Peptide Reviews

BPC-157 is the most researched healing peptide available, with an impressive preclinical evidence base across multiple organ systems. Its safety profile is excellent and user satisfaction is high. The primary limitation is the lack of large-scale human clinical trials.

TB-500 is a well-tolerated healing peptide with a plausible mechanism (actin regulation, angiogenesis) and good anecdotal support. Its evidence base is less extensive than BPC-157, and it is most commonly used in combination with BPC-157 as the Recovery Stack.

The ipamorelin / CJC-1295 combination is the most popular GH optimization stack for good reason. It produces synergistic pulsatile GH release with an excellent safety profile. The primary limitations are the requirement for daily injection and the lack of large-scale human trials.

Semaglutide is the most evidence-backed weight loss medication in history, with ~15% average weight loss and significant cardiovascular benefits demonstrated in large-scale trials. The primary limitations are cost, GI side effects during titration, and the requirement for ongoing use to maintain results.

GHK-Cu has the best evidence-to-safety ratio of any anti-aging peptide. Its skin evidence is strong, it is exceptionally well-tolerated, and it is available in both topical and injectable forms. The primary limitation is that most evidence is for skin applications rather than systemic anti-aging.
