Every compound below has the same week-by-week table as its product page and a one-line recommendation. These are research starting points, not medical advice — never step up faster than the table says. All doses are per injection; the calculator tells you the volume to draw for the strength you bought.
Instruction how to inject peptides
Syringes: use a U-100 insulin syringe — 0.3 ml, 30G, 8 mm needle (0.5 ml only if a dose needs more than 0.3 ml). They cost a few euros in any pharmacy or online shop in your country, and Amazon ships them where local shops do not. One needle, one injection.
