“Reconstitute 10mg of BPC-157 in 5ml of BSW solution”
“My BPC-157 protocol: Reconstitute 10mg of BPC-157 in 5ml of BSW solution. Concentration will be 2mg/ml. Administer 0.20ml per injection, which provides 0.4mg of per shot. 1x daily for 20 days.”
Context: A reply to a follower asking how he used it after his widely shared June 2024 ankle sprain post. It describes his own use only. Two years later he wrote (6 May 2026): "If you don't have the bandwidth for extensive testing, you are better off steering away from unregulated peptides."
On safety & evidence
Unregulated peptides
“If you don't have the bandwidth for extensive testing, you are better off steering away from unregulated peptides. The risk profile of research peptides like BPC-157, TB-500, CJC-1295, and ipamorelin is largely unknown.”
Context: Opening of a longer post contrasting grey-market research peptides with approved peptide drugs, whose risk profile is characterised through three trial phases and post-marketing surveillance.
Own use: daily for three months, no measurable effect
Dose

How often
“daily”
How long
“three months”
How taken
“intramuscularly”
“Cerebrolysin Trialed daily 5 mL cerebrolysin injections intramuscularly for cognitive benefits for three months. No effect measured. This does not mean it didn’t help or hurt, we were just unable to identify a biomarker that could inform.”
