Common questions
521What if the COA shows 97% purity instead of the advertised 98%?
Contact the supplier immediately and request a replacement batch or refund. Real Peptides guarantees ≥98% purity by HPLC. Batches testing below that threshold are not released to customers. If you receive a vial with lower-than-specified purity, it indicates either mislabeling, degradation during shipping, or documentation error. Legitimate suppliers replace non-conforming batches at no cost because maintaining advertised specifications is their contractual obligation. If the supplier resists replacement, that's a red flag indicating systemic quality control failures.

Mild redness (1–2 cm diameter) that resolves within 24 hours is a normal immune response to subcutaneous peptide injection. It reflects localised cytokine release and is not a contraindication to continued use. Apply a cold compress for 10 minutes post-injection to reduce inflammation. If redness exceeds 3 cm, persists beyond 48 hours, or is accompanied by warmth and tenderness, this suggests either incorrect injection technique (injected too shallow into the dermis rather than subcutaneous fat) or localised infection. Rotate injection sites with every dose and ensure proper antiseptic technique. Wipe the injection site with 70% isopropyl alcohol and allow it to dry completely before inserting the needle.

Discard it immediately. Cloudiness indicates protein aggregation or bacterial contamination, both of which render the peptide ineffective and potentially unsafe. ARA-290 in solution should remain clear and colourless throughout the 28-day refrigerated storage window. If cloudiness appears, the most likely causes are: (1) temperature excursion above 8°C during storage, (2) contamination introduced during repeated vial access, or (3) use of non-sterile bacteriostatic water. Do not attempt to 'clarify' the solution by warming or filtering. Aggregated proteins cannot be reversed.

Administer the missed dose as soon as you remember if fewer than 12 hours have passed since the scheduled time, then resume the regular schedule. If more than 12 hours have passed, skip the missed dose entirely and continue with the next scheduled administration. Do not double-dose. Missing 1–2 doses across an 8-week protocol is unlikely to significantly impact efficacy, but missing more than 5 doses may require extending the protocol duration to compensate for the gap in sustained receptor activation.

For extreme time shifts (>8 hours), the direction of adaptation becomes ambiguous. Your body may adapt "backwards" (e.g., treating a 10-hour eastward shift as a 14-hour westward shift). In these cases, calculate which direction requires fewer adjustment days. A traveler going from San Francisco to Tokyo (+17 hours) might adapt faster by delaying their clock 7 hours westward rather than advancing it 17 hours eastward. Use melatonin and light exposure to support whichever direction minimises total phase shift. Circadian rhythm researchers call this the "forbidden zone" of travel.

Discard the vial. VIP peptide degrades rapidly at room temperature. 8–12 hours at 20–25°C reduces bioactivity by 40–60% through peptidyl bond hydrolysis and oxidative degradation. The solution may appear clear and unchanged, but HPLC assay would reveal significant breakdown into inactive peptide fragments. Using degraded VIP wastes the dose (no therapeutic effect) and introduces measurement error into research data. Temperature-compromised peptides cannot be salvaged through re-refrigeration.

Contact the supplier immediately and request the batch-specific analytical report. Legitimate suppliers maintain searchable databases of lot numbers cross-referenced to COAs. If they can't provide the matching document within 24 hours, the traceability claim is questionable. Real Peptides posts COAs directly on product pages with lot numbers visible before purchase, and our support team can pull archived reports for any shipped batch within minutes. A supplier who assigns lot numbers but doesn't maintain accessible analytical records is performing security theater, not quality assurance.
Source: realpeptides.co ↗528What If the Supplier Provides a CoA but Refuses to Share Mass Spectrometry Data?
Request the mass spec report directly. Any supplier who refuses is selling unverified product. HPLC certificates confirm purity but do not verify which peptide is present. Mass spectrometry is the only method that definitively confirms the Glu-Asp-Arg amino acid sequence. Suppliers who synthesise incorrect peptides can still produce high-purity samples that pass HPLC testing. The molecular ion peak at 329.34 g/mol is the signature of authentic Pinealon. Deviations indicate sequence errors that render the peptide biologically inert.
Source: realpeptides.co ↗529What If the COA Shows 92% Purity Instead of 98%?
Don't use it for dose-dependent studies. A 6% purity gap means 120mcg of unknown compounds per 2mg vial. Those impurities could be truncated DSIP sequences, deletion analogues from incomplete synthesis, or residual coupling reagents. For preliminary screening or non-quantitative assays, 92% might be acceptable if the impurity profile is documented. For any work requiring reproducible dosing or publication-quality data, order from a supplier that consistently delivers ≥98%.
Source: realpeptides.co ↗530What If Observable Effects Diminish After Two Weeks of Daily Dosing?
This suggests receptor desensitization. A documented phenomenon with chronic DSIP administration. The solution used in several published protocols: switch to a 5-days-on / 2-days-off schedule. The two-day break allows GABAergic receptors to upregulate without fully resetting the protocol. Alternatively, some researchers reduce the dose to 75–100 mcg after 14 days rather than discontinuing entirely. Our team has found that maintaining a dosing journal tracking sleep latency and subjective sleep quality helps identify the exact point where efficacy begins to decline.
Source: realpeptides.co ↗531What If the Reconstituted Solution Appears Cloudy After Mixing?
Discard the vial immediately. Cloudiness indicates protein aggregation where peptide molecules have clumped together, losing their functional tertiary structure. This happens when reconstitution occurs above 10°C, when the vial is shaken rather than gently swirled, or when the peptide powder was exposed to temperature excursions during shipping. Aggregated Dihexa cannot bind to HGF receptors with the same affinity, rendering the dose ineffective. At Real Peptides, we ship all lyophilized compounds with cold packs and temperature monitors, but once the package arrives, storage discipline becomes the researcher's responsibility. Room temperature exposure for more than 4 hours before reconstitution increases aggregation risk by approximately 60%.

Avoid taking melatonin during the flight unless the flight departs within 2 hours of your destination bedtime and you can sleep for at least 4 hours straight. Melatonin taken during daytime hours at your origin timezone. Especially on westward flights. Can anchor your circadian rhythm to the wrong phase and extend adaptation time. If you take it to "help you sleep" on a daytime departure, you're dosing during your circadian wake-promotion window, which produces minimal sedation and risks mistiming the phase-shift effect. The better approach: use an eye mask and earplugs for sleep, save the melatonin for the destination bedtime.
Source: realpeptides.co ↗533What If the Vial Arrived at Room Temperature Instead of Refrigerated?
Lyophilized ARA-290 can tolerate short-term ambient temperature exposure (24–48 hours at 20–25°C) without complete degradation, but extended room-temperature transit accelerates oxidative breakdown. If the package lacks cold packs or insulation and shipping took longer than 48 hours, request a replacement. Once reconstituted, peptides degraded during shipping show incomplete dissolution or pH shifts outside the 5.0–6.5 range. Real Peptides ships all peptides with temperature-controlled packaging to prevent this exact scenario.
Source: realpeptides.co ↗534What If the Peptide Dissolves But Leaves a Faint Cloudiness?
Discard the vial and request a replacement with full batch documentation. Persistent cloudiness after complete dissolution indicates protein aggregation from improper lyophilization or cold-chain breaks during shipping. Aggregated peptides exhibit reduced receptor-binding affinity and introduce particulate contamination risk in research protocols. Authentic ARA-290 from Real Peptides produces crystal-clear solutions. Any deviation warrants re-sourcing.
Source: realpeptides.co ↗535What if I receive DSIP that was shipped without cold packs or the package feels warm on arrival?
Do not use the peptide—contact the supplier immediately for replacement. Lyophilised DSIP exposed to temperatures above 25°C for more than 12 hours undergoes irreversible oxidative degradation of the tryptophan residue, which eliminates the peptide's activity without changing its appearance. There is no home test for peptide potency loss from temperature excursion—HPLC analysis is required to confirm degradation, and by the time you discover the peptide doesn't work in your research protocol, weeks of experimental time are lost. Real Peptides replaces any shipment that arrives without intact cold packs or with temperature monitors showing excursions above safe storage range.
Source: realpeptides.co ↗536What If Reconstituted Pinealon Produces a Cloudy Solution?
Discard the vial and document the batch number. Cloudiness after reconstitution indicates either incorrect synthesis (wrong amino acid sequence affecting solubility) or contamination with non-peptide fillers. Authentic Pinealon dissolves into a clear, colourless solution. Any turbidity means the product is not research-grade. Contact the supplier with photos and batch documentation. Reputable suppliers replace compromised batches without question. Suppliers who refuse replacement or claim cloudiness is normal are selling substandard product. We've seen research teams waste weeks on protocols using mislabelled peptides that appeared fine visually but produced no biological effect because the amino acid sequence was incorrect from synthesis.
Source: realpeptides.co ↗537What If I Miss Two or Three Doses in a Single Day?
Resume your regular schedule at the next planned dose. Do not double-dose to compensate. VIP's half-life is measured in minutes, so administering a double dose creates a brief spike followed by the same trough you were trying to avoid. Missing occasional doses has minimal impact on overall treatment outcomes, but missing more than 30% of doses over a week reduces efficacy measurably.
Source: realpeptides.co ↗538What If You're Designing a Study and Need to Convert a Published Rodent Dose to Human Equivalent?
Use the FDA allometric formula: multiply the rodent mg/kg dose by 0.162 (the rat-to-human conversion factor). A 3mg/kg rat dose becomes 0.486mg/kg in humans, or approximately 34mg for a 70kg person. This is your starting point. Not the final dose. Adjust for administration frequency based on the peptide's half-life: SS-31's 3.2-hour human half-life means once-daily dosing produces trough plasma levels near zero by 18–20 hours post-injection, which may not sustain mitochondrial protection. Consider twice-daily administration at half the calculated daily dose to maintain more consistent plasma levels.
Source: realpeptides.co ↗539What if no COA is provided with my peptide order?
Request the batch-specific COA directly from the supplier. Credible providers maintain searchable databases where customers can retrieve documentation using the batch number printed on the vial label. If the supplier cannot provide a COA matching your specific batch, do not use the peptide in critical research. The absence of verifiable third-party testing means you have no confirmation of molecular identity, purity, or sterility. Real Peptides includes QR codes on packaging that link directly to the corresponding batch COA, eliminating documentation retrieval barriers.
Source: realpeptides.co ↗540What If I Start at 5mg and Don't Notice Cognitive Changes?
Reduce the dose rather than increasing it. Higher doses don't overcome non-responsiveness. They increase systemic exposure without additional CNS benefit once receptors are saturated. Non-responsiveness typically indicates one of three issues: the peptide has degraded (common if stored improperly above 4°C), baseline synaptic density is already optimal (meaning Dihexa has little substrate to act on), or co-factors required for synaptogenesis (adequate sleep, dietary choline for acetylcholine synthesis, omega-3 fatty acids for membrane remodeling) are insufficient. A two-week washout followed by 0.5–1mg dosing with optimized sleep and nutrition often produces clearer subjective effects than dose escalation.
