doses of Dermorphin used in research

Not approved; two small 1980s studies gave healthy volunteers dermorphin by intravenous infusion to study prolactin release and spinal nociceptive reflexes. These are the amounts specific labels and studies used, linked to each source. They are references, not recommendations; a prescription label takes priority.

Human pilot (J Clin Endocrinol Metab 1983): 5.5 mcg/kg per minute IV for 30 min human pilot study · 1983 · PMID:6833466	11 healthy volunteers (6 women, 5 men)	5.5 mcg/kg per minute as a single 30-minute intravenous infusion Single session (repeated during naloxone infusion) Infusion rate, not a bolus: 5.5 mcg/kg each minute for 30 minutes (165 mcg/kg in total). The prolactin rise was blocked by naloxone.	intravenous

what the numbers mean · where they come from

terms and sources

Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Offers come from the Dermorphin price comparison; certificates from the COA library.

Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.

short answers

Dermorphin calculator questions

How much bacteriostatic water do I add to Dermorphin 5mg?

Any volume the vial holds; 2 mL gives 2.5 mg/mL, so 10 units on a U-100 syringe holds 250 mcg. More water makes each draw read more units. The table below shows 1–5 mL for every Dermorphin vial size on sale.

What changes the calculated concentration?

Only two inputs: the amount of Dermorphin in the vial and the water added. 5mg in 2 mL is 2.5 mg/mL; twice the water halves it, and the amount per draw then reads twice the units. A lot certificate’s measured content, where printed, replaces the label amount. HPLC purity is a share of peak area, not a measured mass, so it is shown only as an estimate.

What doses of Dermorphin were used in research?

Not approved; two small 1980s studies gave healthy volunteers dermorphin by intravenous infusion to study prolactin release and spinal nociceptive reflexes. The table on this page lists 2 sources with amounts, schedules and links.

What does Dermorphin cost per mg?

The lowest current US price is $129.99 for 5mg at Cenexa Labs (about $26.00 per mg, checked 2026-11-06). The calculator turns any vial price into cost per draw.
