Nandrolone Laurate
Active Substance: Nandrolone Laurate
Description
Nandrolone Laurate, also known as nandrolone dodecanoate, is a synthetic anabolic-androgenic steroid (AAS) and an ester of nandrolone. It is primarily used in veterinary medicine, particularly in countries like Austria, France, the Netherlands, and Switzerland. Its chemical name is [(8R,9S,10R,13S,14S,17S)-13-methyl-3-oxo-2,6,7,8,9,10,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-17-yl] dodecanoate.
Nandrolone esters, including Nandrolone Laurate, are known for having a strong anabolic effect with relatively weak androgenic effects. This profile makes them a popular choice for performance enhancement and muscle building.
Benefits and Side Effects
Benefits:
-
Muscle Growth and Anabolism: Nandrolone is a powerful anabolic agent, meaning it promotes the growth of muscle tissue.
-
Appetite Stimulation: It can increase appetite, which is beneficial for individuals with muscle-wasting conditions.
-
Increased Red Blood Cell Production: Nandrolone can stimulate erythropoiesis, leading to an increase in red blood cell count. This can improve oxygen delivery to muscles.
-
Increased Bone Density: It has been shown to be effective in treating conditions like osteoporosis by increasing bone density.
-
Therapeutic Uses: Clinically, nandrolone esters have been used to treat conditions such as anemia, cachexia (muscle wasting from diseases like cancer and AIDS), and some types of breast cancer.
Side Effects:
-
Androgenic Side Effects: While less androgenic than testosterone, nandrolone can still cause masculinizing effects, especially in women. These can include acne, increased body and facial hair growth (hirsutism), a deeper voice, and clitoral enlargement. In men, it can lead to hair loss on the scalp and benign prostatic hyperplasia (enlargement of the prostate).
-
Cardiovascular Issues: High doses can lead to cardiovascular toxicity, including elevated cholesterol and triglyceride levels, and an increased risk of heart attacks and strokes.
-
Endocrine System Disruption: Nandrolone can suppress natural testosterone production, leading to hypogonadism and infertility in men.
-
Progestogenic and Prolactin Effects: Nandrolone is a potent progestogen and can bind to the progesterone receptor. This can lead to side effects such as gynecomastia (development of breast tissue in men) and, in some cases, symptoms related to elevated prolactin levels.
-
Liver Toxicity: While the lack of 17α-alkylation makes it less hepatotoxic than some oral steroids, liver problems are still a possibility, particularly with high doses.
-
Psychological Effects: Mood swings, anxiety, and aggression are also reported side effects of anabolic steroid use.
Pros and Cons
Pros:
-
Strong Anabolic Effects: Highly effective for promoting muscle growth and strength.
-
Lower Androgenic Effects: Compared to other steroids like testosterone, it has a more favorable anabolic-to-androgenic ratio, which may reduce certain side effects like scalp hair loss and prostate issues.
-
Therapeutic Benefits: Clinically useful for treating a range of medical conditions.
Cons:
-
Significant Side Effects: Despite a lower androgenic rating, it still carries a risk of serious side effects, including cardiovascular, endocrine, and psychological issues.
-
Progestogenic Activity: Its interaction with the progesterone receptor can lead to unwanted side effects like gynecomastia.
-
Legal Status: It is a controlled substance in many countries, and its non-medical use is illegal.
-
Long Detection Time: Due to its long half-life, it can be detected in drug tests for an extended period.
Dosage and Frequency
There are no widely accepted or medically prescribed dosages for Nandrolone Laurate for performance enhancement, as its use is primarily veterinary. However, based on information regarding other nandrolone esters like nandrolone decanoate (Deca-Durabolin), clinical dosages for humans range from 50 to 100 mg per month for some conditions, or 50 to 200 mg per week for others. In a performance-enhancing context, users often administer much higher doses, which significantly increases the risk of side effects.
Half-Life and Detection Time
Nandrolone esters have a long half-life. For Nandrolone Decanoate, the terminal half-life is reported to be between 7 and 12 days. The laurate ester is even longer, which means it stays in the system for an extended period. Detection times for nandrolone and its metabolites are notoriously long. For Nandrolone Decanoate, metabolites can be detected in urine for up to 18 months or even longer after the last injection, making it one of the most detectable anabolic steroids. Nandrolone Laurate would have a similar, if not longer, detection window due to the longer ester chain.
Progestogenic and Prolactin Effects
Nandrolone is unique among many anabolic steroids because it is also a potent progestogen. It binds to the progesterone receptor (PR) with significant affinity. This progestogenic activity is a key reason for some of its side effects.
-
Progestogenic Effects: The activation of the PR can lead to side effects such as gynecomastia, particularly when used with aromatizing steroids.
-
Prolactin Effects: The progestogenic activity of nandrolone can cause an increase in prolactin levels. Elevated prolactin can lead to issues like gynecomastia (especially a specific type known as "prolactin-induced gynecomastia"), sexual dysfunction, and reduced libido. Managing prolactin levels is a key concern for users of nandrolone.
Anabolic Androgenic Ratio
The anabolic androgenic ratio (AAR) is a measure of a steroid's ability to build muscle (anabolic) versus its ability to produce male characteristics (androgenic), relative to testosterone, which has a ratio of 1:1.
Nandrolone is well-known for its very favorable AAR. The ratio for nandrolone is approximately 10:1. This means it is considered to be 10 times more anabolic and only as androgenic as testosterone, which is why it's often favored for its "clean" gains and reduced risk of certain androgenic side effects. However, it's crucial to remember that this is a simplified ratio and does not account for all the complex biological effects of the drug.
