Usage Guidelines

The use of S4 (ANDARINE) should be approached with care, proper research, and — where applicable — guidance from a qualified healthcare professional. OnBuy EU provides accurate product information to support informed decision-making. We encourage all customers to review available literature from recognised research institutions before beginning any new compound protocol.

For injectable formats, sterile reconstitution practices are essential. Always use bacteriostatic water (BAC water) for reconstitution of lyophilised peptides, store in refrigerated conditions post-reconstitution, and use sterile syringes for every administration. For oral tablets or capsules, follow manufacturer dosing guidelines and maintain appropriate cycle protocols supported by appropriate post-cycle support compounds where necessary.
