Testosterone suspension is popular among some athletes and bodybuilders for its high potency and rapid onset of action, yet it is less favored than the most commonly used testosterone variants (enanthate, cypionate, propionate).
This is because the injections are painful and irritating, and its short half-life necessitates frequent injections, which is a significant inconvenience.
When using testosterone suspension to improve physique and athletic performance, one must inject it once a day or more (ideally multiple times) to maintain optimal plasma levels.
These characteristics pose a major burden, especially for beginners, leading them to prefer long-estered testosterones (like enanthate and cypionate) instead.
The advantages of testosterone suspension are that it becomes active immediately upon administration, reaching peak plasma concentrations rapidly, and it contains more pure testosterone per injection than other formulations, allowing effects to be achieved with a smaller dose.
For example, for comparison, the following list shows the approximate amount of pure testosterone contained in the four most popular testosterone preparations
Testosterone Suspension 100mg (non-esterified testosterone) = 100mg of Testosterone
Testosterone Propionate 100mg = 80mg of Testosterone
Testosterone Enanthate 100mg = 70mg of Testosterone
Testosterone Cypionate 100mg = 69mg of Testosterone
Medical Testosterone Suspension Dosage
The dosage of medical testosterone suspension used clinically and medically for the treatment of hypogonadism (androgen deficiency) is 25mg administered 2-3 times per week.
Beginner, Intermediate, and Advanced Testosterone Suspension Dosages
Due to its characteristics of requiring frequent injections and causing injection pain, testosterone suspension is considered an advanced anabolic steroid.
Most of its users are advanced athletes or bodybuilders who have already experienced various steroids.
Beginner and intermediate users are often intimidated by these properties and generally prefer long-estered products.
A suitable dose for a beginner is 100mg administered every other day, with injections recommended once or more per day.
Intermediate users administer 50-100mg per day, and advanced users administer 100-200mg per day, allowing for rapid increases in strength and muscle mass at high doses.
Proper Administration and Timing for Testosterone Suspension
Testosterone suspension is an aqueous formulation containing microcrystalline testosterone suspended in water.
Before injection, the vial must be shaken to ensure the hormone is uniformly dispersed.
Due to its short half-life (~24 hours), daily injection is ideal, and sometimes multiple injections per day are used to maintain optimal plasma concentrations.
This formulation consists of microcrystals suspended in water, which can cause pain, local irritation, swelling, and redness upon injection.
Injection needles of 22-23 gauge are used, but larger needles like 21 gauge may be necessary for veterinary products containing larger crystals.
This causes discomfort, especially when frequent injections are required.
Human-grade microcrystalline formulations generally have better tolerability compared to veterinary ones.
Expected Effects and Results from Taking Testosterone Suspension
Testosterone suspension works extremely rapidly and can produce some of the fastest size and strength gains among anabolic steroids.
Because no ester is attached, some of the testosterone begins working immediately in the muscle upon injection.
It is not uncommon to see a rapid weight gain of 5-10 pounds within the first week.
Due to its fast-acting properties, this product is often used as a pre-workout supplement to enhance strength and aggression, rather than for the entire cycle.
