Triolandren — testosterone blend

Triolandren is an injectable testosterone preparation that contains a mixture of three different esters of testosterone. Each milliliter specifically contains 20 mg of testosterone propionate, 80 mg of testosterone valerianate, and 150 mg of testosterone undecylenate, for a total steroid concentration of 250 mg/mL. With its mix of fast- and long-acting esters, Triolandren is very much like Sustanon® 250 in design, intended to deliver testosterone slowly to a patient over a period of several weeks. In this case the slowest-releasing ester used is undecylenate, whereas Sustanon® uses decanoate. This would make Triolandren the longer-acting agent between the two, also with a softer initial peak of testosterone release. As a testosterone drug, Triolandren is capable of promoting rapids gains in muscle, size and strength.

Triolandren History

The Triolandren testosterone formulation was first described in the medical literature in 1957. It was marketed commercially by Ciba in 1965, and sold as a human prescription drug in various parts of Europe. It was used primarily to treat anemia, androgen deficiency in males, breast cancer in females, and excessive growth in adolescents. During the 1980's, Ciba began trimming their global steroid offerings in light of the new public interest towards sports doping. By the mid-1990's, the last of the Triolandren preparations were withdrawn from continental Europe. Key markets such as Switzerland, Sweden, and Norway, which once were very active in its supply, no longer carried the drug, and it soon began to fade from the memory of most athletes. In 1996, Sandoz and Ciba officially merged to form Novartis. Any remaining Triolandren products made by Ciba-Geigy in other parts of the world were subsequently produced under the Novartis label. Triolandren remains available on the Egyptian drug market, although it is not commonly an item of export.

How is Triolandren Supplied

Triolandren® from Novartis is available in select human pharmaceutical markets. The product contains 250 mg/mL of steroid; packaged in 1 mL ampules.

Structural Characteristics of Triolandren

Triolandren® contains a mixture of three testosterone compounds, which are modified with the addition of carboxylic acid esters (propionic, valerianic, and undecanoic acids) at the 17-beta hydroxyl group. Esterified forms of testosterone are less polar than free testosterone, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) testosterone. Esterified forms of testosterone are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid.

Triolandren Side Effects (Estrogenic)

Testosterone is readily aromatized in the body to estradiol (estrogen). The aromatase (estrogen synthetase) enzyme is responsible for this metabolism of testosterone. Elevated estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia. Testosterone is considered a moderately estrogenic steroid. An anti-estrogen such as clomiphene citrate or tamoxifen citrate may be necessary to prevent estrogenic side effects. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), which more efficiently controls estrogen by preventing its synthesis. Aromatase inhibitors can be quite expensive in comparison to anti-estrogens, however, and may also have negative effects on blood lipids.

Estrogenic side effects will occur in a dose-dependant manner, with higher doses (above normal therapeutic levels) of testosterone more likely to require the concurrent use of an anti-estrogen or aromatase inhibitor. Since water retention and loss of muscle definition are common with higher doses of testosterone, this drug is usually considered a poor choice for dieting or cutting phases of training. Its moderate estrogenicity makes it more ideal for bulking phases, where the added water retention will support raw strength and muscle size, and help foster a stronger anabolic environment.

Triolandren Side Effects (Androgenic)

Testosterone is the primary male androgen, responsible for maintaining secondary male sexual characteristics. Elevated levels of testosterone are likely to produce androgenic side effects including oily skin, acne, and body/facial hair growth. Men with a genetic predisposition for hair loss (androgenetic alopecia) may notice accelerated male pattern balding. Those concerned about hair loss may find a more comfortable option in nandrolone decanoate, which is a comparably less androgenic steroid. Women are warned of the potential virilizing effects of anabolic/androgenic steroids, especially with a strong androgen such as testosterone. These may include deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.

In androgen-responsive target tissues such as the skin, scalp, and prostate, the high relative androgenicity of testosterone is dependant on its reduction to dihydrotestosterone (DHT). The 5-alpha reductase enzyme is responsible for this metabolism of testosterone. The concurrent use of a 5-alpha reductase inhibitor such as finasteride or dutasteride will interfere with site-specific potentiation of testosterone action, lowering the tendency of testosterone drugs to produce androgenic side effects. It is important to remember that anabolic and androgenic effects are both mediated via the cytosolic androgen receptor. Complete separation of testosterone's anabolic and androgenic properties is hot possible, even with total 5-alpha reductase inhibition.

Triolandren Side Effects (Hepatotoxicity)

Testosterone does not have hepatotoxic effects; liver toxicity is unlikely. One study examined the potential for hepatotoxicity with high doses of testosterone by administering 400 mg of the hormone per day (2,800 mg per week) to a group of male subjects. The steroid was taken orally so that higher peak concentrations would be reached in hepatic tissues compared to intramuscular injections. The hormone was given daily for 20 days, and produced no significant changes in liver enzyme values including serum albumin, bilirubin, alanine-aminotransferase, and alkaline phosphatases.

Triolandren Side Effects (Cardiovascular)

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.

Testosterone tends to have a much less dramatic impact on cardiovascular risk factors than synthetic steroids. This is due in part to its openness to metabolism by the liver, which allows it to have less effect on the hepatic management of cholesterol. The aromatization of testosterone to estradiol also helps to mitigate the negative effects of androgens on serum lipids. In one study, 280 mg per week of testosterone ester (enanthate) had a slight but not statistically significant effect on HDL cholesterol after 12 weeks, but when taken with an aromatase inhibitor a strong (25%) decrease was seen. Studies using 300 mg of testosterone ester (enanthate) per week for 20 weeks without an aromatase inhibitor demonstrated only a 13% decrease in HDL cholesterol, while at 600 mg the reduction reached 21 %. The negative impact of aromatase inhibition should be taken into consideration before such a drug is added to testosterone therapy.

Due to the positive influence of estrogen on serum lipids, tamoxifen citrate or clomiphene citrate are preferred to aromatase inhibitors for those concerned with cardiovascular health, as they offer a partial estrogenic effect in the liver. This allows them to potentially improve lipid profiles and offset some of the negative effects of androgens. With doses of 600 mg or less per week, the impact on lipid profile tends to be noticeable but not dramatic, making an anti-estrogen (for cardioprotective purposes) perhaps unnecessary. Doses of 600 mg or less per week have also failed to produce statistically significant changes in LDL/VLDL cholesterol, triglycerides, apolipoprotein B/C-lll, C-reactive protein, and insulin sensitivity, all indicating a relatively weak impact on cardiovascular risk factors. When used in moderate doses, injectable testosterone esters are usually considered to be the safest of all anabolic/androgenic steroids.

To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.

Triolandren Side Effects (Testosterone Suppression)

All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Testosterone, is the primary male androgen, and offers strong negative feedback on endogenous testosterone production. Testosterone-based drugs will, likewise, have a strong effect on the hypothalamic regulation of natural steroid hormones. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.

Triolandren Administration (General)

Testosterone propionate is often regarded as a painful injection. This is due to the very short carbon chain of the propionic acid ester, which can be irritating to tissues at the site of injection. Many sensitive individuals choose to avoid this steroid, their bodies reacting with a pronounced soreness and low-grade fever that may last for a few days after each injection.

Triolandren Administration (Men)

Although active for longer periods, this drug is usually injected on a weekly basis for bodybuilding purposes. The dosage used per injection is typically 250-500 mg (1-2 ampules). Cycles are generally between 6 and 12 weeks in length. This level is sufficient to provide excellent gains in muscle size and strength. Testosterone drugs are ultimately very versatile, and can be combined with many other anabolic/androgenic steroids depending on the desired effect.

Triolandren Administration (Women)

This drug is not recommended for women for physique-or performance-enhancing purposes due to its strong androgenic nature, tendency to produce virilizing side effects, and very-slow acting characteristics (making blood levels difficult to control).

Triolandren Availability

Triolandren is not commonly found on the black market, due to limited supply. It appears to currently be available only in Egypt and Taiwan (under the Novartis label).
