Lantus (100iu/ml) Slow-Acting Insulin

$225.00

Lantus is Sanofi’s brand of insulin glargine, a long-acting insulin analogue. It provides steady, peakless basal insulin coverage for up to 24 hours. Clinically, it is prescribed for type 1 and type 2 diabetes as the background insulin in basal-bolus regimens.

Main Clinical Uses
Provides background insulin coverage in type 1 diabetes (basal-bolus therapy)
Used in type 2 diabetes when oral medications are insufficient
Combined with rapid-acting insulins for full 24-hour coverage

Main Bodybuilding Use
In bodybuilding, Lantus can be used as a basal insulin during bulking to provide a steady, anabolic environment that enhances nutrient shuttling and glycogen storage. Its flat action reduces hypoglycemia risk compared to NPH, but requires disciplined carb intake across meals to match insulin activity.

Availability: In stock

How It Works
Lantus is engineered to dissolve slowly after subcutaneous injection, releasing insulin consistently over the day. Unlike rapid-acting insulins, it does not have a peak, mimicking the body’s natural basal insulin secretion.
