    Thought this was interesting

    Meyer Children's Hospital, Rambam Medical Center, Haifa, Israel.

    BACKGROUND/AIMS: Two modalities of androgen therapy prevail in the treatment of constitutional delay of growth (CDG): monthly injections of testosterone or daily tablets of the non-aromatizable oxandrolone. The present study was undertaken to prospectively compare both compounds and dose. METHODS: Thirty patients with CDG were the subjects of this study. The protocol required that they all be at age 12-14 years with a bone age delay of more than 2 'years', height less than -2 SDS and growth velocity less than -0.5 SDS. The subjects were at a Tanner stage 1 or 2 and testicular volume were no larger than 4 ml. They were randomly assigned into 3 treatment groups: group 1 patients received monthly injections of 25 mg testosterone propionate -enanthate ; group 2 patients received monthly injections of 50 mg testosterone propionate -enanthate; group 3 patients received oral oxandrolone at a weekly dose of 0.7 mg/kg. Treatment was given for a period of 6 months and follow-up commenced 6 months later and yearly thereafter for 2 years. RESULTS: Height velocity and height increased significantly only in groups 2 and 3. Bone age advanced most in group 2. Puberty progressed faster in that group as compared with group 3. The predicted adult height before and 2 years after completion of treatment remained unchanged in the two testosterone groups. It increased significantly in the oxandrolone group from a mean 169.8 cm before therapy to a mean 177.5 cm 2 years after completion of therapy. Peak GH levels were significantly higher on both testosterone 50 mg and oxandrolone, as compared to pretreatment levels. The increment was significantly greater in group 2 as was the increment in serum IGF-1 and IGFBP3. CONCLUSIONS: These results imply that 6 months of testosterone injections at a dose of 50 mg, but not 25 mg, is an effective and safe treatment for patients with CDG, with no considerable impact on final height prediction. On the other hand, daily oxandrolone treatment, starting at age 12-14 years, may increase the predicted final adult height. Copyright 2003 S. Karger AG, Basel

    interesting, but i thought they had always used oxandrolone for women and children with growth deficits, irregardless its nice to see actual studies with steroids , good stuff

    That's interesting. I guess the low dose of test didn't fuse their growth plates. It would be interesting if they did another study to see what the maximum dosage was before it fuses them

    Short-term oxandrolone administration stimulates net muscle protein synthesis in young men.

    Sheffield-Moore M, Urban RJ, Wolf SE, Jiang J, Catlin DH, Herndon DN, Wolfe RR, Ferrando AA.

    Department of Surgery, University of Texas Medical Branch, and Shriners Burn Hospital for Children, Galveston 77550, USA. melmoore@utmb.edu

    Short term administration of testosterone stimulates net protein synthesis in healthy men. We investigated whether oxandrolone [Oxandrin (OX)], a synthetic analog of testosterone, would improve net muscle protein synthesis and transport of amino acids across the leg. Six healthy men [22+/-1 (+/-SE) yr] were studied in the postabsorptive state before and after 5 days of oral OX (15 mg/day). Muscle protein synthesis and breakdown were determined by a three-compartment model using stable isotopic data obtained from femoral arterio-venous sampling and muscle biopsy. The precursor-product method was used to determine muscle protein fractional synthetic rates. Fractional breakdown rates were also directly calculated. Total messenger ribonucleic acid (mRNA) concentrations of skeletal muscle insulin -like growth factor I and androgen receptor (AR) were determined using RT-PCR. Model-derived muscle protein synthesis increased from 53.5+/-3 to 68.3+/-5 (mean+/-SE) nmol/min.100 mL/leg (P < 0.05), whereas protein breakdown was unchanged. Inward transport of amino acids remained unchanged with OX, whereas outward transport decreased (P < 0.05). The fractional synthetic rate increased 44% (P < 0.05) after OX administration, with no change in fractional breakdown rate. Therefore, the net balance between synthesis and breakdown became more positive with both methodologies (P < 0.05) and was not different from zero. Further, RT-PCR showed that OX administration significantly increased mRNA concentrations of skeletal muscle AR without changing insulin-like growth factor I mRNA concentrations. We conclude that short term OX administration stimulated an increase in skeletal muscle protein synthesis and improved intracellular reutilization of amino acids. The mechanism for this stimulation may be related to an OX-induced increase in AR expression in skeletal muscle.

    Effect of low dose oxandrolone and testosterone treatment on the pituitary-testicular and GH axes in boys with constitutional delay of growth and puberty.

    Crowne EC, Wallace WH, Moore C, Mitchell R, Robertson WH, Holly JM, Shalet SM.

    Department of Endocrinology, Christie Hospital Trust, Manchester, UK.

    OBJECTIVE: To investigate the effect of low dose oxandrolone and testosterone on the pituitary-testicular and GH-IGF-I axes. DESIGN: Prospective double-blind placebo-controlled trial. PATIENTS: Sixteen boys with constitutional delay of growth and puberty (CDGP) with testicular volumes 4-6 ml were randomized to 3 months treatment: Group 1 (n = 5), daily placebo: Group 2 (n = 5), 2.5 mg oxandrolone daily or Group 3 (n = 6), 50 mg testosterone monthly intramuscular injections with assessment (growth, pubertal development and overnight hormone profiles) at 0, 3, 6 and 12 months. MAIN OUTCOME MEASURES: LH and GH profiles (15-minute samples) were analysed by peak detection (Pulsar), Fourier transformation and autocorrelation. Testosterone levels were measured hourly and insulin , SHBG, IGF-I, and IGFBP-3 levels at 0800 h. Statistical analysis was by multivariate analysis of variance for repeated measures. RESULTS: LH and testosterone parameters increased significantly with time in all 16 (LH AUC, P < 0.001; peak amplitude, P = 0.02; number of peaks, P = 0.02; testosterone AUC, P = 0.02; morning testosterone, P = 0.002). In Group 2, however, LH and testosterone parameters decreased at 3 months followed by a rebound increase at 6 and 12 months. SHBG levels were markedly reduced at 3 months (P = 0.006) and a wider range of dominant GH frequencies was present although GH AUC was not increased until 6 months, with an increase in GH pulse frequency but not amplitude. IGF-I levels were increased at both 3 and 12 months. In Group 3, pituitary-testicular suppression was not apparent, but GH levels increased with an increase in GH amplitude at 3 and 12 months. CONCLUSION: Oxandrolone transiently suppressed the pituitary-testicular axis and altered GH pulsatility. Testosterone increased GH via amplitude modulation.

    Oral anabolic steroid treatment, but not parenteral androgen treatment, decreases abdominal fat in obese, older men.

    Lovejoy JC, Bray GA, Greeson CS, Klemperer M, Morris J, Partington C, Tulley R.

    Pennington Biomedical Research Center, Baton Rouge, Louisiana 70808-4124, USA.

    OBJECTIVE: To compare the effects of testosterone enanthate (TE), anabolic steroid (AS) or placebo (PL) on regional fat distribution and health risk factors in obese middle-aged men undergoing weight loss by dietary means. DESIGN: Randomized, double-blind, placebo-controlled clinical trial, carried out for 9 months with primary assessments at 3 month intervals. Due to adverse blood lipid changes, the AS group was switched from oral oxandrolone (ASOX) to parenteral nandrolone decaoate (ASND) after the 3 month assessment point. SUBJECTS: Thirty healthy, obese men, aged 40-60 years, with serum testosterone (T) levels in the low-normal range (2-5 ng/mL). MAIN OUTCOME MEASURES: Abdominal fat distribution and thigh muscle volume by CT scan, body composition by dual energy X-ray absorptiometry (DEXA), insulin sensitivity by the Minimal Model method, blood lipids, blood chemistry, blood pressure, thyroid hormones and urological parameters. RESULTS: After 3 months, there was a significantly greater decrease in subcutaneous (SQ) abdominal fat in the ASOX group compared to the TE and PL groups although body weight changes did not differ by treatment group. There was also a tendency for the ASOX group to exhibit greater losses in visceral fat, and the absolute level of visceral fat in this group was significantly lower at 3 months than in the TE and PL groups. There were significant main effects of treatment at 3 months on serum T and free T (increased in the TE group and decreased in the ASOX group) and on thyroid hormone parameters (T4 and T3 resin uptake significantly decreased in the ASOX group compared with the other two groups). There was a significant decrease in HDL-C, and increase in LDL-C in the ASOX group, which led to their being switched to the parenteral nandrolone decanoate (ASND) after 3 months. ASND had opposite effects on visceral fat from ASOX, producing a significant increase from 3 to 9 months while continuing to decrease SQ abdominal fat. ASND treatment also decreased thigh muscle area, while ASOX treatment increased high muscle. ASND reversed the effects of ASOX on lipoproteins and thyroid hormones. The previously reported effect of T to decrease visceral fat was not observed, in fact, visceral fat in the TE group increased slightly from 3 to 9 months, although SQ fat continued to decrease. Neither TE nor AS treatment resulted in any change in urologic parameters. CONCLUSIONS: Oral oxandrolone decreased SQ abdominal fat more than TE or weight loss alone and also tended to produce favorable changes in visceral fat. TE and ASND injections given every 2 weeks had similar effects to weight loss alone on regional body fat. Most of the beneficial effects observed on metabolic and cardiovascular risk factors were due to weight loss per se. These results suggest that SQ and visceral abdominal fat can be independently modulated by androgens and that at least some anabolic steroids are capable of influencing abdominal fat.

    i read that methandrostenlone actually stops growth ,because it calcifies (don't know if that the correct term) all the bones of a growing teen ,cause it's used to prevent/fight osteoporosis and old people. Don't belive much about that cause i was 14 and 5.10" when i started taking d-bol and i'm 22 6.3"
