As of October 2026, the cheapest listing is **R570.00** (R57.00/mg) from [White Rabbit Labs](https://peptidesupermarket.co.za/suppliers/white-rabbit-labs), the average is **R570.00**, and the highest is **R570.00** from White Rabbit Labs. ## Reading the P21 price spread The spread between the cheapest and most expensive P21 listing is about **0%**. A wide spread means it genuinely pays to shop around; a narrow one means the market has settled and most sellers are competitive. The spread bar and order book above update continuously as suppliers change their pricing. ## What moves the P21 price? - **Dosage size** — larger 10mg vials usually carry a lower per-mg cost. - **Lab testing** — independently tested product typically commands a small premium. - **Shipping** — free-delivery thresholds can flip which supplier is truly cheapest once postage is added. - **Discount codes** — checkout codes can move a listing several places up the ranking. ## Tracking P21 prices over time The 30-day chart plots the cheapest, average and highest P21 price each day. Use it to judge whether today's **R570.00** is a genuine low or just the current going rate, and to time your order around the dips. > For in-vitro laboratory research use only.
