Pharmaqo – 1-Test Cyp (DHB): Uses, Effects, Side Effects, and Safety Guide
Pharmaqo – 1-Test Cyp (DHB) (Dihydroboldenone Cypionate)
Pharmaqo – 1-Test Cyp (DHB) is marketed as an injectable anabolic-androgenic steroid (AAS) containing dihydroboldenone cypionate, also known as 1-Testosterone Cypionate or DHB.
General product information:
- Product Name: Pharmaqo – 1-Test Cyp (DHB)
- Active Ingredient: Dihydroboldenone Cypionate (1-Testosterone Cypionate)
- Common Names: DHB, 1-Test Cyp, 1-Testosterone Cypionate
- Dosage Form: Injectable oil-based solution
- Drug Class: Anabolic-androgenic steroid (AAS)
Independent laboratory testing of a Pharmaqo Labs 1-Test Cyp (DHB) sample reported the presence of 1-Testosterone Cypionate at a measured concentration close to the labeled amount, although laboratory results can vary by batch and should not replace regulated quality assurance.
Products obtained outside regulated pharmaceutical supply chains may vary in authenticity, potency, purity, sterility, and manufacturing quality.
What Is Pharmaqo – 1-Test Cyp (DHB)?

Pharmaqo – 1-Test Cyp (DHB) is marketed as an injectable preparation containing dihydroboldenone cypionate, a modified derivative related to boldenone.
General product details:
- Compound: Dihydroboldenone Cypionate
- Alternative Name: 1-Testosterone Cypionate
- Administration: Intramuscular injection
- Category: Injectable anabolic steroid
Despite the name 1-Testosterone, DHB is not testosterone replacement therapy. It is a separate anabolic-androgenic steroid compound.
What Is Dihydroboldenone (DHB)?
Dihydroboldenone (DHB), also called 1-Testosterone, is a synthetic anabolic steroid related to boldenone.
Its chemical characteristics include:
- Derivative of boldenone
- Strong androgen receptor activity
- Non-aromatizing structure
- Injectable cypionate ester formulation
DHB is mainly discussed in performance-enhancing contexts and is not an approved routine human medication in many countries.
How Does DHB Work?
DHB works by interacting with androgen receptors throughout the body.
Androgen receptor activation may influence:
- Protein synthesis
- Muscle tissue maintenance
- Nitrogen retention
- Red blood cell production
- Hormonal signaling
Like other anabolic-androgenic steroids, DHB can affect the body’s natural hormone production.
Medical Background
Dihydroboldenone is not widely used as an approved pharmaceutical treatment.
Unlike medically established hormone therapies, DHB does not have a broad history of approved clinical applications in humans.
Research and discussion around DHB largely come from anabolic steroid chemistry, laboratory analysis, and non-medical performance-enhancement communities.
DHB in Fitness and Bodybuilding Discussions
Within bodybuilding communities, DHB is commonly discussed because of associations with:
- Lean muscle development
- Strength improvements
- Reduced water retention compared with estrogen-converting compounds
- Muscle hardness and density
These uses are outside approved medical indications and may carry significant health risks.
Hormonal Effects
Like other anabolic-androgenic steroids, DHB may suppress natural hormone production.
Potential hormonal effects include:
- Reduced natural testosterone production
- Reduced LH and FSH activity
- Fertility changes
- Libido changes
- Hormonal imbalance
Recovery after suppression can vary significantly between individuals.
Estrogen Considerations
DHB is generally considered a non-aromatizing compound, meaning it does not significantly convert into estrogen.
However, estrogen balance may still be affected indirectly, especially when combined with other hormone-active compounds.
Possible Side Effects
Potential side effects associated with anabolic-androgenic steroids may include:
- Acne
- Oily skin
- Hair loss in genetically susceptible individuals
- Mood changes
- Increased blood pressure
- Hormonal suppression
- Changes in cholesterol levels
Women exposed to androgenic steroids may experience:
- Voice deepening
- Increased facial or body hair
- Menstrual changes
- Clitoral enlargement
Some androgenic effects may be irreversible.
Cardiovascular Considerations
DHB and other anabolic steroids may negatively affect cardiovascular risk factors.
Potential concerns include:
- Reduced HDL (“good”) cholesterol
- Increased LDL (“bad”) cholesterol
- Elevated blood pressure
- Increased cardiovascular strain
Medical monitoring may include assessment of blood pressure, lipid profile, and other health markers.
Injection-Related Considerations
Injectable products may involve risks including:
- Injection-site irritation
- Pain or swelling
- Infection
- Sterility concerns
- Contamination risks
The safety of injectable products depends heavily on manufacturing quality and sterile handling.
Product Quality Considerations
Products obtained outside regulated pharmaceutical systems may vary in:
- Active ingredient accuracy
- Concentration
- Sterility
- Purity
- Manufacturing standards
Potential concerns include:
- Counterfeit products
- Incorrect labeling
- Contamination
- Batch inconsistency
Independent testing has been used to evaluate some Pharmaqo DHB-related products, but testing results apply only to specific samples and batches.
Storage Recommendations
Injectable products should generally be stored:
- At controlled room temperature
- Away from direct sunlight
- Protected from excessive heat
- In original packaging
- Out of reach of children
Do not use products with:
- Damaged packaging
- Visible particles
- Unusual discoloration
- Expired labeling
