What did @tiana.prime actually say?
@tiana.prime walked viewers through a self-administered subcutaneous injection stack: "2.5 MG of GHK CU," "10 units of MT2," and "10 units or 1 MG" of what she calls "redder" (almost certainly BPC-157, based on her dosing pattern and the twice-weekly schedule she describes). She notes she diluted her GHK-Cu with a significant volume of bacteriostatic water. She takes BPC-157 "twice a week" at "half of a dose at each time." There's no mention of a prescribing physician, a clinical indication, or lab monitoring. The video is essentially a how-I-inject tutorial for three unapproved, unregulated peptides, served to 10,000+ viewers who may have no medical supervision at all.
Does the science back this up?
The honest answer is: partially, for some of these compounds, in animal models and early human data. Not across the board, and not at the doses she's describing without clinical oversight.
GHK-Cu (copper peptide) has the strongest legitimate research base of the three here. Studies including Pickart and Margolina (2018, Cosmetics) document its role in wound healing, collagen synthesis, and anti-inflammatory signaling. Most of that evidence, however, is topical or in vitro. Systemic injectable use in humans is not well-studied.
MT-II (Melanotan II) is a non-selective melanocortin receptor agonist. It does cause skin tanning and has documented effects on sexual arousal, which is likely why it's used recreationally. But it carries real cardiovascular and dermatological risks. Wessells et al. (2000, Urology) showed modest effects on erectile function, but side effects including nausea, facial flushing, and spontaneous erections were common. It is not FDA-approved for any indication.
BPC-157 (Body Protection Compound 157) has intriguing animal data on gut healing and tendon repair (Sikiric et al., 2018, Current Pharmaceutical Design), but zero completed randomized controlled trials in humans. Calling it proven at this stage is premature.
What did they get wrong (or right)?
Credit where it's due: diluting peptides with bacteriostatic water is the correct reconstitution method, and cleaning vial tops before drawing is basic sterile technique. She's doing the mechanical steps right.
What she got wrong, or at least left dangerously incomplete: there is no context for why she's taking these compounds, no mention of medical supervision, and no disclosure of the real risk profile of MT-II. Melanotan II has been linked to melanocytic nevi changes (moles that can appear or darken), blood pressure spikes, and nausea severe enough to be disabling for some users. A 2009 case report in the BMJ (Coelho et al.) documented a changing melanocytic lesion in a young man who used MT-II. Showing injection technique without this context is irresponsible, regardless of how clean her needle drawing is.
The dose she describes for BPC-157 (1 mg, twice weekly) is well above what most peptide-prescribing clinicians use. This is not a recommendation either way, but the absence of any discussion of dosing rationale is a gap that matters.
What should you actually know?
None of these three peptides are FDA-approved drugs. They are sold as research chemicals in the U.S. and are not legal to market for human use outside of a licensed compounding pharmacy operating under a valid prescription. That regulatory reality matters because it means no quality control standard applies to what you're actually injecting.
MT-II in particular carries a risk profile that casual TikTok content almost never addresses. Beyond cosmetic tanning, it acts on brain receptors in ways that affect blood pressure, appetite, and sexual function simultaneously. The "10 units" framing in the video tells viewers nothing about the concentration of her solution, which determines actual dose entirely.
GHK-Cu at 2.5 mg injectable is unusual. Most studied applications are topical. If someone is prescribing injectable GHK-Cu systemically, that's an off-label use with limited safety data in humans. That doesn't make it automatically dangerous, but it deserves acknowledgment.
If you're curious about peptide therapy, that conversation belongs with a licensed clinician who can evaluate your actual health status, not a TikTok comment section.
