Reconstitution chart: 5 mg vial
| BAC water added | Concentration | Draw for 100 mcg dose | Draw for 300 mcg dose |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 2 units | 6 units |
| 1.5 mL | 3,333 mcg/mL | 3 units | 9 units |
| 2 mL | 2,500 mcg/mL | 4 units | 12 units |
| 2.5 mL | 2,000 mcg/mL | 5 units | 15 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About GHRP-2
GHRP-2 is a growth hormone releasing peptide, a synthetic secretagogue that triggers a growth hormone pulse by acting at the ghrelin receptor. It is one of the original compounds in the class and is frequently paired with a GHRH analog like CJC-1295 for a fuller response. It has no regulatory approval. One well-known characteristic is that it can raise appetite and modestly bump cortisol and prolactin, more so than the cleaner ipamorelin.
Community protocols typically discuss 100 to 200 mcg per injection, one to three times daily, taken on an empty stomach because food blunts the growth hormone response, with a pre-bed dose treated as the anchor. Note the unit: micrograms. A 5 mg vial holds 5,000 mcg, so at 200 mcg per dose one vial covers twenty-five injections. The numbers here describe what communities discuss about an unapproved compound, nothing more.
The doses are small relative to the vial, so water is about readability. With 1 mL of BAC water in a 5 mg vial, a 100 mcg dose is a 2 unit draw, hard to measure; at 2.5 mL it becomes 5 units. The calculator flags draws under 3 units and warns when the unit toggle looks wrong, since mg in place of mcg is a 1,000x error. For a blend vial pairing GHRP-2 with a GHRH analog, enter the total content and your combined dose. Refrigerate after mixing.
Quick facts

Stop gambling on where you buy your peptides.
The calculator tells you how much to draw. The Verified Buyer's Manual tells you how to source the peptide itself without getting scammed or shipped underdosed product. Trace any compound back to the lab that made it, read a Certificate of Analysis and catch a fake, grade any seller before you pay, and price it right. A repeatable system, not a list of names that goes stale.
- How to read a lab report (COA) and spot a faked or misattributed one
- Source tracing: find verified sellers yourself from public test data
- The vetting grid: a yes-or-no scorecard for any seller
- Real cost-per-mg math so you never overpay
- Reconstitution, storage, and the first 72 hours after a package lands
