What's on the Immune & Hormonal Shelf
Ten products: Thymosin Alpha-1 (5mg and 10mg), LL-37, PT-141 (10mg), Kisspeptin-10 (5mg and 10mg), Gonadorelin, Oxytocin (8mg and 10mg), KPV (5mg and 10mg), ARA-290, and VIP (5mg and 10mg). All lyophilized vials include a lot CoA and ship same-day before 2pm EST.
Thymosin Alpha-1: 5mg vs 10mg
Thymosin Alpha-1 comes in 5mg and 10mg vials. The 10mg is the better value per milligram and is the more common choice for anything beyond a single short protocol. Both ship with a lot CoA and require bacteriostatic water for reconstitution.
PT-141 (Bremelanotide): What to Know Before Ordering
PT-141 is a 10mg lyophilized vial. It is FDA-approved (as Vyleesi) for HSDD — the only peptide on this shelf with a US drug approval. As a research compound it ships as an off-label vial at research-grade purity. Reconstitute with BAC water. Priced at the mid-range of this category.
KPV and VIP: Both Have Two Size Options
KPV comes in 5mg and 10mg; VIP comes in 5mg and 10mg. For both, the 10mg vial is the better $/mg. Both are short peptides (KPV is a tripeptide, VIP is a 28-mer) and are very stable in lyophilized form.
Oxytocin Sizing
Oxytocin comes in 8mg and 10mg vials. The 10mg is a modest step up in quantity for a small price increase — the better value per milligram. Oxytocin is one of the more price-accessible compounds on this shelf.
Gonadorelin
Gonadorelin is a single-size product in this category. It is a synthetic GnRH decapeptide and one of the most affordable compounds on this shelf — a good add-on when building an order to the free shipping threshold.
