With 1 UK suppliers in our index and an average price of **£31.50**, the gap between the best and worst deal is roughly **0%**, so it genuinely pays to shop around rather than buy from the first vendor you find. ## How much cheaper is the best deal? The cheapest TB4 listing (£31.50) sits well below the average of £31.50, and the most expensive vendor, RP Peptides, charges up to £31.50. Buying from the cheapest verified supplier rather than the dearest could save you the better part of **0%** on every vial — money better spent on more product or proper storage. ## Is the cheapest TB4 always the best buy? Not necessarily. The lowest sticker price doesn't always mean the lowest cost per milligram, and an unverified supplier may skip third-party lab testing to keep prices down. Before you check out, weigh the headline price against: - **Cost per mg** for the 5mg dosage, not just the price of the vial. - **Lab testing** — a certificate of analysis confirming purity and concentration. - **Stock and delivery** — in-stock items with fast, affordable UK shipping. - **Discount codes** — an extra percentage off at checkout can make a mid-priced vendor the cheapest overall. ## Track TB4 prices over time Our 30-day trend chart shows the cheapest, average and highest TB4 prices day by day, so you can spot whether prices are rising or falling before you commit. If the cheapest line is trending down, it can pay to wait; if it's climbing, locking in today's £31.50 may be the smarter move. ## Frequently asked questions **Who sells the cheapest TB4 in the UK?** Right now it's RP Peptides at £31.50, though our table updates continuously as suppliers change their pricing. **Why are some TB4 prices so much higher?** Larger dosages, branded packaging, faster shipping and independent lab testing all push prices up. Always compare the per-mg cost to see past the headline figure. > For in-vitro laboratory research use only.
