# NPCRIZ Peptide Complexes (PK liquid drops) NPCRIZ Peptide Complexes (PK series) — liquid peptide formulations in 10 ml bottles. These are the first-generation NPCRIZ peptide products, developed before the capsule form. To this day, PK drops remain a preferred form among long-term NPCRIZ users due to their easily adjustable dose. What makes PK drops distinct: Universal dosing — drop count can be adjusted by need (typically 3–6 drops twice daily). Family-friendly — the same bottle suits different doses (adults vs. older persons). 19 complexes for the whole body — PK-1 through PK-19, each for a separate system. Fast absorption — dropped under the tongue or added to warm water. Usage: 3–6 drops twice daily, dropped under the tongue and held for 1–2 minutes before swallowing, or added to a small amount of water. Course duration: 30 days. Range at gavau.lt: all 19 NPCRIZ Peptide Complexes — from PK-1 (heart) to PK-19 (male reproductive health). Bottle: 10 ml with dropper. 📖 Learn more NPCRIZ Peptide Guide arrow_forward About the institute, peptides, delivery forms and how to choose the right product — all in one place.
