NOTHING TO WORRY HERE.
Vitamin D toxicity is extremely rare and will not occur if you take 60000 once a week for few weeks.
Also there is no risk of calcification , as vitamin D mainly just absorbs Ca from the intestine , but there are other payers involved in deciding wjat to do with that
calcium. Namely phosphorus and hormone PTH.
Next Steps
Do not worry and try not take any further supplemts without consultation
