Either way, check for air bubbles by gently tapping the syringe and pushing the plunger slightly to expel any air
Then begin retatrutide at the 2mg starting dose, not at a dose you estimate is "equivalent" to your previous protocol
Croatian researchers isolated the full, larger peptide BPC in 1998 from gastric juices and found the 15 amino acid sequence, BPC-157 to be the active part responsible for its clinical effects (the story of how it was discovered is fascinating, but that is a conversation for a different day if there is enough interest, let me know below)
If you must store peptides at room temperature, minimize exposure to air, moisture, and light by using sealed containers with desiccants and storing them in a dark place
Lyophilized BPC-157 remains stable for 24+ months when stored at -20C or below
