Context: From his “Recover Like Wolverine” stack. He calls these “simply general guidelines”, recommends starting “on the lower end”, and writes that he is not a doctor. He notes WADA has banned BPC-157 since 1 January 2022.
On safety & evidence
Cancer & safety
“I'm not going to say that's ironclad and that we don't still have a need for long-term human clinical research on the association between any peptide including BPC 157 and cancer. However, it's very safe, it's very simple and I'm personally comfortable using it.”

Context: From a listener Q&A clip ("can BPC-157 feed polyp growth in the colon?") included in this compilation; the date shown is the compilation's upload date. Right after this he says that if a colonoscopy found polyps he would restrict anything anabolic, naming BPC-157. This is his personal view, not a clinical finding.
“it’s best to follow your practitioner or manufacturer’s suggestions”

However, here is what I’ve used: 5-2.5 mg, 2–3x/week; OR 25mL of 3000mcg/mL solution daily for a 20-day cycle. Administration Route: Subcutaneous or intramuscular injection”

“LL-37, an anti-microbial peptide, helped my gut recover from a nasty bout of giardia thanks to a water filter snafu during a wilderness survival course.”

Context: No dose given.
Warning: die-off reaction
“Warning: If you have SIBO, the die-off and Jarisch-Herxheimer Reaction from LL-37 can be uncomfortable and may involve flu-like symptoms and diarrhea for up to two weeks.”

Context: Same article. He goes on to say many people then see their SIBO symptoms resolve; we have not found trial evidence for that.
“Proper timing, especially around meals, is crucial for peptides like GHK-Cu, KPV, and TB4. Consuming high-protein meals can reduce the effectiveness of most peptides, so scheduling their use strategically ensures optimal absorption and results.”

“This is why GHRP-6 should be administered on an empty stomach (no food should be consumed for 15-20 minutes post-injection if maximum GH release is desired. In addition when using GHRP-6 for GH release, the average dosing range is between 100-150 mcg per injection and dosing frequency is between 1-4X per day.”

Context: From his 2016 growth-hormone stack article. The opening bracket is not closed in the original. He adds that GHRP-6 “should be combined with a GHRH” for maximal GH release.
On safety & evidence
Side effects of GHRPs
“When used in excessive quantities or excessive frequencies, or stacked incorrectly with the other compounds you’ll learn about in this article, all GHRP’s also share a few common negative side effects: specifically water retention, excessive sleepiness, tightness or carpel tunnel-like symptoms in the wrist/hand, numbness and tingling in the extremities, and a decrease in insulin sensitivity.”

Context: In the same article he writes that “compared to GHRP-2, GHRP-6 tends to cause a huge increase in hunger.”
“As mentioned earlier, I do not use melatonin unless I’m traveling, in which case 1-3mg 30-60 minutes prior to bed can be useful for re-booting the circadian rhythm upon arriving at the final destination (1). I’d discourage using it until that point (e.g. on the airplane).”

Context: Own use, from a 2013 article. Later articles on his site describe much higher doses.
On safety & evidence
Short-term use only
“I’m OK with using melatonin at a dosage of 1-3mg while you’re traveling, but I don’t recommend using it for long periods of time, since you don’t want to shut down your body’s natural ability to produce melatonin (1).”
Read the sourceHow To Get Better Sleep Part 2 (bengreenfieldlife.com) · 3 Jul 2013
Context: His view in 2013. The research reviews listed below found no clear evidence that short-term use stops the body making melatonin; long-term data are limited.

Context: From a list of stacks he says he recommends. Just before the list he writes that he has discussed his favourite stacks “with Jay Campbell” and does not want to reinvent the wheel; the wording matches Jay Campbell’s 2022 own-use article almost exactly, so this is best read as Greenfield endorsing the same protocol rather than as a separate one.
