Insights
Proteins come in a variety of forms. Sources like whey are ideal around workouts when you want aminos - fast. Casein proteins are better between meals and before bed when slower delivery, over several hours, is preferred. Moderate-release proteins like egg and goat's milk are easily digested and contain all of the essential amino acids, which makes them great choices most other times.
PROMASIL's elite blend combines fast, intermediate, and slower-digesting sources to deliver the best of all worlds: a single protein powder that is versatile enough for all day use. Whether you drink your shake in the morning, after workouts, or between meals, PROMASIL's multi-source blend provides broad-spectrum amino acid coverage in one convenient package.

My favourite is Vanilla. Then chocolate. Cookies and cream is ok.

I've introduced my dad to it and it is helping him out now too. I am looking forward to trying new flavours from the website. The store I previously got this from only has chocolate and vanilla.

One of the best Proteins out there. I have used it sinceI started working out in 2010 and whenever I have switched or have had to switch, things just aren't the same. Not to mention the quick and amazing service that Rivalus gives to their customers too. Amazing company with amazing products.
