Recently, it was shown that the R273H mutant induces 5-FU resistance in colorectal cancer through the downregulation of the proapoptotic protein PUMA
People are getting B12 injections to gain strength, lose weight, and improve their brain functioninga few benefits of vitamin B12
It is commonly used in research and clinical settings to stimulate the release of growth hormone (GH) from the pituitary gland
The interaction effects between the nutritional state and L-carnitine were observed in the whole fish protein content and the mRNA levels of PEPT1 in the muscle (Supplemental Table 5)
What strength do you supply

Problem: Powder won't dissolve completely Causes: Water too cold Not enough time Damaged peptide Solutions: Let sit for 5-10 minutes undisturbed Gently swirl (don't shake) Warm hands around vial (body heat helps) If still not dissolving after 15 minutes, peptide may be degraded Problem: Solution is cloudy or has particles Causes: Contamination Degraded peptide Improper storage before reconstitution Solutions: Do not use cloudy solution Discard the vial Contact vendor for replacement Never inject cloudy peptides Problem: Can't draw liquid from vial Causes: Vacuum in vial Needle blocked Solutions: Inject air into vial before drawing (equal amount to what you're withdrawing) Make sure needle tip is below liquid level Use fresh needle if current one is blocked Problem: Injection site reactions Causes: Injecting too fast Not rotating sites Contaminated peptide Solutions: Inject slower (10 seconds minimum) Rotate sites minimum 1 inch apart Check for cloudiness before injection If reactions persist, discard vial Problem: Uncertain about concentration Causes: Forgot to label vial Added wrong amount of water Mixed up multiple vials Solutions: Always label immediately after reconstitution Use our peptide reconstitution calculator and write exact concentration on vial When uncertain, discard and start fresh (better safe than wrong dose) Reconstitution for specific peptides Quick reference for common peptides
