A Gold Bottle Cap starts multi-stat Hyper Training for one eligible Pokémon. Niantic says Bottle Caps come from various in-game research tasks, but its help page does not name a currently available task or event. Use a cap promptly: both the item and an active training period are time-limited.
What a Gold Bottle Cap does
Niantic describes Gold Bottle Caps as items that enter a Pokémon into Hyper Training for multiple stats. You choose stat goals, then complete the tasks assigned to those stats. Each completed task adds one point to its assigned stat; the number of points in your plan determines the number of tasks. Only one task per stat can be progressed at a time.
You can adjust a stat’s goal within its current and maximum values while planning, but completed increases cannot be reversed. Consider the target Pokémon’s intended use before confirming your plan.
Who can be Hyper Trained
- The Pokémon must be at least Good Buddy.
- It must be your active buddy while you make progress on Hyper Training tasks.
- Shadow Pokémon and Pokémon already rated four stars are not eligible.
Gold Bottle Cap vs. Silver Bottle Cap
| Item | Stats per use | Using another cap |
|---|---|---|
| Gold Bottle Cap | Multiple stats in one Hyper Training plan. | Not stated by Niantic’s help page. |
| Silver Bottle Cap | One stat. | Niantic says multiple Silver Bottle Caps can be used on a Pokémon after it has finished Hyper Training. |

Niantic lists three ways to begin. Each route leads to setting the stat goals and starting the associated tasks:

How to get Gold Bottle Caps
The documented route is to complete in-game research tasks that award Bottle Caps. Niantic’s help page describes rewards from various research tasks, but does not identify a live task, event, schedule, region, or guarantee that one is currently available. Check the rewards shown in the game’s current research rather than relying on an old event list.
Time limits and important consequences
Watch the item’s expiry
A Bottle Cap remains in the Item Bag for a limited time. Niantic advises using it when it appears under “Expiring Soon.”

Complete training within its active period
Hyper Training itself is also time-limited and can last up to one year. Keep the Pokémon as your buddy while progressing, and make sure you can complete the planned tasks during the available period.
Check CP before confirming
Improving stats raises the Pokémon’s CP. If you plan to use it in GO Battle League, check the applicable league CP limit first. The game warns before confirmation when a plan would exceed certain limits.
