Euro-Pharmacies Testosterone Base 10 ml vial (50 mg/ml)

Testosterone Suspension

For those unfamiliar, Testosterone does not have a specific form known as a “testosterone suspension.” Due to its large molecular structure, testosterone is largely insoluble in water. Hence, pharmaceuticals typically dissolve this steroid in various oils for injectable formulations.

Altering the steroid’s lipid solubility involves adding specific compounds to modify absorption rates and extend the action duration. Common formulations include various side chains such as propionate, acetate, decanoate, and more, when mixed in sesame oil, they form a suspension.

To enhance testosterone’s oil solubility, esterification is employed, which consequently delays testosterone’s release into the bloodstream post-injection. Notably, testosterone cannot be administered orally and is solely for intramuscular injection, where it is gradually absorbed.

Different suspensions exhibit varied absorption speeds, yet all can be injected less frequently than daily, often lasting in muscle depots for days to a week. Tesamone represents a standard oily testosterone suspension, sharing efficacy with other testosterone products—it acts both as an anabolic and androgenic agent. Numerous testosterone suspensions are available in the USA, requiring a physician’s prescription.

Therapeutically, testosterone suspensions address conditions linked to testosterone deficiency or gonadotropin release issues. Testosterone is prescribed for:

• infertility
• delayed puberty
• advanced breast cancer in women
• growth promotion in malnourished individuals

Pharmacology

Responsible for normal male sexual organ development, testosterone maintains secondary sexual characteristics, influencing the prostate, testis, seminal vesicles, penis, and scrotum growth as well as overall body development. Although primarily an androgenic hormone, it displays significant anabolic properties, promoting protein synthesis and enhancing nitrogen balance when paired with a high-calorie diet.

Additionally, testosterone mildly boosts red blood cell production by stimulating EPO synthesis in the kidneys, thereby enhancing oxygen-carrying capacity.

Prolonged use of testosterone can inhibit gonadotropin release from the pituitary gland through a negative feedback loop and might also suppress spermatogenesis at elevated doses.

Dosage

Administered exclusively through intramuscular injections, testosterone suspensions retain efficacy for 48-72 hours, remaining detectable in urine for a significant duration. Esterification prolongs testosterone activity, although users often report discomfort from buttock injections, possibly due to high volumes or abscess formation. To mitigate this pain, low-volume doses and site rotation are advisable.

A novice bodybuilder’s recommended starting dose is approximately 25 mg weekly, with some individuals opting for 50-100mg. Others may employ cocktail combinations of different testosterone formulations. Treatment periods should remain 4-6 weeks to allow the hypothalamic-pituitary axis and testes to recuperate.

During the washout phase, athletes often take Nolvadex (tamoxifen) to counter estrogenic side effects.

All vials must be inspected pre-injection; any persistent fine crystals after shaking signal that the vial is unsuitable. As with all testosterone products, suspensions inhibit testosterone synthesis in the testes and affect the hypothalamic-pituitary axis, necessitating a gradual taper-off rather than abrupt cessation.

Duration

The treatment course for testosterone suspensions varies based on age, sex, diagnosis, treatment response, and side effects onset. Always inject testosterone into the buttock muscles and not subcutaneously, rotating the injection site to prevent abscesses. Alternatively, injections may occur on the outer thigh and should never be administered intravenously.

The dosage of testosterone suspensions should not exceed 200-1000 mg monthly due to potential side effects. Inspect the product before injecting; it should appear colorless-yellow and clear—any particulates suggest expiration or inactivity. Treatment duration typically spans 1-2 months, with storage at room temperature.

Bodybuilders

Many bodybuilders utilize testosterone suspensions predominantly in the off-season, as the drug’s presence in the body extends considerably. Its use during active competition is discouraged. While testosterone displays anabolic and androgenic properties, its effects are not instant, requiring around 3-4 weeks to manifest. Bodybuilders often combine it with other anabolic hormones like GH/thyroxin. Given that testosterone converts to estrogen in fatty tissues, some users experience breast enlargement and water retention. Typical dosages aimed at muscle mass and strength gains range from 250-1000 mg weekly. However, higher doses entail serious side effects, making lower starting doses advisable for beginners.

Protein mass increases gradually, alongside enhanced red blood cell production, aiding performance in intense exercise. Preferred by many, the type of testosterone suspension varies based on source availability. The drug claims to promote health, enhance exercise capacity, and support a positive nitrogen balance, though water retention is sometimes substantial, prompting some to use diuretics.

To mitigate breast enlargement, testosterone cycles with Arimidex or Tamoxifen. Users typically cycle for 4-6 weeks before pausing for several weeks, potentially using Arimidex during this washout phase.

Side effects:

• irregular menstrual cycles
• virilizing effects
• deepening voice
• clitoral enlargement
• gynecomastia
• painful penile erections
• hair loss, acne, oily skin
• water retention
• nausea, vomiting, jaundice
• rare liver cancer
• mental changes—anger, depression, anxiety
• elevated serum cholesterol

While most side effects are reversible, breast enlargement and specific virilizing effects can be permanent, with concomitant estrogen use sometimes failing to alleviate virilization symptoms.

Women

All testosterone analogs carry the risk of virilizing effects upon prolonged use. In women, symptoms may include deepening voice, excessive hair growth, irregular cycles, mood shifts, and clitoral enlargement. Immediate cessation at the first sign of virilization is recommended, as some effects may not reverse post-discontinuation.

Warnings

Exercise caution when using testosterone in individuals with:

• breast cancer and hypercalcemia
• liver dysfunction
• cardiovascular issues

Reports of dry cough or breathing difficulties post-injection have occurred, potentially linked to the oil-based formulation or contaminants.

Regular monitoring of liver enzymes and blood hematocrit is advisable for all testosterone users to ensure normal limits.

Overdose

Overdosing on Tesamone is uncommon. Despite potential large doses, acute life-threatening effects are usually absent. However, users may feel adverse effects for weeks as the drug clears, making an ER visit advisable.

Follow-up consultations with healthcare providers are crucial for anyone using anabolic steroids to ensure liver enzymes and hematocrit remain within normal ranges.

Legal

Testosterone is classified as a Schedule III controlled substance, obtainable only with a doctor’s prescription. However, many physicians hesitate to prescribe steroids.

Detection

Testosterone suspensions persist in the body for a considerable duration. Current detection methods can identify testosterone or its metabolites in urine for at least 3-4 weeks after cessation. Advanced testing methods can even detect traces in hair 2-4 months post-use.

Nevertheless, testing methods for testosterone suspensions have limitations, with approximately 50% of users evading detection based on testosterone/epitestosterone ratios.

Cost

Legal testosterone suspensions are challenging to acquire; most bodybuilders resort to black market sources. Generic formulations from Europe and Mexico are widely accessible, with prices ranging from $10-$40 for a 250 mg vial. Increased regulation by the DEA over the past two decades has led to rampant counterfeit products—caution is strongly advised when purchasing.
