The supernatants were collected for further protein quantification using BCA protein assay kit after centrifugation at 12,000 g at 4C for 15 minutes

Start low, go slow Beginner approach: Start with single peptide (BPC-157 recommended) Use minimum effective dose Run for 4-8 weeks before adding anything Assess tolerance and results Dose escalation: Begin at lowest recommended dose Increase by 25% every 2-3 weeks if needed Stop increasing when seeing good results More isn't always better Adding peptides: Add one new peptide at a time Wait 2-4 weeks between additions This identifies which peptide causes any issues Proper injection technique Critical for safety: Always use sterile technique Clean injection sites with alcohol Rotate injection sites (prevent tissue damage) Use appropriate needle size (insulin syringes for subcutaneous) Never share needles Infection prevention: New sterile needle every injection Wash hands thoroughly Wipe vial top before drawing Don't touch needle to anything See our complete peptide injections guide for detailed technique

As is recently suggested, proline can be considered as a functional amino acids (Wu 2010, 2014
Peptides Will arrive in a lyophilized (powder) form for maximum stability
