injections don’t have to be given as frequently.
Generally speaking, the enanthate ester has a release time that lasts anywhere from eight to 10 days (on average,), while the acetate ester may only last two or three days.
A number of factors can influence the half-life and efficacy of any drug and include:
Methenolone enanthate (C27H42O3) otherwise is noted to provide not only benefits, but a number of rather serious potential for side effects and adverse reactions.
Methenolone enanthate may potentially act as a carcinogen. Women who are pregnant, expecting to become pregnant, or breast-feeding should entirely avoid the product, as it has the potential to cause fetal developmental damage.
It can also interfere with fertility. It is unknown how negatively anabolic androgenic steroids can affect breast milk. 
Like its sister (Primobolan acetate – oral), Primobolan enanthate is not known to be particularly strong in androgenic properties, reducing the potential for development of estrogen-like activity in the body.
This means reduced risk of gynecomastia, water retention, and bloating, but it doesn’t mean they’re not possible.
When it comes to Primobolan depot dosage recommendations, bodybuilders will find a variety of suggestions depending on personal preferences and results.
Every user may experience not only different results, but different side effects depending on dosage.
In medical situations, it was initially started at a 200 mg per week regimen, with maintenance dosages of 100 mg weekly, sometimes spread out into two-week increments.
Bodybuilders using a methenolone enanthate cycle often inject much higher than recommended dosages, averaging anywhere from 200 mg a week to 400 mg a week.
Experienced users tend to go even higher in regard to dosage, sometimes as high as 600 mg weekly.
Primobolan enanthate cycles can also vary, with some not taking it longer than six weeks, while others may take it for as long as three months or even more.
The higher the dosage and the longer the cycle, the increased risk of potentially undesired side effects.
Primobolan enanthate is often stacked with other steroids for accelerated results.
For example, in cutting phases, bodybuilders often stack it with the veterinary grade steroid, Trenbolone.
This combination can enhance viscosity.
Those wary of Trenbolone (rated as 500/500 in regard to its anabolic/androgenic potential) may prefer a gentler steroid such as stanozolol.
In bulking cycles, another form of testosterone is often combined with Primobolan enanthate to enhance the development of muscle mass.
Use of injectable steroids can reduce the risk of liver strain or damage due to liver toxicity, but even injectable steroids can put a strain on numerous body systems and activities.
While Primobolan enanthate is not known to be especially estrogenic, negative estrogen-like side effects can occur. However, the more common side effects associated with exogenous testosterone injections include:
Suppression of endogenous testosterone – this leads to testicular atrophy, decreased production of sperm, decreased sperm quality, and potential fertility.
Even after the drug is discontinued, it can often take months, sometimes as many as six or more, for natural testosterone levels to return.
Cardiovascular issues – high blood pressure and risk for atherosclerosis are also a potential risk that comes with anabolic androgenic steroid use.
Other serious side effects are also a possibility with use including but not limited to:
Some of the more serious side effects are associated with long-term use and high dosages, but every person will react differently.
Primobolan enanthate is not one of the most common anabolic androgenic steroids used anymore, due to the development of newer synthetic steroids, but it can still be found.
Before purchasing Primobolan enanthate online, perform due diligence and carefully research the seller, access forum board discussion threads to see how others have used the steroid, and always take into consideration the potential for negative reactions.
