Transcript
- 0:00Unapproved peptides could reach temporary sale while treatment claims are still not fully safety tested. This is Peptides Weekly, episode 4. Education and evidence, never-dosing advice. Political wire quotes the Washington Post on a drafting process, which is policy reporting rather than a patient trial. The paper's account says compounding pharmacies could hand out some of those peptides as marketed treatments and as wellness products.
- 0:26effects.
- 0:27Federal health officials are still writing the regulations around them.
- 0:31On October 1st, this show was tracking compounding rules, and the new piece is that temporary
- 0:37sale draft for products the headline still calls unapproved.
- 0:41Stock Twits reported an FDA advisory panel backed four peptides, a panel action rather
- 0:47than a published patient study.
- 0:49That item also tied the backing to an overnight rise in hymns' shares and a short bit by
- 0:55Martin Shkreli. Medical economics, the same day, said the FDA would convene an expert panel
- 1:01on wider peptide access. Those reports describe meetings, backing, and a share move, not a measured
- 1:08health outcome. The ASCO post reported a link between GLP1 receptor agonist use and lower colorectal
- 1:16cancer risk among people with inflammatory bowel disease. The Sacramento Bee and the Raleigh News
- 1:22an observer, both ran consumer pieces on oral peptide strips.
- 1:27The B says the strips promised needle-free delivery and puts the FDA and researcher view as
- 1:32the question in play.
- 1:34The news and observer describes dissolving films and asks how the strips work.
- 1:39In the text here, neither piece is a human efficacy measurement.
- 1:43Food Navigator reported that weight regained after GLP1 treatment could be mitigated by
- 1:49diet.
- 1:49it.
- 1:50That is a possibility stated in a headline, not a randomized trial result with a number
- 1:55attached.
- 1:56This week's spotlight is collagen peptides taken by mouth, studied as supplements and
- 2:01in one paper as a neutrophosimetic ingredient, not as a named approved drug.
- 2:07A 2015 cosmetic dermatology paper says earlier preclinical work suggested these fragments
- 2:13can support the skin barrier, prompt collagen and hyaluronic acid synthesis, and encourage
- 2:19fibroblasts to grow and move. In human skin
- 2:23plants, an X vivo setup, the peptides induced collagen and glycosaminoglycan
- 2:28production. That is a tissue finding, not a map of digestion in a living person.
- 2:34The same paper reports two placebo-controlled human trials in which oral
- 2:38supplementation raised skin hydration after eight weeks by corneometry.
- 2:44Dermal collagen density rows and network fragmentation fell after four weeks on
- 2:49ultrasound and reflectance confocal microscopy, and both structural changes were still there
- 2:55at 12 weeks. A separate randomized placebo-controlled trial enrolled Korean adults aged 19 to 60
- 3:02with mild to moderate hair damage and no alopecia. After 24 weeks of a low molecular weight collagen
- 3:09peptide called GT, gloss improved against placebo on a gloss meter and on scanning electron microscopy.
- 3:16Elasticity improved too, judged by tensile strength and hair diameter, and scalp elasticity
- 3:23rose in the treated group.
- 3:25Participants also rated gloss, elasticity, thickness, texture, fullness, and appearance
- 3:31as better.
- 3:32No treatment-related adverse events were observed, and the authors called the course
- 3:36safe and effective for hair condition in that group.
- 3:40The abstract notes earlier preclinical work in which low molecular weight fish collagen
- 3:45peptides promoted hair regrowth through proliferative signals and less inhibitory signaling,
- 3:51and it says clinical efficacy for hair damage had not been clearly shown before this trial.
- 3:56This human study measured damage and shine, not regrowth in alopecia.
- 4:01A pilot randomized double-blind trial followed 22 premenopausal women, 18-35, who ran at least
- 4:0935 miles a week. For four weeks they took collagen peptides or an isocholoric
- 4:14maltodextreme placebo, with labs in the early follicular phase. P1NP, a bone
- 4:21formation marker, showed a group by time interaction at P equals 0.04. It rose
- 4:27on collagen and did not change on placebo. CTX1, a breakdown marker, had no
- 4:34significant interaction, P equals 0.13.
- 4:38IL-6 showed a significant interaction at P equals 0.03.
- 4:43The results text both reports a significant S-rankel interaction
- 4:47at P equals 0.046, and later says no significant interaction
- 4:52for S-rankel, osteoprategorin, or their ratio,
- 4:56so that osteoclast signal is not cleanly established.
- 5:00The discussion still says the short course raised a formation marker, shifted osteoclast-related
- 5:06signaling, and lowered IL-6, and it asks for larger trials with structural bone outcomes.
- 5:13Another randomized double-blind trial followed 53 men with sarcopenia, mean age 72.2 years,
- 5:20standard deviation 4.68.
- 5:23All of them did 12 weeks of guided resistance training, three sessions a week, plus either
- 5:28collagen peptides or a silica placebo.
- 5:32Finisher as a whole gained fat-free mass, bone mass, quadricep strength, and sensory motor
- 5:38control, and lost fat, each at p less than 0.01.
- 5:43The collagen arm moved further, fat-free mass up 4.2 kg versus 2.9.
- 5:49Strength up 16.5 Newton meters versus 7.3.
- 5:54Fat mass down 5.4 kg versus 3.5.
- 5:57each comparison P less than 0.05. That extra change belongs to training plus
- 6:04supplement, not to the peptide by itself. Across this set, fracture prevention is
- 6:09not shown, alopecia regrowth is not shown, and a blood marker is not a clinical
- 6:14bone outcome. Only the hair trial states a safety result, and none of these
- 6:19abstracts test whether a retail bottle matches the study material. One thing
- 6:24Being worth knowing is that a cancer risk link for GLP1 drugs in inflammatory bowel disease
- 6:30does not mean those drugs have been shown to prevent cancer.
- 6:34Another is that the collagen human trials measure skin structure, hair condition, bone markers,
- 6:40and training-related body composition, which is not the same as treating a disease.
- 6:45A third is that temporary sale drafts and advisory panel backing are about access and process,
- 6:51not prove those peptides work in people. That's peptides weekly. This show is
