Dosing
A common research range for Ac-SDKP is 50 mcg to 200 mcg once daily. Naturally produced by ACE cleavage of TB-4. These figures are reference points from published literature, not a prescription — your protocol should be set with a licensed provider.
Reconstitution
A typical reconstitution for Ac-SDKP is 1 mg of peptide in 1 mL of bacteriostatic water, giving roughly 1 mg per mL. Vial's built-in calculator works out the exact syringe draw for any vial size and dose.
Half-life
Ac-SDKP has an approximate half-life of 4 minutes. Vial plots the real concentration curve from your logged doses so you can see peak windows and when levels taper.
Storage
2-8°C post-reconstitution.
Reported side effects
- Hypotension (theoretical)
- Injection site irritation
Contraindications
- ACE inhibitor use (increases endogenous levels)
