Yes, when administered by qualified healthcare professionals
The most studied peptides for pain include BPC-157 (tissue protection and healing), TB-500 (mobility and recovery), and GHK-Cu (collagen support)
[13] In a newly diagnosed vitamin B 12 -deficient patient, normally defined as when serum levels are less than 200 pg/ml, daily IM injections of hydroxocobalamin up to 1,000 g (1 mg) per day are given to replenish the body's depleted cobalamin stores
When administered subcutaneously or intravenously, GHK-Cu has systemic effects that go well beyond hair follicles
Unlike testosterone therapy, estrogen therapy, growth hormone therapy, or other hormone-based treatments, BPC-157 is generally not considered a hormone replacement treatment
