[QUOTE="madman, post: 272483, member: 13851"] Did you look over the thread I dropped in 2020? Have you read the full paper from 2021 which includes any limitations in the study? TT troughs (IM vs sub-q) were nothing to brag about. Even then keep in mind this is not true trough (7 days post-injection) as blood was drawn 5-6 days after the last injection. [B][I]*Men were either treated with IM-TC alone, SCTE-AI alone or [U]started with IM-TC and crossed over to SCTE-AI with at least 6 weeks of washout between the 2 treatment modalities[/U]. [U]Dosing for IM-TC and SCTE-AI was 100 mg weekly[/U].[/I][/B] [I][B]*Serum values of TT (280 to 1,100 ng/dL), E2 (10 to 50 pg/mL), HCT (38.8% to 50.0%) and PSA (<2.5 ng/mL) were drawn prior to initiation of TRT and at 12-week followup. [/B][/I][B][I][B][U]B[/U][/B][U][B]aseline laboratory blood [/B]draws were specified to occur in the morning prior to 10:00 a.m. and 5-6 days after their last injection to observe trough TT values[/U]. *After an average follow-up of 14.2 weeks after initiating TRT, [U]both cohorts had significant increases in trough TT compared to their baseline levels[/U] (IM-TC:313.6 ng/dL to 536.4 ng/dL, p <0.001; SCTE-AI: 246.6ng/dL to 552.8 ng/dL, p <0.001)[/I][/B] [I][B]*Post-therapy, the SCTE-AI cohort had significantly lower, HCT and E2, [/B][/I][B][I][B][U]while [/U][/B][U]TT[/U] and PSA [U]levels were not significantly different between the treatment arms[/U].[/I][/B] [I][B]post #26 (full paper)[/B][/I] [URL unfurl="true"]https://www.excelmale.com/forum/threads/intramuscular-versus-subcutaneous-testosterone-injections-effect-on-tt-hematocrit-e2-and-psa.22223/[/URL] [B]Limitations[/B] [I]This is the first study of the novel SCTE-AI indirect comparison to another TRT modality for the treatment of hypogonadism in men.
