Nessa dose, e por apenas 02 meses, não vai suprimir o eixo, mesmo porque, se usada em dose única, vai ficar pouco tempo no corpo ao longo do dia.
Inclusive alguns atletas têm usado a testo (que tem maior probabilidade de suprimir o eixo) em gel no cruise: esta é uma vantagem da testo em gel, que quando usada pela manhã, quando for à noite, o corpo ainda vai produzir alguma testosterona endógena.

A small study of boys >13 years with constitutional delay of puberty suggested that Ox (n = 5) may result in temporary suppression of the pituitary-gonadal axis followed by an increase in serum LH and testosterone with corresponding increase in testicular volume (16). In another study that included younger boys with growth delay (9 to 14 years), 40 of the 46 participants entered puberty within the follow-up period (mean of 9 months) (17). These data are consistent with our study results, although notably endogenous puberty is typically desired in boys with constitutional delay of puberty. In contrast, use of Ox in burn victims does not seem to effect virilization or testicular function despite the use of higher doses. In one study of 70 burn victims treated for 1 year with 0.1 mg/kg/d of Ox starting at a mean age of 8, virilization was not observed in any subjects (18). In addition, TT concentrations were not different between Ox and control groups. Testicular volumes and pubertal status were not reported in this study, and pre- and postpubertal subjects of both sexes were analyzed together, potentially masking effects unique to prepubertal boys. In addition, given that our cohort experienced gonadarche at a median of 18 months into Ox treatment, it is possible the effects on the gonadal axis would not yet be apparent with only 1 year of treatment.
The recognition that chronic prepubertal sex steroid exposure may result in early activation of the hypothalamic-pituitary-gonadal axis is not unique. Poorly controlled congenital adrenal hyperplasia and McCune Albright syndrome, resulting in chronically elevated testosterone and estrogen concentrations, respectively, are well known to lead to earlier central puberty (19, 20). However, both of these conditions are associated with significant bone age advancement, and central puberty often commences when the bone age reaches a pubertal age. In contrast, the boys treated with Ox in our study reached gonadarche at a significantly younger bone age than would be expected. Prolonged prepubertal exposure to Ox and other sex steroids may interrupt the normal suppression of the hypothalamic-pituitary-gonadal axis in at least a subset of children, and this may be a useful model in studying disorders of pubertal development and/or treatment of delayed puberty.

[...]Treatment of severely burned children with oxandrolone has been the focus of a number of clinical trials. Jeschke and colleagues demonstrated that oxandrolone treatment resulted in a shorter length of hospital stay, decreased lean body mass loss, improved hepatic protein synthesis and no side effects on the hormonal axis postburn. The authors did note, however, an increase in liver enzymes" [...] (In: Anabolic and anticatabolic agents used in burn care: what is known and what is yet to be learned.).
Na dose e no período dito, não creio. Pode até diminuir algo, mas suprimir o eixo, não.
