The oxygen non-bonding electrons in alcohols and ethers do not give rise to absorption above 160 nm
As new studies emerge and scientific understanding advances, BPC-157 will remain a peptide worth watching.
Calculating your working concentration Use this formula: Concentration (mcg/mL) = Total peptide (mcg) Volume of diluent added (mL) | Vial size | Bacteriostatic water added | Resulting concentration | |-----------|---------------------------|------------------------| | 2 mg (2,000 mcg) | 1 mL | 2,000 mcg/mL | | 2 mg (2,000 mcg) | 2 mL | 1,000 mcg/mL | | 6 mg (6,000 mcg) | 3 mL | 2,000 mcg/mL | | 6 mg (6,000 mcg) | 6 mL | 1,000 mcg/mL | Most prescribers prefer the 1,000 mcg/mL concentration because the injection volume for a 200 to 500 mcg dose falls between 0.2 mL and 0.5 mL
But with a 2mg/mL concentration (5mL of water added), that same 4mg dose requires 2.0mL of liquid, which is an entire insulin syringe worth and creates a large, uncomfortable injection volume
