Ultrabol 150 mg is an oil-based cut mix injectable manufactured by British Dragon and dosed at 150 mg/mL in a 10 mL vial. It combines three compounds — drostanolone propionate, testosterone propionate, and trenbolone acetate — in a single formulation.
Ultrabol 150 mg contains a three-compound blend designed for bodybuilding contexts where fat loss and muscle preservation are primary goals. The formula combines drostanolone propionate (a non-aromatizing DHT-derived compound), testosterone propionate (a short-acting testosterone ester), and trenbolone acetate (a potent non-aromatizing trenbolone ester). All three compounds are short-acting esters, which means frequent injections are typically referenced to maintain stable blood levels.
In non-medical bodybuilding contexts, cut mixes are commonly referenced for contest preparation and cutting phases. Drostanolone propionate is often described as providing a hardening effect without water retention. Testosterone propionate serves as a base compound, providing some estrogenic support that may help mitigate joint discomfort and libido issues sometimes associated with non-aromatizing compounds. Trenbolone acetate is included for its potent effects on body composition. However, trenbolone has not been approved by the FDA for human use and is associated with significant side effects including insomnia, night sweats, and cardiovascular stress.
Because this blend contains three different compounds, each with its own side effect profile, the overall risk profile is more complex than using a single compound. The testosterone propionate component aromatizes to estrogen, while drostanolone and trenbolone do not. This means that estrogenic side effects may still occur from the testosterone component, and aromatase inhibitors may be considered in some contexts.
Ultrabol 150 mg uses MCT oil as its carrier oil, providing the oil base for the three-compound cut blend.
Ultrabol 150 mg is a three-compound injectable blend that combines a non-aromatizing DHT derivative, a short-acting testosterone ester, and a potent non-aromatizing trenbolone ester.
Each component of Ultrabol 150 mg has a distinct role in the blend. Drostanolone propionate is a DHT-derived anabolic steroid that does not aromatize to estrogen. It is commonly referenced for its hardening effects and is often described as providing a dry, defined look without water retention. Testosterone propionate is a short-acting testosterone ester with a half-life of approximately two to three days. It provides a base level of testosterone and aromatizes to estrogen, which may help with joint comfort and libido. Trenbolone acetate is a short-acting trenbolone ester with a half-life of approximately one to two days. It is known for its potent effects on body composition but also for its distinctive side effect profile.
All three compounds are short-acting esters, meaning they are typically injected every other day or daily to maintain stable blood levels. This short-acting nature allows for rapid adjustment if side effects occur, but also requires more frequent injections than long-acting preparations.
Once the esters are metabolized, the active compounds are drostanolone, testosterone, and trenbolone, respectively. The ester primarily determines the rate of release and duration of activity rather than changing the underlying properties of each compound.
All three esters in Ultrabol 150 mg are short-acting. Drostanolone propionate and testosterone propionate have half-lives of approximately two to three days, while trenbolone acetate has a half-life of approximately one to two days. This means the blend is typically injected every other day or daily to maintain stable blood levels.
British Dragon offers several cutting-oriented products as both standalone compounds and blends. Ultrabol 150 mg is distinguished by its three-compound formula combining drostanolone, testosterone, and trenbolone.
For those considering individual compounds, Mastabol 100 (drostanolone propionate), Testabol Propionate (testosterone propionate), and Trenabol 100 (trenbolone acetate) are available separately. British Dragon also offers Ultrabol 275, a higher-concentration cut mix for more experienced users.
The information below is provided for educational reference only. This product contains trenbolone, which has not been approved by the FDA for human use. Non-medical use falls outside approved indications and carries significant health risks.
In non-medical bodybuilding contexts, cut mixes such as Ultrabol 150 mg are commonly referenced in the range of 150–300 mg per week (equivalent to 1–2 mL per week). Because all three esters are short-acting, injection frequency of at least every other day is commonly referenced to maintain stable blood levels. Some users prefer daily injections to minimize fluctuations. Cycle duration is typically referenced as 6–8 weeks due to the trenbolone component's harsh side effect profile.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Bodybuilding (non-medical, moderate) | 150–200 mg / week | Every other day or 3x weekly |
| Bodybuilding (non-medical, experienced) | 200–300 mg / week | Every other day or daily |
| Contest preparation | Typically adjusted based on individual response | Per cycle protocol |
Because Ultrabol 150 mg already contains three compounds, additional stacking is less common than with single-compound products. Some users may add an oral compound such as Stanabol 10 or Oxanabol during the final weeks of a cutting phase. Others may add a low dose of a longer-acting testosterone to maintain stable levels between injections.
Trenbolone is considered an advanced compound, and combining it with drostanolone and testosterone creates a complex risk profile. Cycle structure, duration, and support compounds should be considered in the context of individual experience and health status.
The side effect profile of Ultrabol 150 mg reflects the combination of its three components. From testosterone propionate, estrogenic side effects such as water retention and gynecomastia are possible, though the presence of drostanolone may partially offset these effects. Aromatase inhibitors such as Anastrozole are sometimes referenced in this context. From trenbolone acetate, side effects may include insomnia, night sweats, increased aggression, and cardiovascular stress.
Drostanolone propionate is generally considered mild in terms of side effects, though androgenic effects such as acne and hair loss in predisposed individuals can occur. Cardiovascular health, including lipid profiles, should be monitored during use.
After completing a cycle with Ultrabol 150 mg, post-cycle therapy is commonly recommended to help restore endogenous testosterone production and support hormonal recovery. Agents such as Clomiphene and Tamoxifen are commonly referenced for this purpose.
Because all three esters are short-acting, the blend clears from the system relatively quickly, and PCT may be initiated sooner than with longer-acting preparations. PCT protocols vary based on cycle length, compounds used, and individual factors.
Dosing strategies, support compounds, and recovery protocols should be adjusted based on experience level and bloodwork where possible. The information above is for educational reference and does not constitute medical advice.
Ultrabol 150 mg contains trenbolone, which has not been approved by the FDA for human use. It is classified as a Schedule III controlled substance. Non-medical use carries significant health risks.
This product contains trenbolone, a veterinary anabolic steroid that has never been approved for human use. The FDA has approved trenbolone only as an implant for cattle to increase weight gain, and these products are explicitly labeled "Not for human use." The other components, drostanolone propionate and testosterone propionate, are also anabolic steroids with their own risk profiles.
Anabolic steroids, including those in Ultrabol 150 mg, have not been shown to enhance athletic ability. Non-medical use of this cut mix falls outside approved indications and is associated with significant health risks.
This product contains trenbolone, which has not been approved for human use. Product concentration and laboratory verification do not establish that non-medical use is safe or appropriate for an individual. The risks associated with the components of this blend are significant and may include cardiovascular, neurological, and hepatic effects.
The side effect profile of Ultrabol 150 mg reflects its three components. From trenbolone acetate, commonly reported effects include insomnia, night sweats, increased aggression, anxiety, and cardiovascular stress. A recent review noted that 90% of trenbolone users experience injurious side effects, with severe acne and gynecomastia affecting approximately one-third of users.
From testosterone propionate, estrogenic side effects such as water retention, gynecomastia, and elevated blood pressure are possible in susceptible individuals. The drostanolone component may partially offset these effects but does not eliminate them.
Androgenic effects such as acne, oily skin, and hair loss in predisposed individuals can occur from all three components. Women may experience virilization symptoms including voice deepening, clitoral enlargement, and menstrual irregularities, and this product should not be used by females.
Anabolic steroids can affect lipid profiles, typically reducing HDL cholesterol and potentially increasing LDL cholesterol. Cardiovascular health should be monitored during use.
Anabolic steroids are not appropriate for individuals with certain medical conditions. Medical evaluation should precede any consideration of use, particularly for those with existing cardiovascular disease, liver conditions, or a history of hormone-sensitive cancers.
Pregnancy and breastfeeding are absolute contraindications. Women considering use should be aware of the potential for irreversible virilization effects.
Medically supervised anabolic steroid therapy involves regular monitoring of liver function, lipid profiles, and hormone levels. However, because this product contains trenbolone which has not been approved for human use, there are no established monitoring protocols for its non-medical use. Bloodwork can help identify adverse changes, but the absence of monitoring significantly increases the risk of unrecognized adverse effects.

Answers to common questions about Ultrabol 150 mg, the cut mix blend, usage, and related topics.
Ultrabol 150 mg contains a three-compound cut mix including trenbolone acetate, which has not been approved by the FDA for human use. In non-medical bodybuilding settings, Ultrabol 150 mg is commonly referenced for cutting and recomposition phases where fat loss and muscle preservation are primary goals, though such use falls outside approved indications and carries significant health risks.
Because all three esters in Ultrabol 150 mg are short-acting, injection frequency of at least every other day is commonly referenced to maintain stable blood levels. Some users prefer daily injections to minimize fluctuations. Injection frequency should be based on individual factors and experience level.
Anabolic steroids, including those in Ultrabol 150 mg, can suppress endogenous testosterone production. In non-medical bodybuilding contexts, post-cycle therapy is commonly referenced after a cycle to support hormonal recovery. Agents such as Clomiphene and Tamoxifen are commonly discussed for this purpose. Because the esters are short-acting, PCT may be initiated sooner than with longer-acting preparations.
The three compounds in Ultrabol 150 mg have distinct roles. Drostanolone propionate is commonly referenced for hardening without water retention. Testosterone propionate provides a base with some estrogenic support. Trenbolone acetate is known for its potent effects on body composition but also for its distinctive side effect profile.
All three esters in Ultrabol 150 mg are short-acting, meaning they act relatively quickly after injection. Visible effects on physique and performance are typically referenced as taking several weeks to become apparent, depending on dose, diet, training, and individual factors. Cycle duration is typically referenced as 6–8 weeks due to the trenbolone component's side effect profile.
There is no single cutting preparation that is universally best. Cut mixes such as Ultrabol 150 mg offer convenience by combining three compounds in one injection, but they also create a more complex risk profile than using individual compounds. The appropriate approach depends on individual goals, experience level, and risk tolerance.
Ultrabol 150 mg is a lower-concentration cut mix with 150 mg/mL total, while Ultrabol 275 is a higher-concentration version at 275 mg/mL. The higher concentration means a smaller injection volume delivers a higher total dose. Ultrabol 275 is typically referenced for more experienced users.
Ultrabol 150 mg is a three-compound blend containing trenbolone acetate along with drostanolone propionate and testosterone propionate. Trenabol 100 contains only trenbolone acetate. The blend provides additional compounds that may offer complementary effects, but also introduces the risk profiles of all three components.
A milligram amount cannot be classified as appropriate or excessive without considering individual factors, experience level, and side effect tolerance. In bodybuilding contexts, 150–300 mg per week falls within commonly referenced ranges, but this does not establish that it is safe or appropriate for any individual. Non-medical use falls outside approved indications.
Ultrabol 150 mg is labeled at 150 mg of total compounds per mL, comprising drostanolone propionate 50 mg, testosterone propionate 50 mg, and trenbolone acetate 50 mg. It is supplied in a 10 mL vial, giving 1,500 mg of total labeled content per vial.
Partially. The testosterone propionate component of Ultrabol 150 mg aromatizes to estrogen, which can contribute to water retention and gynecomastia in susceptible individuals. However, drostanolone propionate and trenbolone acetate do not aromatize. The overall estrogenic effect depends on the balance of these components and individual response.
