Safety Questions Before Considering Any Peptide Protocol The safest way to read any dsip peptide dosage claim is to ask what safety information is missing
However, only Methylcobalamin is biologically active without conversion

this off-label use is not backed by the same level of controlled human trial evidence as the lipodystrophy indication Known risks and side effects: Injection site reactions, including erythema, pruritus, pain, and bruising at the injection site Arthralgia (joint pain) and peripheral edema (fluid retention), recognized class effects of GH-axis stimulation Increases in blood glucose and reduced insulin sensitivity, with clinical trials showing a higher rate of elevated HbA1c and new-onset hyperglycemia versus placebo Formation of anti-tesamorelin antibodies, reported in a substantial proportion of treated patients, with unclear long-term clinical significance Contraindicated in people with active malignancy, pituitary or hypothalamic disruption, or pregnancy, per FDA labeling Evidence snapshot: The strongest evidence is a set of Phase 3 human randomized controlled trials that supported FDA approval of tesamorelin for reducing visceral abdominal fat in HIV-associated lipodystrophy (approved 2010), plus a separate placebo-controlled human RCT (Baker et al., 2012, Archives of Neurology) showing improved executive function in older adults

Freeze-thaw cycles cause irreversible peptide structural damagea single freeze-thaw event can reduce GHK-Cu potency by 2030%, making refrigeration (not freezing) the correct storage protocol for reconstituted solutions
And you have no idea how much of one goes into the other
