Saturday Flashback Serum and Sinew

Saturday Flashback: Serum and Sinew

This week’s trip to the past is a roundup of stories involving growth serums of various kinds. It’s a popular mechanism, of course, so this isn’t an exhaustive list, but I tried to find a mix of stories that are at least partly about the serum itself as well as the effects, rather than tales where a serum figures but insignificantly.

The next phase of tag upgrades will include mechanism tags (serums, powders, magic, etc.), but for now the search engine is there and lets you combine tags like “muscle growth” with keywords like “warlock” or “laboratory”.

Speaking of which, last week I caught up on the tag suggestions and the description suggestions. I very much welcome any thoughts you guys have on tags that might need to be applied, so keep using the tag suggestion form. I do them manually and decide if I agree on each one, so if something’s borderline maybe go ahead and add a comment explaining your reasoning. That helps when I’m reviewing the suggestions and I get to one I’m confused by.

A reminder: it’s very much appreciated when you upvote and comment on stories you like. But on this site it’s bad form to downvote because you don’t like the kind of story. That’s one of the reasons the tags are there. If you read a story tagged “big noses”, and then you give it one star because you’re not into big noses, I gotta say you’re being kind of a dick in that moment. Fortunately that sort of abuse is very rare, and I want to give a big thank you on behalf of the contributing authors to everyone who’s been taking the time to leave helpful and constructive comments lately. Keep it up!

The next update is 13 April. In the meantime, thanks for visiting and enjoy the site!
