Pharmacom Labs bottle their boldenone at 300 mg/ml in a 10 ml vial. The lab built its name on batch-level traceability — each product carries a code tied to the batch it came from — and Pharma Bold is one of the older items in that range.
The compound is boldenone undecylenate: an oil-soluble anabolic androgenic steroid, given intramuscularly, distinguished from testosterone by an added double bond that blunts how readily it converts to oestrogen. Its undecylenate ester is among the longest attached to any injectable steroid, so it clears the body over a notably extended period.
