Research Peptides FAQ

Everything Australian researchers need to know about peptides — from mechanisms and dosage to reconstitution, legality, and supplier quality.

Recovery & Tissue Repair

What is BPC-157 used for in research?+
BPC-157 is studied for tendon and ligament healing, gastrointestinal repair, and systemic anti-inflammatory effects. It modulates multiple growth factors simultaneously including VEGF, FGF, and EGF. Shop BPC-157
What is the typical research dosage for BPC-157?+
Gut healing: 250-500 mcg twice daily for 4-6 weeks. Soft tissue repair: 200-400 mcg once daily for 2-4 weeks. Systemic recovery: 250 mcg daily for 4-8 weeks. Always follow your institution's approved research protocol.
How should BPC-157 be reconstituted?+
Use 2-3mL sterile bacteriostatic water. Gently swirl — do not shake. 5mg/2mL = 250mcg per 0.1mL. Store at 2-8C and use within 7-14 days. Full reconstitution guide
Is BPC-157 legal in Australia?+
Yes, BPC-157 is legal to purchase for legitimate research purposes in Australia. It is not a scheduled substance when intended for research use only. All Element42 sales are strictly for research — not for human consumption.
How is each batch tested for purity?+
Every batch is sent to an independent lab for HPLC and Mass Spectrometry. COAs confirming 99%+ purity are published on each product page. View BPC-157 COA
What is TB-500's mechanism?+
TB-500 (Thymosin Beta-4) sequesters G-actin to modulate cytoskeletal dynamics, upregulates MMP-2 for ECM remodelling, and promotes angiogenesis via VEGF and KGF. Shop TB-500
What is TB-500 used for in research?+
TB-500 is studied in muscle repair, tendon/ligament healing, cardiac ischaemia models, wound healing, and corneal repair. Loading: 5-20 mg/week divided across 2 injections. Maintenance: 2.5-5 mg every 2 weeks.
Is TB-500 legal in Australia?+
Yes, TB-500 is legal to purchase for legitimate research purposes in Australia. All sales are strictly for laboratory research — not for human or veterinary consumption.
What is GHK-Cu's mechanism?+
GHK-Cu is a naturally occurring copper tripeptide that activates over 300 human genes involved in collagen synthesis, antioxidant defence, tissue repair, and anti-aging. Found naturally in human plasma. Shop Glow blend
How should the Glow blend be reconstituted?+
Add 2mL bacteriostatic water to the 10/10/100mg vial. BPC-157 component: 250-500 mcg. TB-500: 5-10 mg/week. GHK-Cu: 1-3 mg/day. Refrigerate at 2-8C, use within 7-14 days.

Nootropics

What is Semax's mechanism?+
Semax is a synthetic heptapeptide derived from ACTH(4-10) that upregulates BDNF and modulates dopaminergic/serotonergic systems. Intranasal is the standard route at 300-600 mcg, 1-2 times daily. Shop Semax
Has Semax been studied in human trials?+
Yes. Russian clinical trials studied Semax for stroke recovery and cognitive impairment. Intranasal administration (300-600 mcg, 1-2x daily) is standard. Some protocols use up to 1200 mcg/day.
What is Selank's mechanism?+
Selank enhances GABA-A receptor function through an alternative mechanism to benzodiazepines. It modulates serotonin/dopamine turnover and upregulates BDNF. Anxiolytic effects without sedation or withdrawal. Shop Selank
How does Selank differ from benzodiazepines?+
Unlike benzodiazepines (which can cause sedation, tolerance, and withdrawal), Selank-enhanced GABAergic transmission shows anxiolytic effects without sedation, muscle relaxation, cognitive impairment, or withdrawal syndrome in animal models.
Are Semax and Selank legal in Australia?+
Yes. Both Semax and Selank are legal to purchase for legitimate research purposes in Australia. Neither is a scheduled substance when intended for laboratory research use only.

Longevity & Anti-Aging

What is NAD+ used for in longevity research?+
NAD+ is a central coenzyme in cellular metabolism and DNA repair. Research focuses on NAD+ decline with age and its role in mitochondrial function, sirtuin activation, and genomic stability. Shop NAD+
Why does NAD+ decline with age?+
NAD+ levels decline due to increased activity of NAD+-consuming enzymes (PARPs, CD38, SARM1) and reduced biosynthesis — core hallmarks of aging biology affecting mitochondrial function and cellular repair.
How is NAD+ administered in research?+
IV: 250mg-1g over 2-8 hours (max bioavailability). SQ/IM: 50-100mg per dose. NAD+ in solution degrades rapidly use within 24-48 hours. Store lyophilized at -20C for long-term stability.

Metabolic Peptides

What makes Retatrutide different from Tirzepatide?+
Retatrutide is a triple GIP/GLP-1/glucagon agonist. Tirzepatide is a dual GIP/GLP-1 agonist. Retatrutide's glucagon activation drives thermogenesis TRIUMPH-2 showed 24.2% weight reduction at 48 weeks. Shop Retatrutide
Is Retatrutide legal in Australia?+
Yes. Retatrutide is legal for research purposes in Australia and is not a scheduled substance when intended for laboratory use only. Read the full guide: Retatrutide Research Guide
Is Tirzepatide in stock?+
Tirzepatide is currently out of stock. Retatrutide is our in-stock alternative with a broader triple agonist mechanism. Shop Retatrutide
What purity is E42's Retatrutide?+
Our Retatrutide tested at 99.315% purity by Janoshik Analytical (COA dated Jul 2025). Full HPLC and MS results available on the Lab Results page. View product
