| 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

 •	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).
