These guides explain the basics, where the evidence gets thin, how capsule safety works, and why route matters.
Peptide Therapy: What It Is, How It Works & What to Expect
Peptide therapy explained: what peptides actually are, how they signal in the body, which classes have real evidence, and where the hype outpaces the science.
Peptides for Recovery: Where the Evidence Gets Thin
BPC-157, TB-500, and GHK-Cu are marketed for faster recovery, but most evidence is preclinical or anecdotal. An honest look at what the research supports, the research-only regulatory status, WADA bans, and the safety unknowns.
Are Peptide Capsules Safe? Side Effects & Risks Explained
Are peptide capsules safe? The real risks: stomach acid degradation, GI tolerance, vendor purity, contamination — and how they compare to injectable peptides.
Peptide Capsules vs Injectable: Which Actually Works Better?
Peptide capsules vs injectable: the answer is peptide-specific. Which peptides survive oral delivery (BPC-157, MK-677) and which are useless in capsule form.
