Illustratively, in the mentioned laser-wound studies, human albumin solder supplemented with transforming growth factor (TGF)-1 only, but not with HB-EGF or bFGF, increased the early postoperative strength of laser-welded wounds (Poppas et al., 1996), even though the superpulsed CO 2 laser enhanced fibroblast replication and appeared to stimulate bFGF and inhibit TGF-1 secretion (Nowak et al., 2000)
Also, studies in rats with injury of the Achilles tendon report a faster rate of healing and recovery
Sterility and endotoxin concerns Most research peptides are not sterile , and powder sterilization is nearly impossible without degrading the peptide
Research consistently shows that lyophilized peptides can remain stable for months or even years
If the water is out of spec, every peptide it touches is compromised regardless of how rigorously those peptides were verified before reconstitution
Some clinical scenarios tilt the balance
