Selected peptide preparation compatibility notes
#	Peptide	Target / reconstituted pH	Vial status	Mixing rationale & notes
—	NAD+	2.0 – 3.5Highly acidic	MUST BE SINGLE	Extreme acidity rapidly denatures and degrades delicate peptide chains if mixed.
01	MOTS-c	6.5 – 7.5Near neutral	CAN BE MIXED	Requires near-neutral pH to prevent unfolding. Safe to mix with 5-Amino-1MQ or SS-31.
02	5-Amino-1MQ	5.5 – 7.0Mildly acidic / neutral	CAN BE MIXED	Small-molecule salt structure that tolerates neutral peptide buffers well.
03	BPC-157	6.0 – 7.0Near neutral	CAN BE MIXED	Highly stable; commonly combined with TB-500 ("Wolverine Stack") or GH secretagogues.
04	TB-500	6.0 – 7.0Near neutral	CAN BE MIXED	Stable sequence; pairs well with near-neutral repair peptides in the same draw.
05	Ipamorelin	6.0 – 7.0Near neutral	CAN BE MIXED	Standard GH secretagogue; routinely paired with CJC-1295 (no DAC) immediately before injection.
06	CJC-1295 (no DAC)	6.0 – 7.0Near neutral	CAN BE MIXED	Synergistic GHRH analog; chemically compatible with Ipamorelin in neutral pH.
07	SS-31 (Elamipretide)	5.5 – 7.0Near neutral	CAN BE MIXED	Mitochondrial peptide; shares a compatible neutral pH window with MOTS-c and 5-Amino-1MQ.
08	Thymosin Alpha-1	6.5 – 7.5Near neutral	CAN BE MIXED	Stable immune-modulating peptide at near-neutral pH.
09	GHK-Cu	5.5 – 6.5Slightly acidic	CAN BE MIXED	Copper tripeptide; mixes with neutral healing peptides, though it can cause a slight sting standalone.
10	Epithalon	6.0 – 7.0Near neutral	CAN BE MIXED	Small, durable tetrapeptide; stable alongside standard neutral protocols.
11	DSIP	6.0 – 7.0Near neutral	CAN BE MIXED	Stable short peptide; usually kept single because of bedtime dosing timing.
12	Melanotan II	5.5 – 6.5Slightly acidic	CAN BE MIXED	Thermally and chemically stable; safe to pair with neutral compounds.
13	PT-141	5.0 – 6.5Mildly acidic	CAN BE MIXED	Stable cyclic peptide; typically administered alone because of as-needed (PRN) usage.
14	Sermorelin	5.0 – 6.5Mildly acidic	CAN BE MIXED	Fragile GHRH fragment; can pair with Ipamorelin if drawn and administered immediately.
15	Kisspeptin-10	6.0 – 7.0Near neutral	CAN BE MIXED	Rapid-acting signaling peptide; stable in neutral bacteriostatic water.
16	IGF-1 LR3	3.0 – 4.0Acidic buffer	MUST BE SINGLE	Requires an acidic environment, such as dilute acetic acid; neutralizing pH can cause rapid aggregation.
17	Semaglutide	7.0 – 7.8Near neutral	MUST BE SINGLE	Long-acting GLP-1 with proprietary preservatives; mixing alters solubility and release kinetics.
18	Tirzepatide	6.5 – 7.5Near neutral	MUST BE SINGLE	Dual agonist formulated for extended seven-day stability; altering the solution environment risks precipitation.
19	Retatrutide	6.5 – 7.5Near neutral	MUST BE SINGLE	Triple agonist engineered for precise depot release; best kept in a dedicated single-compound vial.
20	CJC-1295 (w/ DAC)	6.0 – 7.0Near neutral	MUST BE SINGLE	The Drug Affinity Complex covalently binds albumin; co-mixing may disrupt the binding mechanism.
21	Tesamorelin	5.0 – 6.5Mildly acidic	MUST BE SINGLE	Delicately folded 44-amino-acid structure; prone to enzymatic and mechanical degradation if mixed.
