Frequently Asked Questions

Peptides are short-chain amino acids that signal the body to perform specific functions. Most fall into a few categories: fat loss and metabolism (Retatrutide, MOTS-C), recovery and healing (BPC-157, TB-500), skin, hair and anti-aging (GHK-Cu), energy and cellular support (NAD+, Epitalon), and cognitive support (Semax, Selank). Most researchers choose based on a single primary goal, then build from there.
Start with your primary outcome. For fat loss, Retatrutide is the most in-demand compound. For injury and recovery, BPC-157 or the BPC+TB-500 stack. For skin and hair, GHK-Cu. For energy and burnout, NAD+. For focus and calm, Semax or Selank. Keep it simple -one goal, one or two compounds, consistency above all else.
Yes. Peptides are supplied as lyophilized (freeze-dried) powder and need to be mixed with bacteriostatic water before use. Add BAC water to the vial, let it dissolve gently -do not shake aggressively -then store in the fridge. Most peptides remain stable for 4–6 weeks once reconstituted when refrigerated.
It depends on the compound. Fat loss and appetite suppression from Retatrutide can be noticeable within days to weeks. Recovery compounds like BPC-157 and TB-500 often show results within 1–2 weeks. Skin and hair improvements from GHK-Cu typically take 2–6+ weeks. NAD+ and cognitive peptides like Semax tend to be fast-acting. Consistency matters more than anything.
Order before 2pm AEST and your peptides dispatch the same business day via AusPost Express. Most customers in Sydney, Melbourne, Brisbane, Perth and Adelaide receive within 1–2 business days. All stock is held domestically in Australia -no overseas delays, ever.
