| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| The purpose of this placebo controlled pilot trial is to determine the preliminary effect and safety of a 12 week multimodal intervention initiated during admission in the acute ward after hip fracture surgery. The intervention under investigation is a combination therapy consisting of physiotherapy (functional, balance and strength training), protein- dense nutritional supplement and nandrolone decanoate (Deca-Durabolin) supplement on improving the fractured limb knee-extension muscle strength at a 14 week follow-up. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
 | 
| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
•	Patients who have undergone surgery for a hip fracture at Amager-Hvidovre University Hospital and admitted at the Hip Fracture Unit at the hospital •	Age >=65 years •	Ability to speak and understand Danish and with a Danish Social Security Number •	Able to give written informed consent •	Residing at home and  with an independent pre-fracture indoor walking ability (NMS≥2) 
 
 | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
•	Postoperative weight-bearing restrictions •	Multiple fractures •	Terminal illness •	Patients unable/unwilling to cooperate on testing and rehabilitation •	Planned/elective hospitalization within the trial period. •	Cognitive dysfunction determined by chart review, reported by nursing staff, or observed by trained research staff (not alert or oriented, dementia, active delirium) •	Uncontrolled blood pressure (systolic > 150 mmHg, or diastolic > 100 mmHg) •	Heart disease in the form of peri-, myo- or endocarditis.  •	History of stroke with motor disability. •	Heart failure (NYHA class III and IV) •	Evidence of kidney failure or renal impairment (estimated glomerular filtration rate < 30 mL/min/1.73 m2 or serum creatinine >200μmol/L) •	Abnormal liver function tests (alanine aminotransferase, γ-glutamyltransferase, bilirubin, or alkaline phosphatase >2 times the upper limit of normal) or history of hepatic tumor. •	Elevated hematocrit ≥ 50% •	History of breast or prostate cancer •	Abnormally elevated serum PSA corresponding to PSA < 4.0 µg/L (60–70 years), PSA < 5.0 µg/L (>70 years).  •	Allergic to any ingredient in the Deca-Durabolin solution (Nandrolone, benzyl alcohol, arachis oil (peanut-oil) and allergy to peanuts or soya).

 | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| •	Change in maximal isometric knee-extension strength (Nm/Kg) in the fractured limb (Maximal Voluntary Torque (MVT) per kilo body mass) from baseline to the 14 week follow-up.  |
