⚠️ Always use bacteriostatic water (not sterile water) for peptide reconstitution — it contains 0.9% benzyl alcohol which prevents bacterial contamination and allows multi-use dosing. Store reconstituted peptides refrigerated at 2–8°C. Most reconstituted peptides remain stable for 4–6 weeks when refrigerated.

★★★★★

"Finally a peptide resource that isn't a Reddit thread or a shady research chemical site. The reconstitution calculator alone saved me from a serious dosing error."

— Marcus T., biohacker, using BPC-157 + TB-500 stack
★★★★★

"The comparison table is exactly what I needed before my telehealth consultation. Walked in actually knowing the difference between Ipamorelin and CJC-1295."

— Sandra K., 47, longevity protocol
★★★★★

"I've been training for 20 years and this is the cleanest peptide reference I've found. No sales pitch, just the information."

Common Questions

Frequently Asked Questions

Answers reviewed against current peer-reviewed research and clinical practice protocols.

The formula is: mL of bacteriostatic water = (Vial size in mg × 1000) ÷ Desired concentration in mcg/mL

Example: 5mg vial at 1000 mcg/mL concentration = (5 × 1000) ÷ 1000 = 5 mL of bacteriostatic water. Always add water slowly down the side of the vial — never inject directly onto the powder or shake the vial.
Yes — the BPC-157 and TB-500 combination is one of the most widely used peptide stacks, often called the "Wolverine Stack." They work through complementary mechanisms: BPC-157 promotes angiogenesis (new blood vessel formation) while TB-500 drives cell migration and reduces inflammation. They are typically administered at separate injection times. Always consult a provider before stacking peptides.
Ipamorelin is a GHRP (growth hormone releasing peptide) that triggers a clean, selective GH pulse with minimal effect on cortisol or prolactin. CJC-1295 is a GHRH analogue that extends the duration of the GH pulse. Together they produce a synergistic effect — Ipamorelin initiates the pulse, CJC-1295 prolongs it. Most protocols administer them together before bed in a fasted state to align with the natural nocturnal GH pulse.
The legal status of peptides in the US is nuanced. Most therapeutic peptides are not FDA-approved for human use and exist in a regulatory gray area — they are not controlled substances (meaning possession is not a criminal offense), but they are not approved for human administration. Several peptides including Sermorelin and Semaglutide are FDA-approved for specific indications and can be prescribed by licensed providers. BPC-157 returned to Category 1 compounding status in February 2026. Always verify current regulatory status with a licensed healthcare provider in your jurisdiction.
Lyophilized (freeze-dried) peptide powder can typically be stored at room temperature away from light for several months, or frozen for longer periods. Once reconstituted with bacteriostatic water, peptides should be stored refrigerated at 2–8°C and used within 4–6 weeks. Never freeze reconstituted peptides. Keep away from light. Use a fresh insulin syringe for each draw to maintain sterility. Discard any vial showing cloudiness, particulate matter, or unusual color.
mcg = micrograms. mg = milligrams. There are 1,000 micrograms in 1 milligram. Peptide doses are almost always expressed in micrograms (mcg) because the active amounts are very small. A 5mg vial contains 5,000 mcg of peptide. A typical BPC-157 dose of 250 mcg is 0.25 mg — a small fraction of the total vial.
Look for telehealth providers that: require baseline labs before prescribing, provide written dosing protocols, use verified US compounding pharmacies (503A or 503B licensed), and offer ongoing monitoring and follow-up. Avoid sources that sell peptides without a prescription, do not require lab work, or cannot provide certificates of analysis (CoA) for their compounds. Reputable telehealth platforms operating in this space include Marek Health, Transcend, and similar physician-led longevity clinics.
