Description

Dihydroboldenone Cypionate, also known as 1-Testosterone, is an anabolic steroid derived from boldenone (equipoise). It shares a similar structure to Primobolan (methenolone), but lacks the additional 1-methyl group found in Primobolan to enhance oral bioavailability.

Dihydroboldenone is a potent anabolic agent with moderate androgenic properties. Rat assays indicate that it is approximately twice as anabolic as testosterone propionate, while maintaining a similar level of androgenicity. This results in an anabolic-to-androgenic ratio of approximately 2. Bodybuilders value 1-Testosterone for its ability to promote significant muscle gains without excessive water retention or pronounced side effects.

Derived from dihydrotestosterone, 1-Testosterone contains an additional double bond between carbons 1 and 2 (1-ene). This modification stabilizes the 3-keto group and enhances the steroid's anabolic properties.

1-Testosterone is considered a non-estrogenic steroid, as it does not exhibit estrogen-related side effects such as gynecomastia, fat deposition, or visible water retention. Muscle gains achieved with 1-Testosterone are typically of high quality, without the excessive bulk often associated with highly aromatizable steroids. Therefore, it is favored during cutting phases when minimizing water and fat retention is a primary concern.

Due to its weak aromatization nature, 1-Testosterone is expected to have a stronger negative impact on hepatic cholesterol management compared to testosterone or nandrolone. However, its effect is weaker than most c-17 alpha-alkylated steroids.

Like all anabolic/androgenic steroids, 1-Testosterone may have adverse effects on blood pressure, triglyceride levels, endothelial relaxation, and left ventricular hypertrophy, potentially increasing the risk of cardiovascular disease and myocardial infarction. It may cause slight irritation when injected and can produce skin/tissue redness and irritation with both injectable and transdermal delivery methods. Some users may experience a burning sensation during urination while using 1-Testosterone products. Although the cause of this side effect is poorly understood, it is generally considered an inconvenience rather than a dangerous issue. 1-Testosterone affects hematocrit less than boldenone itself. It is a compound similar to Primobolan but with greater strength gains.

Effects:

Lean muscle gains accompanied by reductions in body fat
Twice as anabolic as testosterone
No estrogen-related side effects like gynecomastia
Less androgenic than testosterone
Promotes significant strength gains
No water retention
Suitable for both bulking and cutting phases

Side effects:

Oily skin and acne
Irritation at the injection site
Increased body and facial hair growth
Male pattern hair loss
Potential virilizing effects and clitoral enlargement in women
Reduction of HDL (good) cholesterol and increase of LDL (bad) cholesterol, potentially shifting the HDL to LDL balance in favor of arteriosclerosis
Rarely increases blood pressure
Possible mild liver toxicity

Profile

Half-life: 6-8 days
Frequency of injections: 5-7 days

Dosage

1-Testosterone was never approved for human use, so prescribing guidelines are unavailable. For physique- or performance-enhancing purposes, a daily dosage typically ranges from 100-250 mg with oil-solubilized soft gels or 75-100 mg daily when applied transdermally. Injectable dosages would fall within the range of 100-400 mg per week (as 1-Testosterone Cypionate). The drug is typically used in cycles lasting 6-12 weeks.
