Had several patients ask me about these peptides that are deemed as "for research only" and "not for human use". They saw videos on TikTok or had a friend who recommended it to them. Spent half an hour to explain the rigorous testing process and protocols that must be adhered to when pharmaceutical companies conduct clinical trials to apply for FDA approval. I am so grateful to have the time in direct primary care to educate patients on the risks associated with any medical decision, and truly have a partnership with my patients where they feel comfortable reaching out to me about these types of things.
These peptides have not undergone rigorous clinical trials to determine safety and hence have the disclaimer as being "not for human use". This alone should tell you a lot about the risk involved with these drugs.
You’re injecting what now?!
We’ve been flooded with questions about injectable peptides, so here’s the bottom line: I would not inject these into myself or anyone I care about.
🚨Note: This is about non–FDA-approved peptides sold for “wellness,” muscle gain, and anti-aging — NOT legitimate peptide medications like insulin or GLP-1 drugs (Ozempic, Wegovy).
Most popular peptides (BPC-157, TB-500, CJC-1295, etc.) have little to no meaningful human data. A few have tiny early studies, but none have the long-term controlled trials needed to establish safety. Nearly everything comes from rodent research — which rarely predicts human outcomes. 🐀
🤔Major unknowns:
➡️Growth-stimulating peptides could, in theory, also stimulate cancer growth. We don’t know.
➡️Many alter hormonal pathways (like growth hormone/IGF-1), but the long-term effects in healthy people are unknown.
➡️People “stacking” multiple peptides are doing something never studied in humans.
➡️Regulators have warned of immune reactions, contamination, and unpredictable side effects — but we don’t actually know the true risk.
⚠️Quality concerns:
Unlike FDA-approved drugs, these products are often made or sold with no standardization:
➡️Purity and dosing are not guaranteed
➡️Batch-to-batch consistency is questionable
➡️Improper storage can create harmful breakdown products
➡️Several peptides are banned in sports as unapproved performance enhancers
Many companies sell peptides as “research chemicals” or “not for human use” while implying exactly how to inject them. This is a regulatory loophole that means:
⛔️No safety testing
⛔️No required monitoring
⛔️No accountability if someone is harmed
And yet people are paying hundreds to thousands of dollars a month for substances with essentially unknown risk profiles.
Injecting unapproved peptides means betting your health on animal data, marketing claims, and hope. The benefits remain theoretical. The risks are unclear and could be significant.
Influencer marketing is powerful, but it shouldn’t replace evidence.
