TRT isn't a peptide. It's exogenous testosterone. But it shows up on this platform because it's commonly stacked with peptides like gonadorelin or HCG for fertility preservation. Testosterone cypionate comes as a ready to use oil solution at 200 mg/mL. No reconstitution math here; you're drawing volume directly. For an 80 mg dose, that's 0.4 mL (40 units on a 100 unit insulin syringe). For the common split dose of 75 mg twice weekly, draw 0.375 mL (37 to 38 units). At 100 mg per injection, you need 0.5 mL (50 units). The thing most beginners miss: warm the vial in your hands for 60 seconds before drawing. Cold oil is thick and painful going in. Splitting your weekly dose into two injections every 3.5 days produces more stable blood levels and reduces estrogen spikes; the community figured this out before the clinical literature caught up. Get baseline bloodwork before your first injection. Total testosterone, free testosterone, estradiol (sensitive assay), SHBG, CBC with hematocrit, PSA, and a lipid panel. Non negotiable.
