oh josh...........u silly billy..........one day u will grow up
No. It is pretty obvious you have no clue and yet continue to try and give people advice.
yes all AAS will have a toll on the HPTA, but supression is based on doseages and lenght of tyme rum
As little as 2.5mg of var can cause suppression. The dosage and lenth of time will determine HOW suppressed you become but there is no doubt that var is suppressive.

Abstract
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.
