Right now the best IGF-1 Long R3 price is **£21.95** from [Cobalt Peptides](https://peptidesupermarket.co.uk/suppliers/cobalt-peptides), based on the 1mg dosage. Across all 54 suppliers we track, the average sits at **£55.15**, while the most expensive listing comes from Adaptog Research. That's a spread of roughly **87%** between the cheapest and dearest — so choosing the right vendor can make a real difference to what you pay. Because we normalise every listing to the same 1mg dosage, the prices above are directly comparable. The cheapest option currently works out at around £21.95/mg, which is the figure worth anchoring on when you weigh up vials of different sizes. ## How we track IGF-1 Long R3 prices We continuously monitor IGF-1 Long R3 listings from 54 verified UK suppliers, recording every price change as it happens. Each price is converted to a per-milligram figure for the 1mg dosage so you're always comparing like for like, never headline numbers that hide a smaller vial. The comparison table updates automatically, and the 30-day chart above shows whether IGF-1 Long R3 is trending cheaper or more expensive — handy for deciding whether to buy now or wait. ## Is the cheapest IGF-1 Long R3 always the best buy? Not always. The lowest sticker price doesn't guarantee the lowest cost per milligram, and a vendor without third-party lab testing may not be the bargain it appears. When we rank value we look beyond price alone at: - **Purity and lab testing** — independent certificates of analysis confirming concentration and identity. - **Stock status** — an unbeatable price is no use if the product is out of stock. - **Delivery speed and cost** — free-shipping thresholds can flip which supplier is genuinely cheapest once postage is added. - **Reputation** — established vendors with verified reviews carry less risk. ## Tips for getting the best IGF-1 Long R3 price - **Compare the per-mg cost**, not just the headline price — larger 1mg vials are often better value than several small ones. - **Use discount codes** — some suppliers offer an extra percentage off at checkout, which can beat a lower sticker price elsewhere. - **Buy when the trend dips** — the 30-day chart shows the cheapest, average and highest price each day so you can time your order. - **Check the total cost** — factor in shipping and any free-delivery threshold before deciding. ## How much should you pay for IGF-1 Long R3? As a rule of thumb, expect to pay around **£55.15** for the 1mg dosage, with the keenest UK pricing starting at **£21.95**. Anything close to **£172.50** is at the top of the current range — worth it only if it buys you faster delivery, a stronger guarantee, or verified testing you can't get cheaper elsewhere. > All peptides listed are for in-vitro laboratory research only.
