How to choose your first research peptide.
The catalog is 15 compounds plus 6 bundles. New researchers consistently get stuck at the same question: where do I start?The honest answer is: it depends entirely on what you're researching. Below is a decision tree by research goal — five axes, two recommendations each, and links to deeper comparison articles when the choice is non-obvious.
Start with the question.
Don't start with the compound — start with what your research model is supposed to measure. The compound is the tool, not the goal. Once the question is clear, the shortlist usually shrinks to two compounds and the choice between them becomes a real decision instead of a guess.

Your research is about weight / metabolic research.
Default pick
Tirzepatide 30 mg →Most published Phase-3 data, established dual GIP/GLP-1 mechanism, cheapest €-per-mg in the GLP-1 family. Safe starting point.
Alternative
Retatrutide 10 mg →If you want the newest triple-agonist mechanism in scope. Steeper effect curve, higher per-mg cost.
Your research is about recovery / injury / connective-tissue.
Default pick
BPC-157 10 mg →Best-documented healing peptide, localised mechanism, cheapest €-per-mg in the healing family. Start here if injury is localised.
Alternative
Recovery Stack bundle →BPC-157 + TB-500 + Selank. Standard healing-protocol stack, ~10 % cheaper than buying compounds separately.
Your research is about longevity / mitochondrial / skin.
Default pick
GHK-Cu 50 mg →Strongest published topical + connective-tissue data. Versatile (subcut or topical). Easiest first longevity compound.
Alternative
Longevity Essentials bundle →GHK-Cu + NAD+ + MOTS-c. Covers the three axes of ageing research at once with bundle discount.
Your research is about cognitive / nootropic / stress.
Default pick
Semax 10 mg →Cleaner cognitive effect, easier to measure pre/post-task. Best entry to the Russian heptapeptide family.
Alternative
Cognitive Stack bundle →Semax + Selank. Covers alertness AND anxiolytic axes with ~8 % bundle discount.
Your research is about growth-hormone axis / body composition.
Default pick
CJC-1295 / Ipamorelin 10 mg blend →Pulsatile, physiological. Keeps the subject's endogenous GH axis intact. Cheaper and safer for long protocols than direct HGH.
Alternative
HGH-191aa 10 IU →Recombinant, direct. Only pick this if your research is specifically GH-receptor-mediated and short-cycle.
How to size your first kit.
The other question new researchers stall on: which dosage tier (5 mg / 15 mg / 30 mg). The math is simple: every 30 mg variant in our catalog is priced ~5 % below pro-rata, so the top tier is the cheapest €-per-mg. But locking €170 in inventory you won't use isn't a saving. Quick rule of thumb:
- · Single pilot study (≤ 1 month): 5 mg tier. Get familiar with the compound + protocol before committing budget.
- · Standard 8–12 week protocol:15 mg tier. Most researchers' sweet spot.
- · Multi-cohort / multi-month research: 30 mg tier + ideally 10+ kit bulk pricing. Lowest €-per-mg, fewer reorders.
