Some remarkable results are the decline of PSA after combination of metformin with bicalutamide after 8 weeks (42.1% bicalutamide + metformin vs 11.1% only bicalutamide) in PC patients with overweight (ClinicalTrial.gov ID NCT02614859), and with castration after 7 months (placebo PSA 58.2 ng/mL vs metformin PSA 8.36 ng/mL, ClinicalTrial.gov ID NCT01620593, [191]), and its detection in the prostatic tissue after consumption for 12 weeks, but without changes in tumor progression markers (ClinicalTrials.gov ID NCT01433913, [192])
The preservative allows multi-dose use for up to 28 days when refrigerated, making bacteriostatic water peptides preparation ideal for protocols that require repeated access to the same vial
It is evident from the various studies
