Type II turn of receptor-bound salmon calcitonin revealed by X-ray crystallography
A more recent docking and MD simulation study demonstrates that in addition to the S1, cocaine can also bind in another new allosteric site formed by TMs 3, 9, 10, and 12 (Xu and Chen, 2020)
Standard Dosage Recommendations: Typical concentration: Available as a 10 mg/mL solution in 5 mL vials Daily dosage: 1-2 mg (0.03-0.06ml or 3-6 units) subcutaneously Alternative recommendation: 0.2 mL delivered subcutaneously once daily Injection concentration range: 0.1% to 1.0% Administration Schedule: Frequency: Daily injections, preferably at the same time each day Recommended schedule: Monday through Friday (with weekends off) Important note: Injectable GHK-Cu should be administered under professional supervision due to risks associated with self-injection Oral/Ingestible Options Oral administration of GHK-Cu requires special formulation to prevent breakdown in the digestive system
