Nandrolone Phenylpropionate
Also known as: NPP, Durabolin
Nandrolone Phenylpropionate is the shorter-estered version of Nandrolone Decanoate. It provides the same anabolic benefits as Deca but with a faster onset and clearance, allowing for more precise dosing control and quicker recovery of natural hormonal function after discontinuation.

Intermediate| CAS Number | 62-90-8 |
| Molecular Formula | C27H34O3 |
| Class | Steroid |
| Category | Classic Steroids |
Mechanism of Action
Pharmacologically identical to Nandrolone Decanoate once the ester is cleaved. The phenylpropionate ester provides a half-life of approximately 2.7 days, resulting in faster peak blood levels and quicker clearance compared to the decanoate ester.
Dosing Research
Typically dosed at 100-200 mg every other day or three times per week for performance enhancement. Total weekly doses range from 300-600 mg. Shorter cycles of 8-12 weeks are possible due to the faster-acting ester. Must be used alongside a testosterone base.
Side Effects & Risks
Same side effect profile as Nandrolone Decanoate including progestogenic effects, HPTA suppression, and cardiovascular strain. However, side effects may be easier to manage due to faster clearance. Injection site soreness may be more frequent due to higher injection frequency.

Testosterone Enanthate
SteroidTestosterone Enanthate is one of the most widely used testosterone esters for hormone replacement therapy and performance enhancement. It features a long-acting enanthate ester that provides sustained release over approximately 1-2 weeks, making it one of the most convenient injectable testosterone formulations.
Testosterone Cypionate
SteroidTestosterone Cypionate is a long-acting testosterone ester very similar in pharmacokinetics to Testosterone Enanthate. It is the most commonly prescribed form of testosterone in the United States for hormone replacement therapy and is widely used in performance enhancement contexts.
Testosterone Propionate
SteroidTestosterone Propionate is a short-acting testosterone ester that requires more frequent injections than longer-estered variants. It provides faster onset and clearance, making it preferred for shorter cycles, contest preparation, or situations where rapid clearance is desired.
Oxandrolone
SteroidOxandrolone (Anavar) is one of the mildest and most well-studied oral anabolic steroids. Originally developed for medical use in burn patients, muscle wasting, and osteoporosis, it is valued in performance enhancement for producing lean, dry gains with minimal side effects. It is one of the few steroids prescribed to women and children in clinical settings.
