The first surprise was how many different “flavors” of sunscreen there are, from “kids” and “baby” to “sport” and “daily.” Some are water resistant to 40 or 80 minutes (they typically contain beeswax for staying power and have been rigorously tested; FDA regulations prohibit the use of the term “waterproof” anymore, so this is as good as you’ll get), others are intended as a moisturizer with SPF in a way, and they’re all broad spectrum (UVA, UVB, even UVC) and use only zinc oxide (non-nano particles) as the active ingredient.
Like other AAS, boldenone is an agonist of the androgen receptor (AR).  The activity of boldenone is mainly anabolic , with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.  Boldenone was synthesized in an attempt to create a long-acting injectable metandienone , for androgen deficiency disorders. Boldenone acts similar to metandienone with fewer adverse androgenic effects. [ medical citation needed ] Although commonly compared to nandrolone , boldenone lacks progesterone receptor interaction and associated progestogenic side effects.
