DHB (Dihydroboldenone Cypionate) 100mg/ml
DHB, short for Dihydroboldenone, is also known as 1-Testosterone. This product uses the cypionate ester and contains 100mg of Dihydroboldenone Cypionate per ml, with 10ml providing 1,000mg total. In bodybuilding, DHB is most commonly selected for lean-mass, strength and recomposition-focused cycles rather than for maximum water-weight gain.

Current Thai Anabolics practice
These are non-medical bodybuilding reference amounts, not an approved clinical dosing schedule. Human clinical dosing and pharmacokinetic studies for Dihydroboldenone Cypionate are extremely limited, so the current Thai Anabolics dosage is kept clearly separate from the published laboratory research on 1-Testosterone.[1][3]
Compound identity
What Is DHB / 1-Testosterone?
Dihydroboldenone is 1-Testosterone, chemically described as 17β-hydroxy-5α-androst-1-en-3-one. It can also be understood as the 5α-reduced form of Boldenone.[2]
Laboratory research found that 1-Testosterone binds selectively to the androgen receptor and has potent androgenic and anabolic activity. In an animal model, an equimolar dose produced androgen-sensitive muscle and reproductive-tissue effects comparable with testosterone propionate.[1]
The important limitation: those findings are preclinical. There is no established medical indication or validated human bodybuilding dose for DHB Cypionate.
Non-aromatizing structure
Does DHB Convert to Estrogen?
Published analytical literature describes 1-Testosterone as a 5α-reduced androgen that cannot aromatize to estrogens.[2]
That is one reason DHB is associated with leaner-looking gains and less estrogen-driven water retention than strongly aromatizing compounds. It does not mean a complete cycle is automatically free of estrogenic effects if testosterone or another aromatizing steroid is used alongside it.
Lean-mass use
Why Bodybuilders Choose DHB
DHB is generally selected when the goal is lean muscle, strength and body recomposition without relying on estrogen-driven water retention for rapid scale-weight increases.
The evidence supports describing 1-Testosterone as a potent anabolic-androgenic steroid; claims about exact muscle gain, fat loss or a specific “anabolic ratio” should not be treated as established human outcomes.[1]

DHB vs Boldenone
| Feature | DHB / 1-Testosterone | Boldenone |
|---|---|---|
| Relationship | 5α-reduced form of Boldenone | Parent Δ1 androgen |
| Aromatization | Does not aromatize | Different estrogen-conversion profile |
| TA product strength | 100mg/ml | Separate Boldenone product |
| Human DHB evidence | DHB-specific human clinical data are very limited | |
The names are chemically related, but DHB should not be treated as simply “stronger Equipoise.” They are different steroid structures with different metabolism and user profiles.
The exact injectable form
Dihydroboldenone Cypionate Is a Documented Injectable Steroid
A 2021 U.S. FDA laboratory paper identified 17β-hydroxy-5α-androst-1-en-3-one cypionate in an injectable bodybuilding product using HPLC-UV, high-resolution mass spectrometry, NMR and GC-MS.[3]
That paper is useful because it confirms the exact cypionate ester exists as an injectable form of 1-Testosterone. It does not establish a human half-life, approved injection frequency or clinical bodybuilding protocol, so this page does not invent those numbers.
User-reported practical issue
DHB & Post-Injection Discomfort
DHB has a reputation among experienced users for causing more post-injection soreness than many other oil-based injectables.
This is best treated as user-reported experience, not a clinically quantified property of DHB. The current 100mg/ml concentration and twice-weekly Thai Anabolics schedule are displayed clearly so customers know the exact injectable format they are buying.
After a cycle
PCT After DHB
DHB is a potent anabolic-androgenic steroid and should be treated as suppressive to endogenous testosterone production rather than as a compound that leaves the hypothalamic-pituitary-testicular axis unaffected.[1]
PCT decisions should reflect the entire cycle and all esters used. Because a validated human DHB-Cypionate pharmacokinetic profile is not available, this page does not invent a precise evidence-based “X days after the last DHB injection” rule. See PCT products in Thailand →
Product documentation
Current DHB Testing Status
There is currently no product-specific third-party laboratory report available for this DHB product.
For that reason, this page does not display a report number, batch-specific potency result, HPLC result, purity percentage or lab-report image for the current DHB stock. See Product Testing & Authenticity →
